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

This is a quick, easy science fair project that conveys the idea of density to preschool and early elementary children.

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

In this project combining nature, art, math, and science, children make rubbings of leaves then observe shapes and structures and sort the leaf images.

In this activity, children will let their imagination run wild as they design and build a new planet in the solar system.

In first grade, children are introduced to fractions. Here's a recipe that combines fraction practice with winter fun and lets kids actually paint the snow!

Here's a great early reading and science activity for curious children. Learn how to plant your child's name in seeds for a growing writing activity!

This weather spinner will improve observation skills by encouraging children to examine and track weather details and patterns.

Children learn the six parts of a plant...but do they really understand? Try this plant-themed meal plan to bring school science into the home.

Children are imaginative story-builders. Create a shoebox habitat with your child to put those budding creative instincts to good use.

In this science and engineering activity, children will explore types of tunnels and their purposes and then design and build a tunnel of their own.

This classic children's game-connecting two cups with a string-demonstrates sound's ability to travel through air vs through a solid.

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.
