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 project children discover, identify, and sort seeds from a variety of fruits and vegetables

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

This engaging project encourages young children to practice and refine the important scientific skills of sorting and classification.

This project is a vivid, concrete introduction to the basic but important idea that plants need sunlight and water to grow.

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.

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.

Wiggly worms are known for staying buried in the soil, but how does that affect plants? Are earthworms and plant growth related?

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

Study the life cycle of the common blowfly as it relates to forensic investigation. Record the first time you see flies, maggots, and eggs.

The objective of this science fair project is to examine the effects of temperature on salt and water solutions, as they form crystals over time.

With this cool floating rocks project, your child will get some hands-on experience with buoyancy and learn why certain rocks like pumice are able to float.

This science experiment has students test whether a snail moves faster on concrete or dirt.

Uh-oh! Is that a pill sitting on the counter or a piece of candy?

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

This experiment challenges students to forecast the weather based on the surrounding areas' weather.
