This project examines how different surface textures affect friction. By sliding objects over varied surfaces, students will learn how texture influences movement and resistance.
If the surface texture is rougher, then the friction will increase, causing objects to move more slowly or require more force to move.

Attach the smooth board to a flat surface using tape.
Place the wooden block on the smooth board.
Use the spring scale to pull the block and measure the force needed to move it.
Record the force measurement in the notebook.
Replace the smooth board surface with sandpaper.
Repeat the force measurement with different grits of sandpaper.
Record all measurements for each surface texture.
Compare the force needed for each texture.
Analyze how texture affects the frictional force.
Draw conclusions based on the data collected.
Rougher surfaces are expected to increase friction, requiring more force to move the block as compared to smoother surfaces.

Be cautious when handling sandpaper to avoid scrapes or cuts.
Provide a hands-on demonstration of the experiment.
Display force measurements in a comparative chart.
Explain how friction affects everyday movement.
Friction is the resistance that one surface or object encounters when moving over another.
Different textures can increase or decrease the resistance between surfaces, affecting movement.
Friction can be measured by the force needed to move an object over a surface, often using a spring scale.
