Lesson 58 Level Now we are going Court Case Against Bail be looking at liquid.

Concentrating Hydrogen Peroxide from 3% to Above 90%

Imagine those blue balls are water. When water is a solid, it is ice. What turns water you can drink into steam? Just about everything you see in this world is a solid , a liquid or a gas. A solid is a desk; a liquid is milk; a gas is helium in balloons that float. Make sure you put it in your notebook. Answers Tell a parent or an older sibling what you think makes something a solid, a liquid or a gas. Click on states. Answers Just about everything in this world is either a solid, a liquid or a gas. For example, by heating the solid ice you change it into a liquid. Level Alexander Graham Bell realized that the sound carried better if he used a liquid with his thin metal wire. Conduct a sound experiment. Does sound travel better through a solid or a gas the air?

Do Table Thunder, the second experiment. Try it a few times with different tables. If you can get what you need together, you could do any of the other experiments too. In your science notebook, describe your experiment and what your conclusion is. Your conclusion is your answer; does sound travel better through a solid or a gas? Think of a way to test whether sound travels better through a liquid or a gas. Try it. Present your conclusions at the dinner table.

Do Hang In There. Print out the science experiment page and fill it out with your experiment details. I wrote the experiment question above. Experiment worksheet Think of a way to test whether sound travels better through a liquid or a gas. Level Read about how a telephone works. Have you installed Ad Block Pro yet? Describe how a basic telephone works. Lesson 8 Level Cut out your O element booklet. Oxygen is part of what we breathe. We need oxygen for our bodies to work. It is another element in our world and is number 8 on the periodic table, because one atom of oxygen has 8 protons in it. Write or draw inside your oxygen card.

Add it to your Oxygen Group lapbook page. Not everything in the world is hydrogen or oxygen or carbon or whatever else is on the periodic table. Those are the elements that other things are made from. When different atoms come together to make something new, they are called molecules. Probably the most famous molecule is H2O. Have you ever heard of it? It means two hydrogen atoms and one oxygen atom getting together. When they do, they make water! All water you see is made up of H2O molecules.

Draw a water molecule and label the three parts each either H or O. Label your picture and keep it in your science notebook. Look at other molecules. Level Watch video on oxygen. Cut out your O element booklet. Level Remember molecules? A water molecule is made up of two hydrogen atoms and one oxygen atom, making H2O. When molecules heat up, they get really excited and move around a lot! Read about solids, liquids and gases. Read about evaporation and condensation and then do the activity below the reading. Read about the water cycle and do the activity below the reading.

Directions here. Try this online quiz. If you have a grape and a microwave, then you can create plasma. Plasma is another state of matter. Make sure you have parent permission AND supervision before you do this! Slice a grape in half longways but leave a little skin so you can open it like a book. Open it and place it in the microwave, either directly on the glass turntable OR on a microwave-safe plate. Do NOT use a paper plate or paper towel! Turn the microwave on and be ready to turn it off. In seconds you should see plasma shooting off the grape!

Turn off your microwave after those seconds. When atoms are combined, it is called a molecule. When molecules heat up, they get excited and move around a lot. This is what happens when water turns into water vapor or steam. When molecules cool down, they slow down to mostly stopped. This is what happens when water turns into ice. Ice, water and steam are all H2O. They are all made of water molecules. It is the same matter. They are just each in a different state of matter.

Watch the molecules get excited. Heat them up. Write in your science notebook each of the words in bold. As best you can, write about what each means. As a reward for writing those tough definitions, place an opened bar of Ivory soap in the microwave on a microwavable plate. Turn the microwave on for one minute. Watch what happens. You are exciting the water molecules that are inside the soap causing them to move around! Ivory soap is special because it floats when other bars of soap sink. Lesson 11 Level Another way to move molecules, other than to excite them by heating them up, is to cause them to vibrate. When there is a sound, it moves the molecules in the air, causing them to vibrate.

Make a sound wave. Tie a strong string to a doorknob and walk back until the string is straight; or take the plug of your vacuum cleaner in your hand and stretch out the cord. Move your arm up and down and send waves down the string or cord. Draw sound waves in your notebook. Level Materials: Two tongue depressors big popsicle sticks , wide-ish rubber band long enough to fit around tongue depressors the long way, two small rubber bands, one index card or some card stock Read about this experiment and try it if you have what you need. Make sure to read about the science behind it. Write in your science notebook what you learned from the experiment. Please put the date at the top of the page. Lesson 12 Level Explore sound in your house. What makes sound?

What is being vibrated to make the sound? Remember that sound can travel through a gas, a liquid or a solid. When you listened to the bang on the table, it was the molecules in the table vibrating. Make a list of your answers to the two questions as you explore your house. Level Materials: balloon Play with different instruments to make different sounds. What is being vibrated to make each sound? What makes a higher sound and a lower sound, on the same instrument?

Read this experiment. Lesson 13 Level Today, create sound. Create sound that vibrates through a solid bang something. Create sound that vibrates through a liquid fill a glass with water and tap the glass. Create sound that vibrates through the air blow over the top of a bottle, swing something fast through the air, or you could cheat and just talk! Try filling glasses up with water to different heights. Which gives a higher sound? The one with the least amount of water, because the molecules can vibrate back and forth through it faster.

If you have a bottle that you can blow over the opening to make a sound, fill the bottle with different amounts of water. It will produce a higher sound if you have more water because there is less air , and the molecules can vibrate back and forth through the smaller amount of air faster, making the sound higher. Record in your science notebook the different ways you vibrated molecules to create sound. Please write the date on the page. Watch vibrations caused by sound. Skip to 1 minute. This is a mixture of cornstarch and water on a cookie sheet sitting on top of a speaker. Level Watch this video of sound experiments, and then figure out some of your own special effects sounds. What sounds can you make with things around your house?

Leave a little opening at the end. Talk normally into the air and then through your cone. Listen to someone talking normally, and then with the small opening of the cone to your ear. Your cone is spreading out and collecting sound waves. Question: Can sound waves be amplified made louder? Level Read about the speed of sound and traveling faster than the speed of sound. Watch a video showing breaking the sound barrier. Lesson 15 Level Read about the phonograph.

Draw a phonograph. What is being vibrated? If you have a record player at your house, observe it in action. Watch the Edison Phonograph video. It starts playing at Level Read about the phonograph. Just read the top of the page. If you have a record player at home, observe it in use. You can also watch the video. Draw a diagram of how a phonograph works. The light in the bulb basically is a fine wire, called a filament, that gives off light because it is heated up and gets hot. Remember how they get excited when they heat up? The electricity travels into the bulb, heats up the atoms in the filament, causes them to jump around, which gives off the light.

To make the bulb shine as it does, it is filled with a gas to help it. The gas is called argon. Watch the video below on how a light bulb is made in a factory today. Then cut out argon booklet. Draw or write inside it and add it to your Noble Gases lapbook page. Level The light in a bulb basically is a fine wire, called a filament , that gives off light because it is heated up and gets hot. Watch video on argon. Argon is the gas used in most light bulbs. Thomas Edison learned that leaving air in the bulb would cause the filament the thin carbon wire inside to burn up. He used a vacuum to take out the air. Now we remove the air and put in argon. Read about the group of noble gases. Cut out and fill in your argon piece.

We see because light reflects off an object and hits our eye. A mirror reflects that light and changes its direction. Figure out where the light is traveling. Do this activity about light. Hint: You can see yourself in a mirror if you are looking right at it. Answers Level We see because light travels from the light source to an object, reflects off that object, and hits our eye. Watch this video about how light travels. Click on the simple activity at the bottom of the page and fill in the blanks.

Take a hand-held mirror or something else reflective—watches and rings might work and find a light to reflect. Make a light dance around the ceiling by reflecting it off your mirror. Get a glass of water. Use a clear glass if you can so you can see inside well. Place a pencil or straw inside the cup. Does it look like the pencil is bent? The light bends when it hits the surface of the water. Question: Can light bend? Want more? Then try this experiment on bending light. Level Materials: metal spoon Get a metal spoon. Look at yourself in it. Turn it over. What do you observe? Remember, what you see is the light reflecting off of something. Because the top of the spoon is curved down, the light bounces off and heads down, so we see our forehead at the bottom.

The light that hits the bottom part is bounced up by the curve, so we see our chins at the top. On the other side we see ourselves stretched out. In what direction does the light bounce? Draw a picture of light hitting a spoon from both sides. Where does the light bounce to? Level Read this page about reflection and refraction. Answer: With reflection, the light is bouncing back towards you. With refraction, the light changes directions, but keeps moving forward. Place a glass of water on the end of a white sheet of paper near a sunny window. Let the light shine through the water. What do you see on the paper? Light is made up of colors. The light waves of different colors travel at different speeds and so bend in different ways going through the water.

The water demonstrates light refraction , a change in direction due to a change in speed. The water slows the light waves and causes them to bend. Play with this color mixer. Use the sliders to adjust the amount of light from each color bulb. Make sure you observe mixing all three at their highest levels. You can see how light is white, but it is really made up of many colors. Level Because of what we know about how our eyes see light and how our brains receive those signals, people have developed many optical illusions. Want to see? Here is one. The pictures on the right and the left are the same. The blocks A and B are the same color. Here is another. Level Read about the structure of a light bulb.

Play this game to experiment with different circuits. Make a circuit. It has to connect in a circle. Write circuit , conduct and filament in your science notebook and write definitions for the words. Watch the video on atoms and molecules. Stop at 3 minutes, when it starts talking about states of matter. Fill in the blanks on the worksheet. Answers Draw a hydrogen atom. It is number 1 on the periodic table so it has one proton and one electron. Draw a circle around that for your electron to travel on. Draw a — sign for your electron on that circle. When you hear a new word, jot it down on the top of this worksheet. After the video is done, fill in more about each word you wrote down.

Also write in your notes the explanation as to why atoms join together. Fill in the bottom of your worksheet. Keep it in your science notebook. Go back in your science notebook and read what molecules are if you are unsure. Molecules have different shapes. Take some salt and sugar and look at them with a magnifying glass. Do you see their shapes? Salt Sugar With adult permission and help, heat one cup of water on the stove and add three cups of sugar.

Add a little at a time, stirring to dissolve. When it is all dissolved, pour it into a clean jar. Tie a string to the middle of a pencil. Tie a paper clip to the other end. Lay the pencil across the top of the jar so that the paper clip and string hang in the liquid. Let it sit a few days and watch the sugar crystals grow. The sugar crystals are just sugar molecules attaching together. Write up your experiment. You can use this experiment worksheet to help you. Stir for one minute there should be some Epsom salt crystals at the bottom still and then place in the refrigerator. In three hours you should have crystals. You can click on it to see it bigger. Epsom salt is magnesium sulfate, MgSO4 That means that each molecule of magnesium sulfate is made up of one atom of magnesium, one atom of sulfur and 4 atoms of oxygen.

The crystals are lots and lots of molecules joining together. Draw a picture of what a magnesium atom might look like. It is number 12 on the periodic table so it has 12 protons and electrons. Now draw a ring around it with two electrons - on it. Now draw a second ring around that. The second level can hold 8 electrons, remember? Draw eight electrons on the second ring. Now draw a third ring around the atom. How many electrons should you draw on this one? This last level, or its valence shell, needs 2 more drawn in, but it wants 18! Look at this picture of enormous crystals. Have Epsom salt left over? Try this! You can save some for later as well, a tablespoon should do.

Lesson 23 Level The next element on the periodic table you will work on is helium. Helium is a gas. You may have heard of helium balloons. Those balloons that float away if you let go of them are filled with helium. They float because they are lighter than air. Remember the lighter the element, the earlier it is on the chart. Helium is number 2. So if helium floats, do you think hydrogen balloons float too?

Of course! Hydrogen is lighter than helium. So helium is number 2 on our periodic table. That means it has 2 protons in its nucleus , center. That means it also has 2 electrons flying around it. Cut out helium piece. Write or draw inside about helium. You could also draw a helium atom inside. Add it to your Noble Gases lapbook page. Level Read about helium. Page 1 Page 2 Watch the video on helium. Helium is number 2 on the periodic table because it has 2 protons. Check out this site on helium. Use the different links on the right. Cut out the helium piece. Write inside about helium.

Draw a helium atom inside as well. Helium belongs to the group of noble gases. Every element in a group has the same number of electrons in its valence shell, except for helium, which only has 2. How many electrons do they each have in their valence shell? Use neon to figure it out. First shell 2, second shell 8, right? Now check it with argon, number Does it work?

Remember argon? Lesson 24 Level Draw a picture of your sugar crystals. You can use the back of your experiment worksheet. You can eat them if you have permission. We know that the atomic number is 2. We also know that the atomic number is also the number of protons. Fill in that information on your chart. Periodic table charts tell us that its atomic mass is 4. Fill that number in. Its mass number is 4. Now protons are the positive charge in the nucleus. There has to be an even negative charge to balance it out. That means there the same number of electrons the negative as protons the positive. Fill in the number of electrons on your chart. There are 2 neutrons in a helium atom. Fill in the number of neutrons on your chart.

Level Materials: as many pennies as you can find—20 would be great — or any coin you have the most of, or something like checkers would work too Take your coin collection all the same coin and lay them flat on a table and push them together so that they are all the way touching. Look for patterns. Do you see how they line up? Do you see how they surround each other in the same shape, even though you put them together randomly? Draw a picture of your coins all together. This is similar to your crystals. The molecules formed a pattern when they grew together as crystals because of the structure of each molecule.

Answers Do you remember seeing this in the video from Lesson 21? Fill a cup with water to the very top. Start dropping in coins or something else. How many did you get in? What is holding the water in place is called surface tension. Watch this video on surface tension. Answers Watch this video on surface tension. Get a bowl of milk. Sprinkle in a handful of O-shaped cereal or ball-shaped cereal.

Do they race towards each other and touch each other? This is a big picture of how molecules attract each other. Pour a spoonful of water into a bowl. Add food coloring if you like. Add drops of oil to the water. What happens? The water seems to run away. What is happening is that the water molecules are attracted to the water molecules and the oil molecules are attracted to the oil molecules, so they stay separate. Add some dish detergent. The water and oil molecules are both attracted to the dish detergent molecules. Draw a picture of molecules attracting. What shape does it sit in? Water cohesion , or how water molecules are attracted to each other, is why the water beads up.

Fill the tablespoon so that the water seems to mound up over the top of the spoon. The molecules on top are attracted to those underneath and hold onto each other. This creates surface tension. Fill a cup with water. Place a paper clip or pin on top of the water. The cohesion builds up a strong surface tension. It holds the water in place and the paper clip on top. Read about water cohesion. Make sure you start with an introduction sentence that says what you are going to write about.

Lesson 28 Level Read about carbon. Cut out your carbon piece and write or draw about carbon. Add it to your Carbon Group lapbook page. Level Watch this video on carbon. Read about carbon. Cut out your carbon piece and write about carbon inside. Level Materials Level container—empty 20 oz. Hydrogen peroxide is H2O2. It changes to H2O and O, water and oxygen. The yeast makes the change happen more quickly. The dishwashing detergent mixes with it, creating the foam. If you notice it says O2 and want to know why, highlight the answer: O, oxygen, never is alone as a single atom. It will always pair up with something. So oxygen really only exists as O2 because it will always pair up. It will find always another O! You just witnessed a chemical reaction, or a change in a chemical.

Explain the chemical reaction in this experiment. Fill a glass halfway with seltzer water. The reaction just takes a bit longer. Add a drop of food coloring. Pour in bleach and watch the color disappear. The color disappears because the oxygen molecules in the bleach and the oxygen molecules in the water bond together. Watch this video of a neat chemical reaction. This is sulfuric acid being poured into sugar. The acid reacts with the sugar and takes all the H2O out of the sugar. That leaves only carbon! Someone suggested this more modern video. It has a better image, but it also has ads. Here is a notebooking page you could use.

Write a definition of chemical reaction. Sugar is C12H22O Do you see that H22 and O11 could make 11 water molecules H2O? Someone suggested this more modern video of the reaction. Aerodynamics Lesson 31 Level Read this page on flight and look at the images. What are two types of flight? How are airplanes similar and different from flying animals? Level Read this page on flight and look at the images. Explain the different kinds of flight. Watch this video of the world record paper airplane throw. It starts falling but then goes up again. How is it flying? Take notes! Put a little hole in the middle of it. Pull the string through the hole so that half is up and half is down. Tape it in place. Lay the straw along the middle of it.

Cut out these labels, flight forces , and tape them onto the string and straw. We are going to learn about each of these forces in flight. Hang your plane somewhere if you can. Level Read this page on forces in flight. Draw a diagram of the four forces which control an airplane. This is an overview. Okay, if you want, you can make a paper airplane like the elementary school kids are doing. Level Materials Level coin, bag of coins The first force in flight we are going to look at is gravity. It is; you called it weight. Gravity is what gives us weight. It is actually gravity pulling down on our mass that makes the scale go down, showing how much we weigh. Your mass is how much matter you are made of. Gravity pulls on all mass with the same force.

Gravity is always pulling everything at the same speed. Hold a small coin in the air. Let go. It fell, right? Well, actually, gravity pulled it down to the earth. Now do the same with the bag of coins. Same thing? Now, your bag of coins should feel heavier than the one coin. Which will fall faster? Drop both at the same time. Did they hit the ground at the same time?

Because gravity is always pulling everything at the same speed. Now test a bunch of other things. Do you have a golf ball or tennis ball in the house? Try dropping other things together. Now, air can get in the way sometimes. Air pressure will push up on objects that are more spread out than others. Here is this experiment done on the moon where there is no air to get in the way. Watch the video. Now go tell someone all about it. Someone sent me this second example of the experiment. Level Materials: Two coins, ruler Watch this video. Describe what happened. Did you expect something dropped and something shot out to land at the same time?

Do you want to try it? Place a coin on the edge of a table. Put a finger in the middle of it to hold it to the table. Place the other coin same type of coin on the edge of the part of the ruler that is hanging off the table. Works best where you can hear the coins hitting the floor. You are going to quickly hit the very end of the ruler that is hanging off the table. When you do that, you will be knocking it out from under the one coin so that it drops and you will be striking the other coin so that it flies off.

Try it several times. The more mass, the more gravity pulls on it, which is why we all weigh different amounts even if we all fall at the same speed. Also, every object has a gravitational force. You have a gravitational force attracting everything to yourself! The Moon pulls things towards itself too. Watch this astronaut jump around , showing that there is less gravity on the Moon. For the next one skip to and watch him jump two times. You are going to fill in a worksheet that shows how much you would weigh on each planet. Each planet is a different size, so it pulls down on your mass with a different amount of gravitational pull. Write your weight on earth in the box and use a calculator to multiply. Explain to someone why you would weigh less on Venus.

His mass is the same, but his weight gravity pulling on his mass is different. He is pulled to the Moon with less force than on Earth since the force, the speed at which gravity pulls, is less. Makes it seem to us like it is slow motion. Materials: straw, cup of water We learned about gravity which pulls airplanes down. How does air keep up an airplane? Watch the video for the first three minutes. Take a strip of paper. Hold it up to your lips.

Blow over it. Blow under it. When does it go up or down? When you throw a frisbee, what is holding it up in the air? Does air pressure really hold things up? Stick a straw into water and hold your finger over the open end. Take the straw out of the water. Is the air holding the water into the straw? Level Materials: cup of water, index card or cardboard or stiff paper. Level Materials optional: balloon, 2 liter bottle — empty Watch the video below on air pressure. Try this experiment : stretch a balloon over the opening of an empty 2 liter bottle. Place the bottle in a pan or bowl of super hot water.

The air inside the bottle will heat and expand, creating more air pressure. It will press on the rubber of the balloon and expand it a little. Place the bottle in a pan or bowl of ice water and the balloon will deflate. The air in the bottle will cool down and the air pressure will lower and stop pressing on the balloon. Blow a ziplock bag.

Seal it almost all the way. Give it another big puff and seal it closed. Put it in the freezer. Check on it in minutes. Did it deflate some? Air pressure is lower when the air is cooler. Watch the video below on air pressure. You can try it if you like. Can you answer the questions? The air lifts the plane up. A helicopter works in a similar way. The airplane drives forward, pushing the air over and under the wings, creating the change in pressure so it can lift off. A helicopter twirls its blades to move the air over them. They are also creating higher air pressure under its blades which causes the lift.

Use the template to make the paper blades. Drop it and watch it in action. Make observations? Tell how lift is created with your motor rotor. Tell how lift is created with your boomerang. Here is a YouTube video with directions for an origami boomerang. Get permission before going to YouTube. Level Materials: balloon, straw, fishing line or strong thread or something similar Take a straw and hold it in the air. Let go of it. It falls, right? What needs to happen to make it fly at least a little bit? It needs thrust , a push in the right direction. Do the extra experiments if you like. Level Materials: paper towel tube, flexible straw, paper cup, aluminum foil Today you will learn about thrust, the push that moves the plane forward.

Read through part 1. Build an engine part 2 of the booklet. Lesson 40 Level Review the flight forces: lift , thrust , weight , drag. Describe to someone each force and what it does. Level Do the activity on flight forces. Because it thrived in warm conditions, however, it was determined to be the culprit of the Hot Tub Rash, in which direct contact between the skin and the infected water from the tub will make the infected skin itchy and turn it a bumpy red color In addition, P. Although most P. This characteristic, along with the fact that P. Psuedomonas aeruginosa is unique due to its ability to infect both humans and plants, one of the few organisms that can infect both kingdoms.

Depending on their locations, biofilms can either be beneficial and detrimental to the environment. For instance, the biofilms found on rocks and pebbles underwater of lakes and ponds are an important food source for many aquatic organisms. On the contrary, those that developed on the interiors of water pipes might cause clogging and corrosions 19 It is usually linked with patients whose immune system is compromised by diseases or trauma. First, P. Since the powerful exotoxins and endotoxins released by P. Furthermore, with the exception of the cystic fibrosis strain, most P. And even though a small amount of patients infected by P. Cystic fibrosis CF is the most common autosomal recessive disorder in Caucasians.

This disruption in the salt and water balance in the cell results in the production of a thick mucus, which becomes the ideal home for potential pathogens. At this location, P. Once this is formed, the P. This gives them the ability to resist many defenses, including anti-Pseudomonas antibiotics such as ticarcillin, ceftazidime, tobramycin, and ciprofloxacin, because once the bacteria sense that their outer layer of biofilm is being destroyed, the inner layers will grow stronger to reestablish the community This form of communication allows the cells to regulate gene production which results in control of certain cell functions.

One of the enzymes responsible for quorum sensing is tyrosine phosphatase TpbA. This enzyme relays extracellular quorum sensing signals to polysaccharide production and biofilm formation outside the cells Quorum-sensing can be a drug target to cure infections caused by P. Quorum-quenching is used to blocks the signaling mechanism of quorum-sensing and prevents biofilm formation in P. Yi-Hu Dong and his colleagues were able to prevent biofilm formation in mice under laboratory conditions For example, exotoxin A, the most toxic protein produced by P. Moreover, elastase, an extracellular zinc protease, attacks eukaryotic proteins such as collagen and elastin and destroys the structural proteins of the cell. It also breaks down human immunoglobin and serum alpha proteins 1.

In an experiment, intravenous injection of virulent P. When a smaller dose was injected, characteristic signs of infection such as weight loss, focal lesions in liver, spleen, and kidneys, followed by death within days, would take place. Pseudomonas aeruginosa is an environmentally ubiquitous opportunistic pathogen. Epidermal infections often result from P. Following severe skin damage, the prevalence of P. Previous research of antibody-mediated host defenses indicates that on the fifth day after the initial burn, Fc receptor expression is reduced in polymorphonuclear leukocytes PMNs. Furthermore, any P. The pili and flagella of P. Controlled infection of burn wounds on animal and plant models with P. Without these morphological virulence factors, the bacteria exhibit a substantially decreased survival rate at the wound site and a decreased ability to disseminate within the host organism [36].

The spread of P. Elastase also assists P. The field B is a partial magnification 3 times of A. Date: Metabolism: Is often classified as aerobic, but can also exploit NO3- as final electron acceptor in the respiratory chain. Should, therefore, be classified as facultatively anaerobic! Hosts: Cattle, dog, horse, mink, poultry, sheep, reptiles etc. Methylbenzenes are considered as environmental contaminants that are present in the atmosphere, underground and soils, and in surface water Hence, P. In this experiment, three microbial pathogens Pseudomonas aeruginosa , Salmonella typhimurium , and Candida albicans are being brought into space to see how their genetic responses and virulence change.

These three microbes have been viewed as potential threat to the health of the astronauts, for P. The microbes were placed inside self-contained culture chambers and upon landing back on earth, one thirds of the sample will be used for virulence studies while the remaining will be kept frozen at oC. Because this is an ongoing research project, there have not been any results but NASA scientists are very hopeful that this study will lead to novel discoveries of vaccines against these microbes here on Earth and during spaceflight These methods, however, have some disadvantages because P.

It was then proposed that serology and polymerase chain reaction PCR might be better techniques in detecting the early stage of P. The experiment was carried out by collecting sputum and serum from 87 CF children with a mean age of 9. Then, 1 PCR was performed on the sputum, targeting P. When looking at the results, using the PCR or serology method alone did not yield statistically significant difference from the microbiological culturing methods. The combination of PCR and serology, however, identified a lot more patients than any of the two methods alone.

Hence, a combination method that includes PCR will be an accurate technique to use in early diagnosis of P. Then, a long-range PCR based method was implemented to determine if certain P. It was found that although PA14 gemone 6. There were 58 gene clusters from PA14 that were missing in PA01 and it was assumed that some of these genes are what make PA14 a lot more virulent than PA Microarray genomotyping of 18 diverse strains in the C. Thus a conclusion was drawn that the virulence in P. Under iron deficiency, a yellowish-green fluorescent pigment develops as a result of pyoverdins, a term named by Turfreijer for a group of compounds having a 1S amino-2,3-dihydro-8,9-dihydroxy-1H-pyrimido-[1,2a] chinolincarboxylic acid chromophore.

Figure 6A shows the different types of Pyoverdin groups that can be made on variations of their peptide chain. These pigment compounds only grow under iron limitation in a growth medium. Figure 6A shows the three different sv subgroups of Pyoverdin of P. Since these three pyoverdin structures also known as ferri-pyoverdins are not produced by any other species of Pseudomonas they can be a quick way to identify the specific bacteria, Pseudomonas aeruginos.
