Students have collected 60 pill bugs and are interested in how they behave. The students mark a
line down the enter of six shallow dishes. Then, they place 10 pill bugs in each dish, give in each
half. They scatter the same amount of food evenly throughout each container and spray the same
amount of water into each of the dishes. Finally, they cover one half of each container with
, cardboard to make it dark. They cont and record the number of pill bugs in each half of each
container after 10 min.

A. Pill bugs move faster in the light than in the dark
B. Pill bugs prefer an environment with less light to one with more light.
C. Pill bugs eat more in the dark than in the light - answerB. Pill bugs prefer an environment
with less light to one with more light
