Abstract/Background: This experiment was to observe the interaction of Isopods with abiotic and biotic factors. The Isopods were found in a garden and brought in the the lab. In the lab, each group of students pick a control variable and a dependent variable. Problem: In this experiment, Isopods will be observed to see if paper saturated with the color blue is preferred over paper that is saturated with the color green. Hypothesis: The Isopods will prefer the paper saturated with the color blue over the paper saturated with the color green. Materials: • Paper towels, cut into circles • 10 Isopods • Petri dish • Control dish • Two markers ( non toxic blue/green) • Timer • Pencil/paper • Graph Procedure: 1. Gather Isopods into a container. Isopods can be found in gardens or moist, planty areas. 2. …show more content…
Gather paper towels, Petri dish, Control dish, blue and green non toxic markers, a timer, and pencil and paper. 3. Colored two paper towels one green the other blue and one was left as original color. (cut paper towels to the size control dish.) 4. Take one paper towel that is colored and put it on one side in the bottom of the control dish. 5. Then put the regular paper towel on the other side in the bottom of the control dish. 6. Take the 10 isopods and put 5 on each side. 7. Once there are 5 on each side put the petri dish over the top so the isopods can’t escape. 8. Get the timer and time the isopods for 10 minutes. 9. Use the pencil and paper to record data of the isopods’ interactions. 10. Repeat step 4 through 9 for the other colored paper towel. 11. When experiment is all done graph the results on the same graph to see what color the isopods prefer. Data: According to the charts, the isopods preferred the blue paper over the green paper. There were far more isopods in the blue and more often than there were Isopods in the green. The Isopods may have thought it felt more like being under a
Abstract: The main focus of this lab is on animal behaviors in terrestial isopods, also known as pillbugs. There are many purposes to this lab experiment. First, these pillbugs are put into four different types of enviroments, also known as chambers, light v. dark, hot vs. cold, moisture vs. dry, and lastly shelter vs. open. In these different chambers, there are 10 pillbugs, 5 placed into each individual chamber and then observed for up to 5 – 10 minutes. In this lab we observed that pillbugs prefer light areas, hot temperatures, moist environments, and lastly sheltered spaces.
Once acclimated, the isopods walked around the arena for five minutes and go to the sponges that they preferred. The experiments should be repeated 3 times with the same design layout for accurate results. 20 isopods were released in the center of the arena. After five minutes, the number of isopods behind every sponge was
Data Analysis: See attached Discussion The hypothesis that the light and dark blue prey will survive because their colors will blend in with the fabric, making it hard for the predators to find them was rejected as shown by the data. The data showed that red colored prey had the highest number of survivors followed by the green prey. The red colored prey was 32% of the population, followed by green with 24%.
Overall, the lab provided expected results. Most of our hypotheses were correct, including Dim vs. Red, Dim vs. Blue, and Dim vs. Black. We hypothesized that Drosophila Melanogaster would prefer dim light over all colors, especially blue and black due to the fact that they have very short wavelengths which are lethal to the flies. However, results from 2 out of our 5 trials did not support the hypotheses. In the initial trial, Dim vs. Dim, we expected an equal number of flies on each side of the chamber due to the same lighting on both sides.
I wish I was experienced enough to now go into detailed instructions of how to do this, however, this was our first attempt at making any version of this
Materials 10 Isopods (Pillbugs) Isopod choice chamber Paper towels Stop watch Graph paper Methodology We will put 9 out of the 10 bugs on the dry side of the choice chamber by hand, leaving one in the middle of the choice chamber to make a decision.
Hypothesis: If four lights (UV Light, LED Light, Infrared Light, and Blue Light) are used to perform photosynthesis on a spinach leaf, then the spinach will respond most to the blue light and perform a more efficient photosynthetic process.
This is a close up of a pattern found in skin of Cephalopods. A close up shows how it consists of a great amount of individual cells , which change their pigmentation and shape depending on a situation. According to a background , these cells immediately change their appearance , allowing Cephalopods to be the masters of camouflage. Some Cephalopods use the ability to change appearance not only to hide but also to indicate and communicate between each other. For example, blue ringed octopuses are called that way for having blue rings located all over their bodies.
This was decided because in our prior experimentation it was discovered that the Isopods prefer the environment with water over the dry environment. This experiment was the epitome of taxis, in which the Isopods moved directly towards the environment with water. We then became eager to see if that was applicable to any wet environment or if the specific substance caused the preference to
The pipette was used to put the water into the behavior tray to create the wet environment in the second part of the lab. The water was used to create the wet environment. The procedure for the control part of the experiment starts by taking the Animal Behavior Tray and placing the filter paper in both sides of it. Next take the five Pill Bugs and place them into the behavior tray. Start the timer on the watch and observe the amount of Pill Bugs on each side of the behavior tray and how they are acting.
Many tests were taken, putting the tardigrade specie in danger, and they seem to have won the fight in the

Gather all materials: Safety goggles, 250ml beaker, water, hot-plate, test-tubes, paper bag tear, stomach contents, pipette, Biruet solution, Benedict’s solution, and Iodine solution. 2.) Put on safety glasses.
Step two: Students placed their samples from the lake into four separate pans, which would later be carried to the lab to be analyzed. Step three: Before leaving the field there was about 16 round finfish that was captured and released back into the lake. Step four: In the lab, each student was placed in four different subgroups and given a pan full of samples from the lake. In each subgroup, students
