Science Fair Project Idea
You are looking under your bed for that video game you want to play, when you come across a real treasure—an open bag of potato chips that you forgot about! A crispy and salty potato chip is a tasty treat. But wait! This potato chip is not crisp and does not taste as great as it should. What happened? The chips have gone rancid! In this cooking and food science fair project, you will look into what factors turned your chips rancid. Read more

Science Fair Project Idea
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… Read more

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. Read more

Safety Use caution when handling glass jars or thermometers, as they can break or crack if dropped. Adult supervision is required when using the stove.
Science Fair Project Idea
Have you ever gotten a shock touching a doorknob after walking across a carpet? Static charge is responsible for that shock. Wouldn't it be cool to save up and store all of that charge in a homemade jar? It would almost be like storing lightning. This science project will show you how to do that. Read more

Safety Since this experiment deals with electricity, it is best to have an adult supervise. A mild to moderate electric shock is possible if care is not taken. Follow all directions as stated.
Science Fair Project Idea
A nice hot cup of tea sure can wake and warm you up in the morning. In this science fair project, you will investigate the chemistry of tea. The longer you steep a tea bag in hot water, the stronger the tea will be. But how does the strength of the tea change with longer brewing time? In this food science project, you will make a very simple electronic device to measure the strength of tea. The device will determine how strong the tea is by measuring the amount of light the tea absorbs. Read more

Science Fair Project Idea
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

- Less Details
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.

When something goes wrong, do you like to try to figure out why? Engineers do this all the time. They even have a fancy name for it: failure analysis. Understanding how different materials break is an important part of failure analysis. Here's a project with one approach to studying the way things break. Read more

Science Fair Project Idea
Have you ever mixed together salt and sand? It is fun to see how all of those tiny grains of salt and sand mix together! But what if you had to separate them out again? Do you have nightmares of tiny tweezers, a magnifying glass, and hours spent picking grains of salt and sand apart? Do not be afraid, there is another way! In this chemistry science project you will use the differences in solubility between salt and sand to find out the simple "solution" to this problem. Read more
