Go, Go Gravity Racers!!!



Our new science unit on force and motion has inspired us to make our very own gravity powered racers! We are developing vehicles that can travel down a ramp, powered only by gravity. The vehicles must travel at least 100 cm to be up for consideration for the pizza party prize!

As we build our vehicles, we are noticing some design flaws in our blueprints. We are brainstorming with our partners and talking with other groups to figure out ways to reduce friction and drag (air resistance), so that our cars can travel a greater distance. Some of us have discovered that mass has an important role in how far our car will travel after it leaves the inclined plane (ramp).

Check out some of our scientists hard at work!
