Think about what you have learned about the environmental needs of the isopods and the hermit crabs. Why do you think that we created two separate environments for them? Use the class data, observations of the animals and information you may have learned from books to support your answer.
Today we set up an experiment to try to determine the optimum amount of moisture for hermit crabs. Look at the attached videos and then respond to these questions: Do all of the experiments look similar? Do you think that this was a “fair” experiment? Why or why not?
