Fourth, fifth, and sixth graders have to do a summer project. My son chose to build a maze, and then put a rolie polie in the maze to see what would happen.
What happened is that the rolie polie insisted on climbing over the walls.
Therefore my son put wrap on the top.
For me, the most surprising thing about this experiment was how hard it was to find rolie polies. When you don’t want to find them, they are everywhere. But when you want one, you have to look under a lot of rocks.
