Make Your Own Shampoo and Test How It Performs!

Science Fair Project Idea

Scientific Method

Do you love it when your hair is nice and fresh? The key to keeping your hair nice and clean is to use a good shampoo. But with so many different products in the store, how do you know which one works best for you? In this science project, you will put a variety of shampoos to the test, including your own homemade organic shampoo recipes. Do you think these will perform better than a store-bought product?

Racial and Gender Bias in AI-Generated Images

Science Fair Project Idea

Scientific Method

If someone asks you to draw a picture of a doctor, lawyer, or engineer, what first pops into your mind? The race and gender of the person you imagine might be shaped by your personal life experiences, such as whether you have family members in those professions, or what representations of them you have seen on TV or online. What do you think will happen if you ask an artificial intelligence (AI) program to generate the picture instead? Will pictures generated by AI reflect the true real-world… Read more

Build a Simple Steerable Robot

Science Fair Project Idea

Engineering Design Process

Beginner robotics projects like the Art Bot and Bristlebots are fun, but the robots wobble around randomly and cannot steer. If you are ready for a robotics project that is a little more advanced (that does not require any programming), try this one out! You will build your own steerable robot with a wired remote control.

How Does the Number of Parachutes Affect Terminal Velocity?

Science Fair Project Idea

Scientific Method

Have you ever wondered how astronauts land safely back on Earth? Many spaceships use a small crew capsule with multiple large parachutes to bring the astronauts down to a gentle landing either on the ground or in the ocean. What happens if one or more of the parachutes fails to deploy? Can the astronauts still land safely? Find out as you explore the physics of falling with parachutes in this project. Read more

How Acidic Waters Make Rocks Disappear

Science Fair Project Idea

Scientific Method

If you have ever prepared a cup of coffee or tea with sugar, you have probably seen that the grains of sugar quickly dissolve and completely disappear in hot water. But sugar is not the only type of solid that can readily dissolve in a liquid. In fact, there are some types of rocks that can be dissolved by common liquids. It might be hard to imagine large, hard rocks being eaten away by some ordinary fluids, right? But it actually happens all the time! In this geology science project, you will… Read more

Build a Model Planetary Lander with micro:bit

Science Fair Project Idea

Engineering Design Process

How do you make a spacecraft land safely on the Moon or another planet like Mars? It probably helps to know how far away the ground is so you can deploy landing gear, activate a parachute, or fire thrusters to help slow down. In this project you will build your own "lander" vehicle with a sensor that can measure distance to the ground, allowing you to program outputs like blinking lights or an audible alarm. Read more

Moss is Boss: Using Plants to Determine Direction

Science Fair Project Idea

Scientific Method

Have you ever gone camping, looked up at the stars, and found the Big Dipper? Two stars in the dipper part of this constellation point to Polaris, the north star, which people have used for thousands of years to help them find their way. In this plant biology science fair project, you'll investigate whether plants, like moss, can help you find your way, too. Read more

The Physics of Artificial Gravity

Science Fair Project Idea

Scientific Method

How can we make space stations with artificial gravity a reality? In this science project, you will explore the physics of creating artificial gravity with circular motion. Read more

Can Biodegradable Materials Replace Plastic as Protective Food Packaging?

Science Fair Project Idea

Scientific Method

Many foods, such as fresh fruits, vegetables, or eggs, are packaged in plastic to protect them from damage during handling and transport. But is plastic the best choice? What if a more sustainable and biodegradable material could replace it? Researchers have begun exploring hydrogels—squishy materials that can hold a lot of water—as alternative packaging materials. In this science project, you will make your own hydrogels from gelatin and cornstarch and investigate what ratio of… Read more

What Modern Microbes Could Survive on Early Earth?

Science Fair Project Idea

Scientific Method

Have you ever wondered how life began on Earth? Or how life could get started on other planets? To help us better understand how life began, many scientists try to figure out what it would have been like to live on early Earth. In this science project, you will try to grow microscopic life that could have survived some of the harsh conditions of early Earth! Read more
