Make a periscope with milk cartons and mirrors! This preschool activity is great for playing secret agent and learning simple physics.

This project leads to an understanding that a whole may be built of smaller parts that fit and work together and provides an introduction to basic tools.

This science fair project introduces children to static electricity and the idea that electricity is more than lights and plugs.

Using a toy race car kids create a visual model of the Doppler Effect.

Checkerboard play challenges students to use spatial reasoning and computational thinking.

In this science fair project, young children discover what happens when two fluids that have different densities get together.

In this science fair experiment, children demonstrate the relationship between the amount of stuff and the amount of pressure in a closed system.

In this sound experiment children listen for differences as they tap on a bag of air, a bag of water, and a wooden block held up to their ears.

In this air pressure science experiment with a balloon and a jar, children will use heat to create a partial vacuum and suck a balloon into a jar.

This classic children's game demonstrates how sound travels through air vs. through a solid.

This project demonstrates the correspondence between the volume of water displaced by a submerged object and the volume of the object displacing it.

Children have a naturally inquisitive mind. Foster their curiosity with a walk through an autumn field or park to answer age-old “why” questions. As you walk with your child, you can encourage them to ask questions.
