Learning to Be a Scientist: Week 3, Day 3 (skipped)

Learning to Be a Scientist: the third concept is "Scientists make observations," the third activity is "Which Is Easier?"

This activity requires a wagon, which I do not have and I could not find someone to borrow one from. I don't even have something with a platform and wheels to test it out. The activity is to try pushing a heavy object in a box and then again in a wagon and compare and decide which was easier. It's a neat example of the wheel as a simple machine. We will be doing the Evan-Moor Simple Machines book next, so I'm not going to stress about them missing this lesson.
