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

This super fun science project, perfect for young children, combines crafts, dressing up as animals, outdoor play, and life science learning.

Stories change as you retell them. The objective of this science fair project is to demonstrate how information gets interpreted, distorted and changed.

Learn how different types of soil affect how animal tracks form in this experiment!

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

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

Why do plants wilt? Kids will learn to think critically about what environmental factors affect plants, and what plants need to survive.

In this science project, young children observe, record, and create collections of colors in their world and increase their powers of observation.
