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

Science fair project in which you will attempt to throw a ball the greatest horizontal distance possible by using different angles.

How does distance affect the spreading of light? Kids see diffraction and the inverse square law of light in action with this great science fair project idea.

Discover flight initiation distance as you play around in the park with this fun bird watching project!

Kids conduct a cool balloon rocket experiment in this fun science fair project idea. Does a greater volume of air mean a greater distance traveled?

This science fair project idea examines the distance a person travels on an average day and to relate that to an understanding of the size of the Earth.

What causes the seasons to change? Kids find out by modeling the earth's tilt using a globe, flashlight and graph paper in this cool science fair project idea.

This science fair project idea explores how much force is needed to move a lever at different distances from the fulcrum.

This science fair project idea investigates how optical distances change the apparent size of an object as seen through a magnifying lens.

Can a toy car determine the strength of a magnet? In this cool magnet science fair project, young scientists will learn how to measure the strength of a magnet.

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

How does a compass work? What's a magnetic field? Kids will build their own compass at home to find the answers in this great science fair project idea.

With this science fair idea, little scientists will gain valuable insights into the physics behind throwing a baseball.

The objective of this science fair project idea is to determine if sound travels best through the air, water or a solid.

Prove that the Earth is not flat. The objective of this science fair project is to measure the angle of the sun and calculate the circumference of the Earth.

In this fun science fair project, make two different scale models of our solar system using Astronomical Units and planets' relative size!

Science fair project which measures the shadow cast by a meter stick at various times in order to predict the circumference of the earth.

Science fair project about work and energy which uses a simple mathematical formula to predict how far a jar will roll down an incline.

Did you know your body is full of simple machines? This project looks at one of the third-class levers in the human body: your arm!

Demonstrate how static electricity can cause an object to move. It also examines just how an object affected by static electricity will move.

This light bulb science project includes step-by-step instructions for testing the heat from different light bulbs.

Kids make a paperclip perform an act of magnetic levitation and test how effective various materials are at magnetic shielding in this science fair project.

In this fun experiment, we'll find out how color affects heat absorption!

You've heard the expression "burn rubber" but do you know how heat affects rubber? Examine the impact of temperature on rubber in this fun science experiment.

What is a compound microscope? Kids find out by making one of their own in this cool science fair project.

What does a raindrop look like when it splashes on the ground? Is each raindrop unique like snowflakes? Find out how raindrop size varies in this experiment.

How greasy are your potato chips? Students will use a reliable method to quantify greasiness and compare different brands in this great science fair project.

Find out whether a longer airplane will fly farther or a wider paper airplane.

This science fair project idea develops an understanding through experimentation of which shapes are the most structurally strong.

Kids will create their own version of Richard Feynman's rubber band heat engine to learn about thermodynamics with this cool science fair project idea.
