Tug o War

Today, we played a game of tug o war to explore how friction helps us to move. We played tug o war on the grass and in the school hall. We tried it outside on the grass (with shoes on) and with just socks on in the hall. We discovered that we moved more on the slippery hall fall, especially when we had socks on!

Grass and shoes = more friction.   Shiny floor and socks = less friction so we move more.
