Build a Helping Hand

Science Fair Project Idea

Engineering Design Process

The human body is an impressive piece of machinery, and your hands are no exception. With some training, they can perform delicate and complex tasks like manipulating pens and tools to create art. At the same time, hands have the strength and durability to hold a person's own body weight up on steep rocks. Unfortunately, there is a rapidly growing demand for hand replacements. But fortunately, scientists have studied human anatomy and biology and created human-like hands used as artificial… Read more

Design and 3D-Print Your Own Robot!

Science Fair Project Idea

Engineering Design Process

Science Buddies has several fun robotics projects, like the Art Bot: Build a Wobbly Robot That Creates Art and Make a Robot Hand Using Drinking Straws, where you use arts and crafts materials to make part of a robot. Have you ever wanted to design a more-advanced, sturdier, or fancier looking robot? Then computer-aided design (CAD) and 3D printing might be for you; both are simpler than you think! The directions on this page will give you an introduction to these technologies so you can design… Read more

Build an Arduino Strobe Light for the Stroboscopic Effect

Science Fair Project Idea

Engineering Design Process

The Science Buddies project Build a Levitating Water Fountain with the Stroboscopic Effect shows you how to illuminate a dripping stream of water with a strobe light to make it look like the drops are hovering in mid-air. If you have not already, read the background section of that project and watch the following two videos. Make sure you understand frequency, period, and duty cycle before you proceed with this project. The project has you use a strobe light app on your phone. The advantage… Read more

Simple Circuit Logic with Switches: An Electric Puzzle

Science Fair Project Idea

Scientific Method

Here's a puzzle you may have heard before which you can build as a simple electric circuit. First, the puzzle: a farmer is traveling to market with his cat, a chicken and some corn. He has to cross a river, and the only way to cross is in a small boat which can hold the farmer and just one of the three items he has with him. The problem is, he has to be very careful about what he chooses to leave behind at any time. If the cat and chicken are left alone, the cat will eat the chicken. If… Read more

How Do You Get Heat from a Supercooled Solution? Explore the Chemistry Within Hand Warmers

Science Fair Project Idea

Scientific Method

You're at the high school football game and it's getting pretty chilly as the sun goes down. You're determined to keep cheering for your team, but your hands are freezing—have you ever tried hand warmers? The chemistry within these little packets is pretty cool. Hand warmers provide a unique and fun way to study the chemistry of crystal formation and heat generation. By pressing a button in a pouch, which contains a supercooled solution, you start a rapid exothermic (heat-producing)… Read more

Build an Obstacle-Avoiding Robot (BlueBot Project #4)

Science Fair Project Idea

Scientific Method

In the animal kingdom, many different critters use whiskers to help them find their way around in the dark, through murky waters, or even to help them hunt prey. Whiskers can be very useful when the animals cannot rely on sight. Did you know that you can also build a robot that uses "whiskers" to find its way around? This project will show you how to build a simple robot that uses whiskers as "bump sensors" to help the robot detect when it is about to bump into an obstacle, so it can turn… Read more

How to Make the Boldest, Brightest Tie-Dye!

Science Fair Project Idea

Scientific Method

The clothes you wear are made of fibers that come from many different sources. Some fabrics are made from natural fibers, and some from manufactured or totally synthetic fibers. In this science fair project, you will explore how different fiber types react with dye. Are you dye-ing to find out which works best? Read more

Build Statues That Come Alive When They See You

Science Fair Project Idea

Scientific Method

A simple circuit and a servo motor are all you need to turn any work of art into an interactive moving creation that is happy to see you. Light sensors see your shadow as you walk past your artwork and make a servo motor move back and forth. Waving arms? Turning heads? It is all up to you! Read more

Particles in the Mist: See Radioactive Particles Decay with Your Own Cloud Chamber!

Science Fair Project Idea

Scientific Method

Are you fascinated by radioactivity and the emission of particles caused by the disintegration of an atom? This science project enables you to observe safely a spectacular display of radioactive decay. Following the instructions in the Procedure, you will be able to isolate a safe radioactive source and build a cloud chamber to watch the radioactive decay. Then you will use your cloud chamber to discover if a plastic lid can shield you from this type of radioactive decay particles. Read more

Use a Calorimeter to Measure the Heat Capacity of Water

Science Fair Project Idea

Scientific Method

Along with its many other interesting properties, water has the ability to absorb a lot of heat energy, while only experiencing a relatively small change in temperature. One way this property affects us directly is that our bodies don't change temperature rapidly on hot or cold days, since we are made up of mostly water. In this chemistry-with-an-electronics-flair science fair project, you will determine how the temperature of a small volume of water changes as you add precise amounts of heat… Read more
