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

Create clear sound shakers so your preschooler can observe and compare the different sounds that objects make!

Science fair project that compares the freezing temperature of salt water and freshwater in order to learn about supercooling and condensation nuclei.

Science fair project that determines the relationship between the temperature and the rate of cricket chirping. How many times do crickets chirp each minute?

In this science fair project, we'll use a liquid crystal thermometer to find out whether exercising makes a difference in people's temperature.

This science fair project idea quantifies the effect of weather- in this case temperature and humidity- on musical instruments.

Science fair project that tests the correlation between outdoor temperature or weather conditions and the number of visible stars at night.

Thermometers are how we measure temperature, and we've all heard the terms "centigrade" and "Fahrenheit" tossed around, but what do they really mean?

Science fair project that examines how temperature affects density and how density in turn affects the behavior of helium gas.

Check out this cool science fair project idea to explore non-chemical means of preserving fruits by using thermotherapy.

Compare air temperature with the infrared temperature from a reflecting surface at different times of the day, in shade and in sunlight.

Science fair project that determines the correlation between the ability of selected materials to conduct heat and a material's density.

Fudge is one of very few desserts people make at home that is actually crystalline. What happens when the fudge crystallizes at different temperatures?

How does bleach kill bacteria? Kids find out in this impressive bacteria science fair project by testing different concentrations on a safe strain of E. coli.

Have fun with bubbles and find out why there are bubbles in your tap water in this cool science fair project idea.

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!

This science fair project will help learners determine whether algae can be made to grow by feeding it supplementary carbon dioxide.

This science fair project determines what effect substances have on ice, and which of these products most effectively melts ice.

Help your first grade scientist learn about metamorphosis by observing the life cycle of some interesting creepy crawlies.

Determine whether magic salt is more effective at melting snow than regular salt. Pour one ounce of salt over the ice cubes, compare the melt downs.

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.

This project examines the affect of temperature on viscosity and surface tension of different liquids.

The objective of this science experiment is to evaluate the affects of high and low heat capacity on a material's heat retention ability.
