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

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

In this cool experiment, learn how to find specific gravity of minerals using liquids of different densities to see which substances and items sink and float.

In this physics project, you'll learn how to find the maximum height of a projectile using some math and trigonometry.

This experiment will explore the possibility of creating an infinite object by hand.

In this science fair project on the relationship between distance and time, kids explore the behavior of gravitational acceleration through direct observation.

This science fair project idea investigates how the shape of an object affects drag.

In this project, all you need is a protractor to learn how to use the altitude of Polaris to find latitude on Earth. Polaris is also known as the North Star.

Demonstrate the relationship between mass, volume and density. Measure displaced water, and weigh object to calculate mass and density.

This science fair project idea shows how a vibrating object transfers energy to whatever it touches.

This project examines Newton's First and Second Laws of Motion with a bicycle and water balloons.

Science fair project that uses iodine vapors to develop latent fingerprints on a non-porous object.

This science fair project idea explores if objects dropped from a high distance will equal a greater impact force than the object dropped from a low distance.

This science fair project idea determines if the size of the parachute will change the rate at which an object falls.

Demonstrate and explain holographic technology. Determine if a holographic image of a magnifier still magnifies the object beneath it. Explain the effect.

This science fair project idea investigates which objects float and sink in honey, water, and oil.

In this simple circular motion experiment, you'll observe tangential velocity and learn about how acceleration and centripetal force affect an object.

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

Find out whether matching resonant frequencies can cause objects to shatter.

Determine how different measurements of the same object might yield different values. Provide as many reasons that you can think of.

This science fair project idea discovers whether there are some objects that do not fall at a constant rate.

This science fair project idea explores if the length of the string that an object is suspended on has an effect on how fast or slow it swings.

Formulate a hypothesis and use the scientific method to determine the guess what is hidden in a box. Test abilities of volunteers, without opening box.

Check out this fun leaf chromatography science fair project idea for middle school students and discover the hidden pigments in leaves.

The buoyant force of water explains why some objects float in water. But why do some objects sink? Find out in this physics experiment and learn about density.

Do heavier objects fall faster than lighter ones? Students learn the answer by watching the effect gravity in a vacuum has on a coin and a feather.

Investigate the different ways in which objects and organisms can be classified, create your own. then have volunteers classify using their own systems.

Explore convex and concave objects and how they reflect light.

Find the North Star, and measure your latitude! The purpose of this science fair project is to find latitude and learn about geographic locations.

Find out whether putting something on top of a plant will inhibit its growth.
