To show how friction works in a fun way, you can do a simple experiment in class. This activity helps you see how friction changes with different surfaces and how much force you use.

Things You Need:

• A wooden block
• A spring scale (this measures force)
• Different surfaces (like sandpaper, smooth plastic, and carpet)
• A flat table or floor

Steps for the Experiment:

1. Get Ready: Start by putting the wooden block on one of the surfaces.
2. Measure the Force: Attach the spring scale to the block. Pull it gently and steadily until the block starts to move. Note down the highest number on the scale just before it starts to slide.
3. Do It Again: Try this on all the different surfaces. Make sure to pull the same way each time.
4. Talk About It: After you’re done, discuss how much force it took to move the block on each surface.

What You Might Notice:

• On smooth surfaces like plastic, it takes less force to move the block. This means there is low friction.
• On rough surfaces like sandpaper, it takes more force to move the block. This shows that there is high friction.

Wrap-Up:

This experiment helps you see and measure friction. It makes it easier to understand how friction affects movement in everyday life.
