Sink or Float Worksheet | Kindergarten Science Experiment for Kids

This sink or float worksheet kindergarten is a science experiment for kids activity that builds prediction and observation skills. Children look at pictures of objects (like an apple, stone, leaf, coin, and toy boat) and guess whether each one will sink or float, then circle the correct choice.

A bonus coloring step makes it extra fun: kids color the floating items blue (or follow the worksheet’s color key). Perfect for kindergarten science centers, water play lessons, STEM time, morning work, or home learning. Helps children explore materials, weight, and buoyancy in a simple way.
