Friction Racing

In this activity, learners explore the unseen force of friction and how surfaces can slow moving objects at different rates. Learners will build ramps out of two types of materials and roll down a toy car (or similar object) to test which of surfaces has the least amount of resistance or friction. Activity includes step-by-step instructions with pictures, a video demonstrating the activity, a brief explanation of the science behind the activity, and a print out data chart to make predictions and record results.
