Transfer 5 isopods to each side of the chamber (total of 10). A control experiment was then performed to ensure that the woodlice were not influenced by other factors when choosing their area to settle within the choice chamber. A closer look at suitable test animals can reveal fascinating patterns in their behaviour. The iron atoms lose electrons (the chemical 4. A-level practical assessment.

Wait 4 minutes then record the number of maggots in the left and right halves of the choice chamber. OR There will be no preference for either the decomposing or fresh apple. Prepare the choice chambers according to what you will be testing out. This is a good method to use because the dietary behavior is can easily be determined by testing the hypothesis and observation (Rustad, 2009).Once the pillbugs were able to choose their presence, the experiment was timed to observe weather they moved after an extended period or if they remained. To prepare the chamber, we put two filter papers on either side and added water to one of them and HCl to the other. Good for AP Biology. • The muslin cloth is trapped between the top and the bottom of the chamber and the woodlice can walk on the cloth.

Generally, filter paper or paper towels can be used to test chemicals such as alcohol and vinegar. A choice chamber is an effective way of finding preference; however it was not a realistic living environment. Then we put the dry towel on the other side. Students should, after this time has passed, be able to see which conditions their chosen animal prefers. Thus, in this experiment we were not looking at the internal mechanisms of the mealworm, but rather simply how it reacted to certain stimuli. About me. 6.
