Introduce your child to the world of motion and physics with a bit of marble play inspired by Sir Isaac Newton!

Learn about the microclimate of your backyard by tracking rainfall, temperature, and observed weather with hand drawn charts and graphs.

What is elasticity? Students will investigate how this concept applies to bouncing ball physics by testing the bounces of balls made out of different materials.

Learn about sound physics and do a survey experiment to explore the difference between sound and noise in this science project.

In this free science fair project, learn how to separate salt from water using heat. A great science project for elementary school kids.

Science fair project examining barometric pressure, and how it can be used to predict the weather. How does atmospheric pressures relate to weather conditions?

Science fair project that examines condensation and the conditions needed in order for dew to form.

Get your sense of humor ready for this fun science experiment that demonstrates the fundamental physics of air pressure.

This homemade barometer allows your little scientist to contemplate and compare different air and weather conditions.

In this physics project, learn about the relationship between light intensity and distance using a laser pointer, flashlight, and graph paper!

Combine the science of physics with the fun of playing spy. Your young detective can make his own tiny looking glass. It's simple to make!

Here is a fun middle school science project on factors affecting solubility. Learn how dissolved solids can "crash out" to form crystals when conditions change.

In this project students experiment with making music using only glasses of water.

This project compares the strength of one, two, and three-ply toilet paper.

Make a spring collage with your child to get them outside and those creative juices flowing!

How does a kazoo, the strings of a guitar, or the speaker of a radio make sound? The purpose of this science fair project is to show how vibration makes sound.

This science fair project will help students learn about non-vascular plants, such as mosses.

In this science fair project, we'll use a liquid crystal thermometer to find out whether exercising makes a difference in people's temperature.

This fun experiment provides a concrete and visually striking illustration of photosynthesis.

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

In this science fair projects, students will grow out the bacteria that collect on air conditioner filters.

This science fair project explores how osmotic pressure forces water through the root up into the plant.

In this science fair project, students examine under what conditions individual plants release seeds and how far the seeds are released.

In this experiment you explore how tectonic plates move to create land and expand bodies of water.

In this science fair project, students use the streak test to tell minerals apart from each other.

This project explores whether plants can live and grow when "watered" with juice, soda, or milk.
