Build an Electronic Piano with a Raspberry Pi

Science Fair Project Idea

Scientific Method

Lights and music make a great combination! Getting sound and lights to complement each other just right helps set the mood for everything from DJ parties and concerts, to theater shows, the circus, and ballet performances. You can put together your own lights and music show using a Raspberry Pi. Check out the video to see what this simple, but fun, project looks like. Once you have the basics down, you can keep tinkering with the circuit, the sounds, and the program to make fancier versions… 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

Building Personal Medicine Apps to Help Patients

Science Fair Project Idea

Engineering Design Process

Remembering to take medication or perform a test regularly, consistently, and at specific times can be difficult for elderly people with short-term memory loss, or teenagers absorbed in activities. With mobile devices becoming our constant companions, could a smartphone or tablet offer a solution? The Massachusetts Institute of Technology (MIT) has created a simple tool making it possible for anyone who has a computer and Internet access to create a reminder app. It is easy, quick, and… Read more

Buoyancy of Floating Cylinders

Science Fair Project Idea

Scientific Method

This science project presents an interesting puzzle. A disk of wood will float face-up; that is, with its circular cross-section parallel to the surface of the water. A long log of wood, however, floats on its side with the circular cross-section perpendicular to the surface of the water. If you think about it, disks and logs are both cylinders. Is there some intermediate length of cylinder that floats with the circular cross-section at a tilted angle? Try this experiment to find out! Read more

Your students might know that they can burn calories, but do they know what a calorie really is? In this fun lesson plan, your students will measure the energy content of food by literally burning it using a device called a calorimeter that they will design and build themselves. This will get your students thinking about the chemistry of energy transfer as well as good nutrition, and gives a whole new meaning to the phrase "burning calories!" Read more

NGSS Performance Expectations:

MS-PS3-3. Apply scientific principles to design, construct, and test a device that either minimizes or maximizes thermal energy transfer.
MS-PS3-4. Plan an investigation to determine the relationships among the energy transferred, the type of matter, the mass, and the change in the average kinetic energy of the particles as measured by the temperature of the sample.

Can Baking Soda Substitute for Baking Powder in a Recipe?

Science Fair Project Idea

Scientific Method

There's nothing quite like the smell of fresh-baked muffins for breakfast on a Saturday morning! If you're into baking, you might want to try this project, which will give you insight into some of the chemistry that's going on in your muffin batter. You'll get some practical knowledge about substituting ingredients. Who knows, it may even get you started on the path to some new culinary inventions! Read more

Can Beeswax Wraps Replace Plastic Wraps?

Science Fair Project Idea

Scientific Method

Do you ever use plastic wrap to cover a container? Did you know that it is made of plastic, which significantly contributes to the amount of waste in our landfills? There are many alternatives to plastic, and one popular product is beeswax wraps. Are beeswax wraps a suitable replacement for plastic wrap? Find out in this experiment! Read more

Can Cell Phones Survive a Drop Test?

Science Fair Project Idea

Engineering Design Process

Why do so many people use cell phone cases? Do cell phones really need the extra protection, or is it just because cases look fancy? In this engineering science project, you will test the durability of calculators instead of cell phones, find out if cases increase the durability of the device, and build some of your own cases that do!

Can Gaming Help You Score Better in School?

Science Fair Project Idea

Scientific Method

Can computer games be used to educate? Pick a game that incorporates educational material. There are a variety of educational computer games on the market in the areas of math, history, science, and language, as well as many simpler versions free on the Internet. Make up a test based on the subject area covered by the computer game. Have your volunteers take the test before and after playing the game. Does playing the computer game improve people's score on the test? Read more
