Model Car Design Challenge (Girl Scout Troop)

When engineers design something new, they need to think about forces like gravity and friction. Friction is a force that slows and stops moving objects. Without friction, any object that was pushed or pulled would keep moving forever. Build a model car out of GoldieBlox and test the friction of your car on different surfaces to prepare for a Troop Car Chase!
