Show your fifth grade scientist how to create a siphon using two buckets, plastic tubing, and water. Watch her astonishment as the water travels uphill!

This science fair project compares the allelopathic affects of juglone, a chemical agent produced by the Black Walnut tree, on two plants.

In this popcorn experiment, students can explore how two things made out of the same material can have very different appearances and densities.

In this open-ended activity, students will be given a small quantity of three types of materials and asked to design a prototype for “something that will improve the school.”

Create a DIY Electromagnet! Using a 9v battery to create an electrical field around a nail, students explore electromagnetism in this cool science project idea.

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

Does electricity move better through thick wires or thin ones? kids will conduct this classic electricity experiment for this science fair project.

In this windmill model science project, you will build a windmill to learn about wheel-and-axle machines and how these simple machines are used to do work.

The objective of this science fair project is to examine the basic principles of air pressure using simple materials like a balloon, straw and string.

In this activity your child will make a coiling snake out of simple household materials, and also find out why they coil.

Kids learn about potential energy, and mechanical energy, and how to make power from water with one of our favorite renewable energy projects for kids.

This science fair project idea investigates if heat from direct sunlight is hotter than heat from reflected sunlight.

Science fair project that examines the behavior of water and gravel in creek beds and the formation of sedimentary rocks.

How do series and parallel circuits work, and which produces the brightest light in a light bulb? Construct both in this project and find out!

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?

Kids will love making sugar crystals in this sugar crystal science fair project which teaches important chemistry concepts like saturation and solubility.

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

This science fair project idea determines if the temperature of rubber effects how high it bounces.

Is your child a nature nut with an eye for creative, green-friendly projects? Introduce them to this amazing DIY bird feeder!

This science fair project idea attempts to train a worm to complete a simple maze in order to find out if worms can learn and remember.

Science isn't ho hum anymore when it involves building catapults to teach your fifth grader about projectile motion.

This science fair project idea provides evidence that air is everywhere and takes up space.
