As part of our Science topic on Forces, Prep 3 have been investigating friction. With a little help from our Science Coordinator Mr Grant, we planned our own experiment to find out on which surface a toy car would roll best. We made our predictions, gathered our equipment, and got ready to roll…

The astro turf The rubber crumb The wet area The classroom carpet

We also tested a classroom table and the biscuit crumb surface where Early Years play.

Our results

We found that the surface with the most friction was the Astro turf because it was rough and spiky. The car only rolled 10 cm. The surface with the least friction was the classroom table where the car rolled a magnificent 85 cm! This was because it was smooth and had least bumps.
