Science Fair Project Idea
thumbnail Earth is an amazing planet. It has everything that we need: food, shelter, and water. Sure, we need water to drink, but have you thought about using water to create energy? Moving water has a lot of energy and all we need to do is to harness it. Moving water made the Grand Canyon. That took a lot of energy! In this science fair project, you will demonstrate the power of water by converting the kinetic energy in moving water to mechanical energy, which will lift a small weight. Read more

thumbnail The movement of satellites is intriguing, but how do they orbit the way they do? Aerospace engineers run calculations and set up computer models to help them predict how satellites move in space, but in this astronomy science project, you will create a physical model with marbles, clay, and a cookie sheet to help you study how satellites move in space and learn from your observations.

thumbnail Can you imagine designing and building a space telescope the size of a tennis court? Believe it or not, that is someone's job! Engineers are hard at work on the James Webb Space Telescope, or JWST. This telescope has the potential to enable astronomers to see light from when the Universe was first formed. No one knows what amazing discoveries this might lead to. However, to make the telescope work properly, engineers have to overcome a lot of challenges. In this science project, you can… Read more

Science Fair Project Idea
thumbnail Playing basketball can be hard work. Players not only constantly run around the court, but just dribbling the basketball takes a lot of effort, too. Why is that? It has to do with how the basketball bounces. When the ball hits the court, its bounce actually loses momentum by transferring some of its energy into a different form. This means that to keep the ball bouncing, players must continually put more energy into the ball. In this sports science project, you will determine how high a… 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 "How do you frighten a grasshopper? And what does that have to do with light?" These are a couple of questions you're probably asking yourself after reading the title. Well, The Frightened Grasshopper Solar-Powered Bug is actually a toy grasshopper that vibrates when it is placed in sunlight or near a lightbulb. It stores up the energy from light, and converts it into motion. You will use this fun toy to explore how the brightness of the light affects the motion of the solar-powered insect. Read more

Science Fair Project Idea
thumbnail Just one sheet of paper can lead to a whole lot of fun. How? Paper planes! All you have to know is how to fold and you can have a simple plane in a matter of minutes! But what design should you use to build the best plane? In this aerodynamics science project, you will change the basic design of a paper plane and see how this affects its flight. Specifically, you will increase how much drag the plane experiences and see if this changes how far the paper plane flies. There is a lot of cool… Read more
