Gelatin! It's hard to think of another food that is used as frequently on the dinner table as off. You can find it in all sorts of sweet foods, from ice cream, yogurt, and gummy bears, to marshmallows and yellow colorings for sodas. Off the table, it shows up in glues, photographic paper, playing cards, crepe paper, medicine capsules, hair gels, and professional lighting equipment. From the kitchen to the theater—what a range of uses! In this cooking and food science fair project, you'll…

Here is a riddle for you: what kind of rock grows? The answer is: rock candy! This delicious candy is actually crystallized sugar and you can "grow" it from a sugar-water solution. In this science fair project you'll learn how to grow your very own rock candy and determine if using seed crystals changes the growth rate of your sugar crystals.

When we get hot, we sweat. The physiological role of sweat is to cool us down. When the water evaporates, it removes energy from our bodies. This sort of evaporative cooling can also be used to cool homes, using what are referred to as swamp coolers. Evaporative cooling is also a potential source of energy waste in the kitchen because it increases the time it takes to heat water. In this chemistry science fair project, you will study how a variety of things cool down, whether for better or…

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?

Maple syrup is deliciously gooey and great on breakfast foods like pancakes and waffles. But it has another amazing property. It can be turned into maple candies with a range of textures, like sticky maple taffy or molded maple sugar candy. In this science fair project, you will investigate how the temperature that maple syrup is heated up to affects what type of maple syrup-based candies can be made.

What is the first thing you do when you wake up on a cold, frosty morning? Snuggle down deeper under the covers? Animals, like puppies and piglets, do not like being cold either, but they do not have hands or blankets to wrap themselves up. So when animals get chilled, they change their behavior and do things like huddle—they curl up close to other animals. In this mammalian biology science fair project, you will see just how much huddling can help reduce heat loss.

Have you ever left your bike outside in the rain? If so, you might have discovered unpleasant surprises afterwards—reddish-brown patches, known as rust, and your wheels, brakes, and gears might have stopped working so smoothly. In this chemistry science fair project, you'll learn why rust, a type of corrosion, is a serious problem. You'll also discover that not all rains are the same! Find out which ones can speed up the rusting process.

This physics project seems like it should have an easy answer. Instead, it turns out to be a great illustration of why it is important to base scientific conclusions on the outcome of controlled experiments. Things don't always turn out as we expect!

You know that water can exist in three separate phases: solid (ice), liquid (water), and vapor (steam). To change from one phase to another, you simply add (or remove) heat. When water boils, what happens to molecules (for example sugar or salt) that are dissolved in the water? Do they boil off too, or do they stay behind?
