Recently students in third grade designed and built marble roller coasters in order to better understand the concepts of motion. They explored the effects of friction, gravity and momentum as they designed, tested, redesigned and improved their constructions.

As part of their continued studies, they performed a science lab where they examined balance versus unbalanced forces. They discovered through experimentation that just because an object is not in motion does not mean that forces are not action upon it.
