Fill the Bucket
Place two buckets/bowls on opposite ends of your backyard. Fill one bucket with water and place a ping-pong/bouncy ball in the other. Have your child use a sponge to soak up water from one bucket, then run over and squeeze the water into the other bucket. Keep filling the buckets up until the ping-pong/bouncy ball floats out of the bucket! Who can fill their bucket the fastest?
Estimated Time: 30 minutes
Materials: Buckets/bowls, a sponge, water, and a ping-pong/bouncy ball
