Splash! Floating Polka Dots Science Activity for Kids

Colorful floating polka dots make the perfect activity for kids to experiment with sinking and floating. We played outside in our water table because the weather permitted (hello spring!), but you could also play inside in a large container or bath tub. My kids always love it when we turn a science experiment into a water activity!

Polka Dot Splash

Pin me please! 🙂

Supplies:
Foam sheet circles (I found ours at the dollar store)
Water table/Large container or Bath tub
Small toys or blacks
Food coloring for water (optional)

Directions:

1. Fill up the water table and have child float the polka dots on the water.

2. Give children toys or blocks to balance on top of the polka dots. Have them see how many they can get on each polka dot before they splash and sink into the water.

Use different sized polka dots so children can see how surface are affects the ability to hold things and keep it floating.

My daughter observed that she could stack more foam blocks on the polka dots because they were lighter then our wooden blocks.

My son liked to hold the polka dots down to the bottom of our table then watch them float up. He also noticed that the polka dot would change color when it was under the water because we colored our water blue with food coloring. In the picture he is holding down a yellow circle. Cool right!
