Build a Gauss Rifle!

Science Fair Project Idea

Scientific Method

What can you do with magnets and ball bearings that makes a lot of noise? Why, build a magnetic linear accelerator, called a Gauss rifle, of course! Now, this magnetic accelerator is not a weapon, but a way for you to learn a lot more about physics concepts, like momentum. In this physics science project, you will investigate how far a ball bearing launched by a Gauss rifle will fly, depending on how many magnetic acceleration stages are in the setup and the ball bearing's initial velocity.… Read more

Here's a challenge: Try throwing a paper airplane by moving just your wrist (don't move your elbow or shoulder). It's hard, isn't it? How could you get a paper airplane to fly far if you can use only a short distance to launch it? Try this activity to find out! Read more

Build a Simple Walking Robot

Science Fair Project Idea

Engineering Design Process

Humans are pretty good at building vehicles with wheels, but building machines with legs that walk like us is a lot harder! In this engineering project you will build a simple robot that walks using a single motor. How fast can you make your robot go? Read more

What Conflicting Mental Tasks Reveal About Thinking: The Stroop Effect

Science Fair Project Idea

Scientific Method

Can you pat your head with one hand while you rub your stomach with the other? This science project idea is kind of like doing that, but this project can actually give you some insight into how your mind works. The task is to name colors. It sounds simple enough, but see what happens when color words get in the way. Read more

Soda bottle rockets are a safe and fun way to get into rocketry. If you want to discover what makes rockets fly, this is an activity for you. You can even add different features, like fins, a nose cone, and a parachute to find out how these alter the flight! Try it out! Read more

How to Make a Battery with Metal, Air, and Saltwater

Science Fair Project Idea

Scientific Method

Have you ever wondered how your cell phone or laptop keeps running once you unplug it? Sure, it is the battery that makes your portable electronics work, but how exactly does a battery do that, and from where does the electricity come? Generally, in a battery chemical energy is converted into electrical energy. In fact, many different types of batteries exist that are all based on a different set of chemical reactions. In this science project, you will explore a special battery variant called… Read more

With a few simple ingredients, you can create a "fire snake" that appears to grow out of nowhere in this fun experiment! Although it looks magical, no magic is involved—it is all because of a chemical reaction. Try it to find out how it works! Read more

Now You're Cooking! Building a Simple Solar Oven

Science Fair Project Idea

Scientific Method

Here is a project that uses direct solar power, gathering the sun's rays for heating/sterilizing water or cooking. It is a low-cost technology that seems to have everything going for it. Does it work? Can you find ways to improve it? Find out with this project. Read more

Marble Roller Coaster: How Much Height to Loop the Loop?

Science Fair Project Idea

Scientific Method

This is a really fun project even if you don't like going on roller coasters yourself. You'll build a roller coaster track for marbles using foam pipe insulation and masking tape, and see how much of an initial drop is required to get the marble to "loop the loop." It's a great way to learn about how stored energy (potential energy) is converted into the energy of motion (kinetic energy). Read more
