Exploring Nanotechnology: Fold, Roll, & Stack Your Way to Super-Strong Materials

Science Fair Project Idea

Scientific Method

Advertisements for high-tech sports gear or the latest and greatest outdoor material promise lighter and stronger products every season. Is it a scam? How can engineers keep creating materials that are both lighter and stronger than anything known so far? The answer is in the nanoscale! Using nanotechnology, scientists can play around with the detailed structure of matter, leading to a whole new range of materials, some with amazing qualities. In this science project, you will get a glimpse… Read more

Build a Floating Maglev Train

Science Fair Project Idea

Scientific Method

How can you make a train without wheels? By using magnets! In this project you will build a magnetic levitation ("maglev" for short) train that floats above a magnetic track. How much weight can you add to the train before it sinks down and touches the track? Read more

How Does Speed Affect Orbiting Altitude of Satellites?

Science Fair Project Idea

Scientific Method

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.

Bioprinting: 3D Print with Living Cells! No 3D Printer Required.

Science Fair Project Idea

Scientific Method

Do you get excited about 3D printing technology? Do you like to think about other applications for this technology? 3D printing techniques can also be used with living cells, a method called 3D bioprinting. In this science project, you will explore 3D bioprinting a gelatinous substance with plant seeds. This process is similar to real 3D bioprinting techniques being explored to create tissues and organs. Read more

Ball Launcher Challenge

Science Fair Project Idea

Engineering Design Process

Try your hand at this engineering challenge. Can you build a "launcher" device to launch a ball as far as possible and a "receiver" to catch it? Building a receiver provides an extra twist to a traditional catapult project. Add to the challenge by using a limited set of materials to build your machine and calculate a score based on your throw distance and materials used. Read more

Why Does Fruit Turn Brown?

Science Fair Project Idea

Scientific Method

Have you ever wondered why apple slices turn brown once you cut them, or why a yellow banana gets dark spots over time? In this project you will find out why this happens, and how you can keep your apple slices looking fresh! Read more

Squishy Robot Simulator

Science Fair Project Idea

Scientific Method

What do an octopus, an elephant's trunk, and an earthworm have in common? They are all squishy, bendable and flexible because they do not have any bones inside. You might not typically think of robots as "squishy," but scientists are increasingly trying to create soft robots that look and move like animals. In this project you will use a "soft robot simulator" to design and race your own squishy robots. Can you come up with the fastest design? Read more

Art Bot: Build a Wobbly Robot That Creates Art

Science Fair Project Idea

Scientific Method

Do you like drawing or painting? What if you could build a robot that creates its own art? In this project, you will create your own Art Bot, a robot with markers for "legs" that wobbles across a piece of paper, creating drawings as it moves. You can then customize your robot to change how it draws. This is a beginner-level project with no robotics experience necessary, so if you want to try building your own robot, this is a great place to start! Read more

Mixing Mystery: Why Does Tumbling Sometimes Separate Mixtures?

Science Fair Project Idea

Scientific Method

What do sand and cereal have in common? They are both granular materials, which means they are made up of solid particles, but they can actually flow like liquid. When two granular materials with very different-sized particles are mixed, you can actually separate each type by putting them in a rotating device called a tumbler. In this science project, you will examine how common household granular materials behave when mixed together in a moving container Read more

Build a Circuit to Automatically Water Your Plants

Science Fair Project Idea

Engineering Design Process

Have you ever taken care of a plant? It can be tricky to get it right. You have to remember to water it regularly, and you also have to make sure to give it the right amount of water — not too much or too little. What if technology could help? In this engineering project, you will learn how to automate the entire process of watering a plant. Using a soil moisture sensor and a pump, you will build a circuit that will automatically detect when the soil is too dry, add water, and stop when… Read more
