Have you ever enjoyed watching something lift off into the air, like fireworks at a show or a spacecraft launching? It can be an amazing experience. It is thrilling to see something lift off against Earth's gravity. To launch a spacecraft, its rockets give it a strong push that is due to a chemical reaction. This means that every time you see a spacecraft launch, you are watching chemistry at work. In this activity you will get to blast an object into the air using two simple… Read more

Mars Terrain Exploration: A Hands-On Coding Investigation

Science Fair Project Idea

Scientific Method

Have you ever wondered what the surface of Mars is really like close up? Are you wondering what the Mars rovers get to see and experience? Some parts of Mars look smooth and sandy, whereas others are covered in rocks and rough terrain. In this project, you’ll step into the role of a planetary scientist and use real Mars rover images and Python code to detect, measure, and compare rocks across different types of Martian terrain. Here you’ll explore how image processing can help… Read more

Marble Roller Coaster: Converting Potential Energy to Kinetic Energy

Science Fair Project Idea

Scientific Method

If you'd like to investigate the physics of amusement park rides, then this project is for you. You'll build a roller coaster track for marbles using foam pipe insulation and masking tape, and see how much the marble's potential energy at the beginning of the track is converted to kinetic energy at various points along the track.

The egg-drop project is a classic and time-honored tradition in many science classes. The goal is usually to build a device that can protect an egg when dropped from a high location. This activity puts a twist on the classic project, motivated by real-world advances in space exploration. Can you build a reusable egg-drop lander that can survive repeated falls from the same height? Try this activity and find out Read more

Build a Miniature Self-Driving Car

Science Fair Project Idea

Engineering Design Process

How do self-driving cars stay on the road? How do vehicles with autonomous or driver-assist features automatically brake, steer around obstacles, or perform tasks like adaptive cruise control? Experiment with these behaviors and more in this science project as you build and program your own autonomous Arduino robot. Read more

How to Build an X-ray Machine

Science Fair Project Idea

Scientific Method

When you have your X-rays taken at the dentist's or doctor's office, do you ever wonder how the X-ray machine works? Or better yet, how you could make one yourself to use for experiments? This how-to guide provides detailed instructions for high school students and adult do-it-yourself (DIY) enthusiasts to construct and use a homemade X-ray machine safely. Read more

Build a Remotely Operated Vehicle (ROV) for Underwater Exploration

Science Fair Project Idea

Engineering Design Process

Have you ever wanted to explore cold or murky water? What about places where it could be dangerous or difficult for humans to swim? Remotely operated vehicles (ROVs) allow humans to take pictures, videos, and scientific samples of underwater life and habitats while safely operating the vehicle from a boat or from shore. In this project you will design and build your own small ROV that you can test in a bathtub, pool, or nearby body of water. Read more

Build an RC Boat

Science Fair Project Idea

Engineering Design Process

Do you like playing with radio-controlled (RC) toys like cars, planes, and boats? What if you could build and customize your own? In this engineering project, you will learn how to build your own RC boat using an Arduino and a plastic food storage container. Read more
