Physics?!?

I've decided to introduce my fifth, sixth, seventh and eighth graders to the wonderful of physics. Before you start groaning for my students, they do really enjoy it. I remember that the physic's class that had the greatest impact on me (no pun intended) was the one that related the subject to real world situations and problems. We've started on the formula for velocity and integrated it into the study of roller coasters. They're having a good time with it. Of course it also allows me to sneak in word problems which is a great way to prep our students for the upcoming AIMS testing. Hopefully next week I'll have some photos to show you.
