`** How Temperature Affects the Growth of a Caterpillar ** By: Tori media type="custom" key="3598878" For my project, I put 6 painted lady caterpillars in a cold area and 6 caterpillars in a warmer area. In the bottom, there was food. The warmer caterpillars ate more and grew almost twice as much! When all of the caterpillars turned into a cocoon, I transfered them to a net. In the net, they would hang until they hatched. Since I cannot release them until the temperature stays above freezing, they are now living at my house in the net. I feed them sugar water and spray them each with warm water. Unfortunately, their life span is only 2-3 weeks. So they will not be around much longer. I recorded the temperature every day and what stages they were in. The warmer caterpillars turned into cocoons faster and hatched earlier. Also 5 of the 6 warm caterpillars grew into happy butterflies when only 3 of the 6 cold caterpillars did. The temperature in the warm area ranged from 74-81 degrees F. while the colder area ranged from 65-70 degrees F. The suggested temperature was from about 70-75 degrees F. I found that when the temperature became extreme (80 or 60 degrees F.), the caterpillars would lie on the ground and do nothing. So I tried to keep the temperature in the middle. I ordered the caterpillars from []

=How does temperature affect Dissolved Oxygen and fish? By : Kallie = media type="custom" key="3598706"
 * || Fish 1 (Jumbo) || Fish 2 (The Friend) || Fish 3 (The Twin ) ||
 * Hot || Swam in circles around the top of the bowls || Same as fish 1 || Same as fish 1 and 2 ||
 * Room Temperature || Swam down to bottom and moved around quickly from spot to spot || Swam down to bottom and moved around quickly up and down || Swam back and forth in the middle ||
 * Cold || Swam immediately to the bottom and started freaking out || Swam to the bottom and just stayed there || Swam near the middle and nosed around ||

The other part of the project tried to find out how temprature affects the amount of dissolved oxygen in water and found out that there is more dissolved oxygen in cold water than hot water.

I bought five different plants and watered them with 25 milliliters of vinegar, with a PH of 2.54, every day for a week. The five different plants were parsley, which is grown by farmers in shady areas mostly in California. Kale, which is grown by farmers in Europe,daisy, which grows wild in the US and England, Pansy, which is a weed which grows in England, and Romaine lettuce, grown mostly in California in the US. **

 * Hello.My name is Simone. For my science project I researched and presented ** " //How Air-temperature Affects Plants" **to my class**. **I used four Venus Fly Traps ( each in acrylic boxes),five therometers,water,serand wrap and crickets. The day** //**before my expirament, I misted and fed each fly trap in the morning and in the afternoon.** **On the day of the expirament I misted and fed each fly trap for the last time. After that, I put a thermometer in each acrylic box and wraped two of the boxes in serand wrap. My teacher kept the fifth thermometer as the control. I later placed two of the fly traps by the window(one wraped in serand wrap and one without) and another by a refrigerater, to get a cool air( one wraped in serand wrap and one without). My hypothesis was that the plants by the window would survive longer than the plants by the refrigerater. I found out on the next Monday that my hypothesis did not work. The plants by the window died faster than the plants by the refrigerater. I think the plants by the window died faster because of the cold weather we had that week.Venus fly traps are use to warm, tropical weather. Thank You for listening and reading.**

How do Fish React to Changes in Their Magnetic Field? media type="custom" key="3574688" Hello, my name is Steven. My project was on how fish react to changes in their magnetic fields. I found that the fish became more active the higher the magnetic field was, but to a certain point they become irritated. Fish owners who want their fish to become more active may want to put magnets in their fish bowls, though I __**DO NOT KNOW THE SIDE EFFECTS! [|usa today.com]**__

=Rats in different environments. By Andrew=

media type="custom" key="3567454" media type="custom" key="3575624"Basicly for my project I got two rats and placed one in cage that was dark and one in a cage that was light. My project lasted for about three weeks with my light rat in the end weighing about 4.80 Oz, while my dark rat weighed anout 4.50 Oz. Also I learned that the light cage rat was more active and not shy, while the dark cage rat was very shy and scared.

Plants have three basic responses or reactions to light. They are photosynthesis, phototropism and photoperiodism. Phototropism is the plant's movement in response to light. Have seen a houseplant that leans toward the window? That is phototropism. Growth hormones are produced which cause the stem cells on the side away from the light to multiply causing the stem to tilt. The leaves are then closer to the light source and lined up to intercept the most light. Photoperiodism is the plant's reaction to dark and is controlled by the phytochrome pigment in the leaves. The pigment shifts between two forms based on whether it receives more red or far red light. The reaction controls several different plant reactions including seed germination, stem elongation, dormancy, and blooming in day length sensitive plants. Some plants are so sensitive to light that if the dark is interrupted by even a blink of light the plants will not bloom .http://www.emc.maricopa.edu/faculty/farabee/BIOBK/BioBookPS.html []

Do animals transfer bacteria from place to place?

My question was how much does my lizard rely on its parietal eye. The eye is a sensory organ on the top of the lizards head it allows him to find food in the wild. I tested the lizard in a box with an area cut off for crickets to sit in. this would be the prize. I did three tests one with the lights on, with the lights flickering, and the lights off. The lizard was stunned in all three tests so he must not use his that much.

media type="custom" key="3576802" Iain's project I have done a project in my science class and tested it many times on our class mouse Pinky. Like I said in my video the mouse was not scared during any of my tests. I really think that I proved that mice are not scared of the scent of dogs nor cats. I am looking forward to do more research on cats versus mice and dogs versus mice.My link is http://blogs.townonline.com/brookline/wp-content/uploads/2008/02/fat-baby-mouse.jpg

=Do Asian Lady Beetles Prefer Dark or Light=

//media type="custom" key="3590216" Imari !! __My project question was do Asian Lady Beetles prefer light or dark? For my experiment I took 2 tin cans and a toilet paper roll, I cut a hole on the end of each tin can. I stuck the toilet paper roll in the tin can wholes. I covered one side with aluminum foil {dark side} and one side with plastic wrap{ light side}.__//

=How are mealworms effected by the shade and light?= media type="custom" key="3597202" width="105" height="110" My project was to do demenstrate how mealworms are effected bt the light or the shade. It will also explain basic facts and interesting facts about mealworms. For my project I put a different amount of mealworms in a container and covered half of the container with cover to shade it. The other half I put a lamp over it to create light. So pull up a chair and enjoy a fun and exciting time dealing with mealworms.

=Microwaved Plants=

=
What I did for this project I microwave some seeds. I microwaved the seeds for 30, 60, and 90 seconds. All three of the plants didn't grow. The experiment was really fun because it looked like the seeds were going to pop when they were in the microwave. If you want to try this experiment it was really fun. NASA also did a experiment like this but they used radiation from the suns ray. I had alot of fun with this experiment. All you need is seeds, soil, flower pots, and a microwave. I found this experiment online [|here].====== By: Nicholas

=**How does food motivate animals?**= media type="custom" key="3623009"


 * I tested three animals,a rabbit ,a hamster ,and a rat, in a maze to see how long it would take each of them to get to the center of the maze. In one of my tests there was food in the center of the maze in the other test there was no food in the center of the maze.Here are my results:**

**The rat's time with food was 3:35 and his time without food was 10:05.**

 * The object of this experiment was to see if food would motivate the animals to get from one unfamiliar place in a maze to another unfamiliar place in the same maze.I wanted to see if any difference between the species would have any effect on their times.
