In this hands-on design challenge your child will make their very own Rube Goldberg Machine.

This science fair project idea discovers if an artificial light source will yield the same plant health and growth rates as light from the sun.

In this science experiment, do tensile strength test on fishing line, a strand of hair, a rubber band, and any other materials you're curious about!

Do earthworms like moisture or darkness? Find out as we explore the relationship between earthworms and light.

In this science fair project, students make their own rain gauge to measure rainfall.

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

In this cool science experiment, learn about magnetism and poles, and test magnet strength to find out if two magnets are twice as strong as one.

Do you love to make Jell-O? Find out in this science fair project idea if it is possible to make Jell-O with just warm water.

What's a liquid? What's a solid? What better way to experiment than by turning a childhood favorite, ice cream, into a homemade science lesson!

Here's a science experiment that gives your kids a chance to see how fire needs oxygen to burn, with a little math and writing practice thrown in.

Why doesn't the ocean freeze? Students answer this question by simulating the chemical composition and temperature of arctic waters in their own home.

Brine shrimp usually live in saltwater. Investigate how salt concentration (salinity) affects the rate at which brine shrimp eggs hatch.

Why do ants like sugar? Do ants like artificial sweeteners too? Kids find out with this great inquiry-based science fair project.

In this cool engineering science fair project, kids learn how to build Hero's engine: an enlightening example of Newton's third law.

This science fair project idea explores which fruit molds the fastest.

In this science fair project, young children discover what happens when two fluids that have different densities get together.

In this fun science project, learn about what happens to cut fruit and experiment with how to stop apples from turning brown.

Learn the basic structure of a DNA strand, which is the double helix, how genes form together, and the resemblance DNA has to a twisted ladder. Create a model.

This science fair project idea creates a sedimentary rock and to investigate what takes place during the rock cycle.

It's not actually that hard to get energy from garbage! Kids learn how to make biogas in the form of methane with this cool and easy science fair project idea.

Help your fifth grader execute this experiment involving a lit candle (submerged in water!) to show him the wonders of heat energy transference.

The objective of this science project was to build a model of a volcano and observe reaction between different substances, including baking soda and vinegar.

Examine whether distilled water, spring water, or regular tap water yield faster plant growth.

In this cool science fair project idea, kids conduct the ruler drop test on volunteers to determine whether reaction time can be improved with practice.

Is there a relationship between caffeine and heart rate? Students will determine the effect of caffeine on heart rate in this fun science fair project.

The goal of this evaporation experiment is to learn about how different external conditions affect drying time.

This easy and inexpensive paper towel science project introduces kids to important physical concepts like cohesion, adhesion, and capillarity.
