Gears-Go-Round!

Science Fair Project Idea

Scientific Method

Music boxes, bicycles, and clocks all have one thing in common: GEARS! You might say that gears make the world turn, since they are in so many mechanical instruments. How do they work and how do you know which gears to use? Find out in this simple experiment. Read more

Design Your Own Video Game with a Raspberry Pi

Science Fair Project Idea

Scientific Method

Do you play video games on a console or smartphone? Have you ever wished you had the power to change how a game worked, or even to create your very own game? This project will show you how to make your very own video game and controller using a Raspberry Pi. Check out the video to see what this simple, but fun, project looks like. Of course, you can design the looks and gameplay of your game any way you like! IMPORTANT: The instructions for this project were originally written using Scratch 2… Read more

Build a Reed Switch Motor

Science Fair Project Idea

Scientific Method

Motors are used in many things you find around your house, like your refrigerator, coffee maker, and even a lawn mower. In this electronics science fair project, you will get to build a simple motor, using a kit, and then test how the number of batteries (amount of voltage) used to power the motor affects its performance.

Game of Life

Science Fair Project Idea

Scientific Method

The Game of Life is the invention of the mathematician John Conway. It is a cellular automaton, consisting of a grid of squares that turn "on" or "off" depending on simple mathematical rules that involve neighboring squares. Depending on how the grid is first set up (i.e., the initial conditions), various interesting patterns appear. Can you write a Game of Life program in a programming language of your choice? If you are new to programming, check out these resources from the Raspberry Pi… Read more

Can a Toilet Paper Tube Support Your Weight?

Science Fair Project Idea

Scientific Method

Here's a fun project idea to learn about compression forces. For this experiment you'll need some empty toilet paper tubes, masking tape, sand (or table salt), pebbles (or marbles), a funnel, a cardboard box, and a sturdy chair to help you balance while testing the column. Seal one end of the tube with masking tape. Use the funnel to fill the tube with sand (or salt). Seal the other end with tape. Place the tube on end inside the paper box. Place the chair with its back to the box and hold… Read more

Use Sewable Circuits to Make Cool Costumes and Accessories

Science Fair Project Idea

Engineering Design Process

Do you want to add color-changing lights to your own clothing, costume, or fashion accessory? What about making the lights flash, or adding sensors to make them automatically react to things like temperature or motion? You can do it all with sewable circuits, also called wearable electronics, that let you sew circuit parts directly into fabric. You can make anything from a basic circuit with a few LEDs up to a programmable, Arduino-compatible circuit with multiple sensor inputs and multiple… Read more

Is a Deleted File Really Gone?

Science Fair Project Idea

Scientific Method

When you delete a file, by accident or on purpose, is the information really gone? Can you get it back? If you accidentally deleted your five-page report for school, you may be hoping it is not really gone. On the other hand, if you do not want someone to get their hands on the goofy and unflattering pictures you and your best friend took while staying up late the other night, you probably hope the files you deleted are gone for good! Computer experts are often asked about file recovery.… Read more

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

Squishy Robot Simulator: Physics Settings

Science Fair Project Idea

Scientific Method

In our introductory VoxCAD project, we provided you with a template file that included default material properties and physics simulation settings. These settings include friction, gravity, and temperature — all of which can drastically change how fast your robots move. However, we did not explain what exactly all these physics simulation settings meant, or how to change them. You can access the physics settings through the Physics Settings tab after entering the Physics Sandbox mode, as… Read more

Pop Goes the Metal: How Temperature Affects Snap Time of a Jumping Disc

Science Fair Project Idea

Scientific Method

Jumping discs can be a fun toy to play with, and with their sudden POP!, they can even be a good way to startle people who have never heard them before. Jumping discs use a neat trick to jump. They are made of two different types of metal, and these metals expand when they heat up (or shrink when they cool down), but not by exactly the same amount. In this science project you will explore how temperature affects the reactions of your jumping discs— and how to get the timing right if you… Read more
