Ramps and racers
Set up a ramp with a book and a toy car. Have kids predict how far it rolls, then change one thing: raise the ramp, add a towel, add weight. They record each result and explain which force made the difference. It is a lab and a fair test all in one.
Why it works: going from real objects to pictures to symbols is a core recommendation of the U.S. Department of Education's elementary math guide.
