Question

what is your hypothesis for this experiment?
a pillbugs will have random movements between chambers, because they are indifferent to cornstarch
b. pillbugs will move away from the choice chamber containing cornstarch, because they are repelled by cornstarch
c. pillbugs will move toward the choice chamber containing cornstarch, because they are attracted to cornstarch
what is your strategy?
a. i will add 10 pillbugs and then continue to add pillbugs so that the number of pillbugs in each container remains equal
b. i will add 5 pillbugs on the left and 5 pillbugs on the right and count the number of pillbugs on each side at regular intervals of time.
c. i will put one pillbug into the choice chamber and see where it immediately goes.

Explanation:

1. For the hypothesis question: Pillbugs (isopods) feed on decomposing organic matter, and cornstarch is a carbohydrate source they are naturally attracted to, so they will move toward the chamber with cornstarch.
2. For the strategy question: A controlled, replicated experiment with equal initial pillbugs on both sides and regular counts ensures reliable, quantifiable data on their movement, which is a standard method for this type of behavioral study.

Answer:

1. Hypothesis: C. Pillbugs will move toward the choice chamber containing cornstarch, because they are attracted to cornstarch
2. Strategy: B. I will add 5 pillbugs on the left and 5 pillbugs on the right and count the number of pillbugs on each side at regular intervals of time
