Force and Motion -- Marshmallow Shooters!

Whew! I needed a blogging break. Keeping up with this blog and my classroom blog for parents was stretching me thin. But I'm back with some fun science activities to teach force and motion!

This week we are learning about push and pull, friction, and how to measure movement. When I saw this idea from Real Simple magazine (my FAVE!), I knew it would be the perfect fun for this unit!


So after I had these made, I gave all of the students a few marshmallows to eat....just to get that out of the way! The rest were STRICTLY used for Science!

We discussed and demonstrated that little force won't move an object very far (or very fast), but if you use BIG force, it will move faster and travel farther. Wow, they had fun practicing that with their marshmallows!

We also discussed how we can measure how far things move. We went outside and each student had a turn to see how far they could launch their marshmallow. We used a tape measure to record the results.

Push and pull....force....measurement.....what a fun way to teach these concepts!!
