Kids will learn how to make a thermometer to to explore liquid density in this great science fair project. Which liquids are affected by temperature the most?

Do plants breathe? Not exactly. They do respire though! This activity will help your child with see that plants are producing the oxygen we need to survive.

This project determines whether Styrofoam, paper, or plastic cups are best for preventing ice from melting.

Most people assume that cold water freezes more quickly, but could that be false? Does hot water freeze faster than cold water? Let's find out!

When you rub a balloon on your head, your hair stands up; but is that true for everyone? Does hair color affect static electricity?

This science fair project looks one of the most important factors affecting seed germination: water. A fun and easy plant biology experiment for 3rd graders.

The goal of this golf science fair science fair project is to determine whether the temperature of a golf ball affects its elasticity and its rebound.

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.

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

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

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

The next time you've got a restless second grade earth scientist on your hands, use this experiment to demonstrate crystals and make a tasty treat, too!

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

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

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

Why does honey crystallize? This science fair project project answers this question and identifies the variable that makes this sweet solute crystallize faster.

Here is a fun middle school science project on factors affecting solubility. Learn how dissolved solids can "crash out" to form crystals when conditions change.

How does frost form? How fast does it form? Do this simple science project using a plastic glass, rock salt and some water to learn about deposition.

Your child can turn cookie dough into a big pile of colorful painted fall leaves ready for eating!

Making decorative pottery is a great way to experiment with making patterns and texture on a traditionally smooth surface.

This experiment uses a yeast solution, liquid detergent, and hydrogen peroxide to produce an exciting reaction like no other!

This simple heat transfer experiment is a great introduction to the concepts of heat transfer and conduction.

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.

Is horse manure a possible energy source in a crisis? Use calorimetry to find out how much energy horse manure can produce in this science fair project.

Science fair project which simulates the global conveyor belts on a small scale, and observes the effects of wind, density and temperature on water movement.
