Science Fair Project Idea

Scientific Method

Imagine how cool it would be to build a robot hand that could grasp a ball or pick up a toy. In this robotics engineering project, you will learn how to use drinking straws, sewing thread, and a little glue to make a remarkably lifelike and useful robot hand. What will you design your robot hand to do? Pick up a can? Move around a ping pong ball? It is up to you! With these starting instructions, you can design any type of hand. You will simulate human finger anatomy as the basis for a… Read more

Make a Spacecraft Motion Simulator!

Science Fair Project Idea

Engineering Design Process

How do you practice landing a spacecraft on another planet or docking it with a space station? With a spacecraft motion simulator here on Earth! In this engineering project, you will design and build your own cable-driven spacecraft motion simulator that lets you move a model spacecraft around in three-dimensional space. Read more

Make a "Whirlybird" from Paper

Science Fair Project Idea

Scientific Method

Have you ever seen a maple seed twirling as it falls through the air? In this project you will build something that behaves similarly called a whirlybird. Will your whirlybird be able to stay in the air as you add paper clips as weights? Try this project to find out! Read more

Make an Origami Robotic Gripper

Science Fair Project Idea

Engineering Design Process

Do you like making paper airplanes? What about origami animals? Have you ever thought about making a paper robot? In this engineering project, you will make a three-dimensional robotic gripper that starts out as a single flat sheet of paper! Try it out—see what objects you can pick up with the gripper, then see if you can improve the design. Read more

Make the Fastest Rubber Band Paddle Boat

Science Fair Project Idea

Engineering Design Process

Rubber band paddle boats are a fun bathtub or pool toy that you can build yourself. How do you make a boat that goes the fastest? Find out in this project as you build and test your own boat. Read more

Make Your Own Hot Air Balloon

Science Fair Project Idea

Scientific Method

Have you ever looked up into the sky and seen not a bird, not a plane, but a hot-air balloon? They are definitely amazing and fun to watch! Do you think they are all the same size? Does size affect how long the hot-air balloon can fly? In this science fair project, you will launch hot-air balloons, powered by a toaster, and see how the size of the balloon affects its flight.

Make Your Own pH Paper

Science Fair Project Idea

Scientific Method

This is a simple "kitchen chemistry" project about acid/base chemistry. Scientists measure the acidity or alkalinity of a solution using a logarithmic scale called the pH scale. In this project you'll learn about the pH scale, and you'll make your own pH indicator paper using a pH-sensitive dye that you'll extract from red cabbage. You can use your pH paper to measure the acidity/alkalinity of various household solutions. Read more

Make Your Own Wireless Alarm System

Science Fair Project Idea

Engineering Design Process

Have you ever wished you could have an alarm to prevent your little brother or sister from sneaking into your room? How about an alarm to prevent someone from stealing your favorite toy or from taking cookies out of the cookie jar? In this project you will learn how to program your own customized, wireless alarm systems to send you alerts about whatever you want! 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

Marble Machine

Science Fair Project Idea

Engineering Design Process

Put your engineering skills to the test to see if you can build a machine—powered by nothing but gravity—that will automatically sort out two different sizes of plastic spheres. That might seem like a strange task, but have you ever used a coin sorter to separate pennies, nickels, dimes, and quarters? How about using a sifter in the kitchen to separate fine grains of flour or sugar from bigger lumps? Machines that can automatically sort objects or particles of different sizes are… Read more
