Classroom Close-Up
"We set a challenge for the kids: Build a long ramp for a hardboiled egg. See if you can get the egg to roll all the way down the ramp into a padded shoebox. The kids were really enthusiastic. They worked in teams. Some groups created really complex ramps. One child discovered that, depending on how you placed the egg, it would either roll or slide. When we used the PVC piping, we had to slide the egg down the track so it would fit, but on the cardboard ramps, we could roll the egg down."
