Science Fair Project Idea
thumbnail Big, puffy, cotton-like clouds, and the bubbles in a pot of boiling water may not seem like they have much in common, but they do—both are formed by a heat-transfer process called convection. Warmed gases and liquids rise, while cooler ones fall, creating currents and mixing things up. Whether making processed foods in a factory or making plastic or metal parts, knowing how to mix up a big tank of hot and cold liquids or gases quickly is important. Engineers must rely on experimentation… Read more

thumbnail Everyone knows electricity can create heat, especially because our electrical appliances tend to warm up when turned on. But wouldn't it be cool to do the reverse — generate electricity from heat? In this science project, you will study why it happens, measure the effect, and then use the phenomenon to build your own device, a thermocouple thermometer, that will enable you to convert heat into electrical energy.

So you've just finished mowing the lawn on a hot summer day, and you'd like a cold, refreshing drink as a reward. You look in the fridge, and oops! it's empty. The sodas are still sitting in the cupboard, at room temperature. What's the fastest way to get that soda down to a cold, drinkable temperature with materials readily at hand? Read more

thumbnail Did you know that the color of your house could save money? Do this experiment to see which colors regulate temperature best in different environments. Then convince your parents to paint the house and save some money on their energy bill. Maybe they will be so happy they will also increase your allowance! Read more

thumbnail Nobody likes to get "the shivers"—that unpleasant, quivery, shaky feeling. What do you do when you feel chilled? Put on extra clothing? Drink something warm, like hot chocolate with marshmallows? Lie down on warm cement? Turn up the heat? People are quick to change their behavior when they sense that their body temperature is dropping. In this zoology science fair project, you'll learn that animals, like horses, don't like being cold either, so, just like people, they change their… Read more

Science Fair Project Idea
Expanding gases are everywhere, from the kitchen to the cosmos. You've tasted their pleasures every time you've eaten a slice of bread, bitten into a cookie, or sipped a glass of soda. In this chemistry science fair project, you'll capture a gas in a stretchy container you're probably pretty familiar with—a balloon. This will allow you to observe the gas expansion and contraction as the temperature changes. Read more

Science Fair Project Idea
thumbnail Along with its many other interesting properties, water has the ability to absorb a lot of heat energy, while only experiencing a relatively small change in temperature. One way this property affects us directly is that our bodies don't change temperature rapidly on hot or cold days, since we are made up of mostly water. In this chemistry-with-an-electronics-flair science fair project, you will determine how the temperature of a small volume of water changes as you add precise amounts of heat… Read more

Science Fair Project Idea
Ocean currents have a profound effect on the climates of the continents, especially those regions bordering on the ocean. The Gulf Stream makes northwest Europe much more temperate than any other region at the same latitude, and the California Current keeps Hawaii cooler than other land masses at the same latitude. In this ocean science fair project, you will model the behavior of these "rivers" of hot and cold water within the ocean to find out how temperature affects the currents' velocity. Read more

Science Fair Project Idea
thumbnail Objects that glow in the dark hold a special place in the imagination of both children and adults. The lights go out at night, but these odd things refuse to disappear. Where does the light come from? Do they work in any climate? In this science fair project, you will build an electronic device that measures the light given off by luminescent materials. The device will be used to study how temperature affects luminescence. Read more

Time Required Long (2-4 weeks)
Prerequisites A familiarity with basic chemistry is required. Also, some experience with electronics would be helpful. Although the circuit is fairly straightforward, especially if you use the kit, this is a DIY ("do-it-yourself") project that will call for some creative problem solving on your part.
Material Availability Any phosphorescent material will work for this project. If you want to use super-bright phosphorescent paints, they are available online. See the Materials & Equipment list for more information.
Cost High ($100 - $150)
Safety Use caution when using the drill or knife. Wear safety goggles when using the drill.
