Happy or Sad? Use Artificial Intelligence to Classify Faces

Science Fair Project Idea

Engineering Design Process

Do you think artificial intelligence (AI) is too complex to use? Think again! In this project, you will use AI to teach a web-based tool to classify happy and sad faces, or other objects, poses, or sounds. This experiment requires no coding skills; instead, you will need curiosity, creativity, and a critical eye. Why not give it a try yourself? Read more

Are Your Eyes Playing Tricks on You? Discover the Science Behind Afterimages!

Science Fair Project Idea

Scientific Method

Yogi Berra said "You can observe a lot by just watching." In this human biology science fair project, you will observe how your eyes perceive color by watching afterimages. Afterimages are the images you see after staring at an object for several seconds and then looking away. You will also learn how different cone cells in your retina respond to different colors.

2022 Paper Ball Run Challenge

Science Fair Project Idea

Engineering Design Process

In this engineering challenge, you will build a ball run from paper and tape, but there's a twist! You want to make your ball run as slow as possible. How long can you make it take for the ball to get from the entrance to the exit? You can see how other students have tackled this and other annual Science Buddies Engineering Challenges. Read more

What is the Most Effective Treatment for Whitefly Infestations on Plants?

Science Fair Project Idea

Scientific Method

Whiteflies are a group of closely related insect species whose larvae live on plants. Like aphids, they suck nutrients from the plant's circulatory system. What is the most effective method for fighting a whitefly infestation in your garden? This project has some ideas for you to try. Read more

Rusting Out: How Acids Affect the Rate of Corrosion

Science Fair Project Idea

Scientific Method

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. Read more

Can Every Part of a Plant Regrow?

Science Fair Project Idea

Scientific Method

Have you ever picked a flower and tried to make it stay alive in a cup of water? How long does that last? Do some flowers last longer than others? Why do you think that is? In this experiment, you will compare different plants to see which ones can regrow or regenerate after damage and learn why some plants are better at it than others. Read more

Making It Shipshape: Hull Design and Hydrodynamics

Science Fair Project Idea

Scientific Method

Sailboats, tugboats, barges, ocean liners, submarines are all different boats with different shapes. How does the shape of a boat's hull affect how easily it moves through the water? This project shows you how you can investigate this question using a homemade water trough and model boat hulls. Read more

Green Technology: Build an Electronic Soil Moisture Sensor to Conserve Water

Science Fair Project Idea

Engineering Design Process

Water is a valuable resource, and water shortages are a serious problem in many parts of the world. The problem can be made worse by people who waste water; for example, by watering a garden or using sprinklers on their lawn (or a farmer taking care of an entire field) when it has rained recently or the soil is already moist. How can you help conserve water and prevent such waste? One way is to build an electronic soil moisture sensor. This project will show you how to build a circuit that… Read more

Extracting Onion DNA

Science Fair Project Idea

Scientific Method

In this project, you'll learn how to isolate DNA from onion cells, separating it from other cellular components in a manner that still preserves its structure and sequence. In the end, you'll have enough DNA to see with the unaided eye, and you'll be able to spool it to demonstrate its strand-like structure. Read more

Ping Pong Pickup Challenge

Science Fair Project Idea

Engineering Design Process

In this engineering challenge, you will build a device that can pick up a ping pong ball from a distance and return it to a start line. The farther away the ball is, and the fewer materials you use to build your device, the higher your score. You can see how other students have tackled this and other annual Science Buddies Engineering Challenges. Read more
