This project examines what types of objects burn and which burn faster and cleaner.

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

Experiment about connection of senses of taste and smell. Using blindfold and noseplugs, administer blind taste test. Analyze results and organize data.

There are hundreds of properties in rocks which you can describe, so get your geology goggles on and get ready to rock your child's science skills.

This science fair project idea explores whether boiling and freezing water will have an effect on how much it weighs.

Do different types of oil mix or stack? Find out in this science fair project idea!

Determine which kind of rock (igneous, sedimentary, metamorphic) has the greatest reservoir capacity, which is the ability to hold the most oil and natural gas.

Challenge your learner to design and build a city of their own in this creative engineering activity.

This Mother's Day, mix in some fifth grade science learning to create this fabulous fudge!

Teach your child how butter is created by shaking up cream the old-fashioned way.

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

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

This project uses science and art to help students learn and teach others about Earth's endangered and extinct species.

Glass is see-through, but usually you can still see that it is there. In this experiment, we use baby oil to make glass go completely invisible.

Here is a nifty science experiment using Epsom salts to make "frost" appear on a piece of glass.

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

In this science experiment, observe convection currents forming and learn about how heat energy moves in liquids from hot to cooler areas through convection.

A simple science experiment exploring the physics of water pressure that's been amazing people since Medieval times.

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

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

This science project has students study a group of volunteer liars actively lying to study the behavior of a lie. Students see if they can figure out the truth.

This science fair project idea experiments with spinning color wheels and optical illusions.
