Science Fair Project Idea

Scientific Method

Have you ever seen those cool wind tunnel pictures of cars with streams of smoke blowing over them? You do not need access to a wind tunnel to do a car aerodynamics science project! In this project you will use cheap, readily available materials—tape and yarn—to visualize airflow over a car. You will examine how you can affect the airflow over the car by making changes, like adding or removing accessories or making body modifications out of cardboard and duct tape. Maybe you can… Read more

The Role of Fats in Making a Delicious Pastry

Science Fair Project Idea

Scientific Method

Apple pie is one of America's traditional desserts. It can be enjoyed on its own or with a scoop of vanilla ice cream. The cool sweetness of the ice cream combines with the warm apples and flaky pastry to create a taste sensation. However, if the pastry that surrounds the apples is heavy or chewy then that can really affect how much you enjoy this treat. But how do you make a pastry that is light and flaky? In this cooking and food science fair project, you will find out by experimenting with… Read more

Can Video Games Be a Form of Exercise?

Science Fair Project Idea

Scientific Method

Have you ever played a video game that made you break a sweat? Or pant a little bit? The majority of video games are sedentary, meaning done in one position, but there is an increasing trend toward video games where the players are physically active. Do you think these video games can be considered exercise? This science fair project will help you find out! Read more

Which Liquid Works Best for Evaporative Cooling?

Science Fair Project Idea

Scientific Method

When we get hot, we sweat. Sweating helps 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. In some cases, these coolers may be more energy-efficient than traditional air conditioners. In this chemistry science fair project, you will find out which liquid works best for evaporative cooling.

Hands-on Shopping: More Likely to Buy if You Can Give It a Try?

Science Fair Project Idea

Scientific Method

Did you know that the average child sees 20,000 30-second TV commercials in just one year? That's a lot of encouragement to buy new toys, clothes, entertainment, and food. In this behavioral science fair project, you'll find out some other ways (besides commercials) that marketers use to try and get adults to buy products, like having them touch or hold an item. You'll find out if these methods work with kids, too, and if they increase how much people are willing to pay for a product. It's a… Read more

Build an Arduino Strobe Light for the Stroboscopic Effect

Science Fair Project Idea

Engineering Design Process

The Science Buddies project Build a Levitating Water Fountain with the Stroboscopic Effect shows you how to illuminate a dripping stream of water with a strobe light to make it look like the drops are hovering in mid-air. If you have not already, read the background section of that project and watch the following two videos. Make sure you understand frequency, period, and duty cycle before you proceed with this project. The project has you use a strobe light app on your phone. The advantage… Read more

Save a Life! Teach Hands-Only™ CPR

Science Fair Project Idea

Scientific Method

What would you do if you saw one of your friends lying on the floor, not breathing, possibly having a heart attack? Call 911? Start CPR (cardiopulmonary resuscitation)? Those would both be important things to do! But do you know CPR? Do your friends and family know CPR? Chances are, most of them don't. Even if they do know CPR, they might be hesitant to use their mouths to perform it. You can change that though. In this science project, you'll create a simple, interactive game that can teach… Read more

Use the Force! Push & Pull Robots With an Invisible Force

Science Fair Project Idea

Scientific Method

If you have seen any of the "Star Wars" movies, then you probably remember when Jedi knights like Luke Skywalker and Obi-Wan Kenobi used "The Force" to push, pull, and even throw objects — including some helpless battle droids. Have you ever wished you could do that in real life? In this robotics project, you will build and program a LEGO® robot that you can push and pull using an "invisible force" — almost like a real Jedi! We make no promise that you will be taking down the… Read more

Water from Air: Experimenting with Dew Traps

Science Fair Project Idea

Scientific Method

Most of us live in areas where sources of water exist nearby as oceans, rivers, lakes, ponds, streams, reservoirs, wells, or even underground streams. But in some places, like the desert, water is hard to find and a precious resource. In this environmental engineering science project, you will investigate one way that people living in arid regions can collect water inexpensively: dew traps. Read more

The Power of Heat Is Right Under Your Feet with Geothermal Energy

Science Fair Project Idea

Scientific Method

You might know that we are able to get renewable energy from the Sun, the wind, and water, but did you know we can get renewable energy from Earth itself? The temperature inside of Earth can reach 9,000°F—that kind of heat can be used to make a lot of energy here on the surface! This source of energy is called geothermal energy and it is all about taking advantage of the heat within Earth. So try this science fair project out and find out how to use the heat that lies beneath your… Read more
