Here is an easy one.
Get a wooden plank. a sheet of glass (like a mirror or something) a sheet of metal (like a cookie tray).
Take some wooden blocks and stack them. Lay the plank so that one end is up on the blocks and the other is on the ground. Take another wooden block and slide it from the top to the bottom and measure how long it takes.
Then do the same thign for the glass and the metal.
What you are investigating is the coefficient of friction. You can even try wetting the items so see how water affects the coefficient of friction.
For details, you will have to do a little math to determing the friction forces, but it is all elementary physics.
Have fun!
