Science fair project in which you will examine how crystals are formed by creating your own crystal using charcoal briquettes, salt, and ammonia.

This simple experiment serves as an introduction to the greenhouse effect.

Chlorine and chloramine are added to our tap water to kill harmful microorganisms. What is the best way to filter these disinfectants in your drinking water?

In this science fair project, we learn how air molecules move as a result of density, convection, and air currents.

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

Kids will learn how to measure the viscosity of liquids by making their own homemade viscometer in this great science fair project idea.

This fun science project helps to investigate how much water can a plant take up and release in a certain period of time through the process of transpiration.

In this cool project, create a lighted, scale model of the different layers of the Sun, including the core, radiation and convection zones, and photosphere.

This hands-on activity gives your child an opportunity to apply various strategies to solve a problem and to check if his answer makes sense.

Based on the concept of water's "freezing point," this activity entails the lowering of water's freezing point to chill ice cream!

Have your child observe, measure and record the amount of space objects occupy, and you'll have an inside space explorer on your hands in no time!

This science fair project idea explores whether factors such as temperature and concentration affect the pH of a solution.
