Free 3rd Grade Friction Worksheets

Friction teaches students that when two surfaces touch and slide against each other, a force is created that resists motion and slows things down. Third graders learn to compare the friction produced by different surface pairs, smooth vs. rough, wet vs. dry, and explain practical examples like why car brakes work or why it's hard to slide on carpet. The concept connects directly to engineering design challenges about reducing or increasing friction.

Friction is typically introduced in Grade 3 physical science as part of the forces and motion unit, alongside gravity and balanced and unbalanced forces. At ages 8-9, students are ready to investigate variables systematically, for example, testing which surface a toy car rolls farthest on, which makes friction an ideal hands-on investigation topic. It also pairs naturally with engineering design challenges.

Slide a book across different surfaces at home, tile, carpet, wood, and ask your child to rank them by friction using the worksheet's vocabulary. The comparison and prediction activities in the worksheets mirror these hands-on tests, so doing both together reinforces the concept from multiple angles. Physical science concepts like friction are among the easiest to explore at home without any special materials.
