By identifying, analyzing and interpreting patterns in the data they collect, students discover that friction, an invisible force, both helps and hinders things we do in our day to day lives. In this inquiry, students use the skills of predicting and planning a fair test to investigate how different solid surfaces affect the movement of an object on a ramp. Friction happens when two solid materials rub together, but it also happens when different forms of matter move past each other (e.g., a solid moving through a fluid such as air or water creates air resistance or water resistance). Friction is caused when two objects rub against each other. Or, you pedal your bike and the wheels spin wildly with no effort, but the bike goes nowhere because the tires will not grab the ground to pull you forward.įriction is the force that resists motion – it slows down or altogether stops motion. You try to stand up and your feet cannot grip the floor to push yourself up. ![]() You sit on a chair and you slide right off. Students use the skills of predicting and planning a fair test to investigate how different solid surfaces affect the movement of an object on a ramp.
