How Does LED Brightness Vary with Current?

Science Fair Project Idea

Scientific Method

LEDs (light-emitting diodes) are electronic components that convert a portion of the electrical energy flowing through them into light. How does the intensity of the light produced vary with the current flowing through the LED? To find out, you'll build some simple circuits to vary the current flowing an LED. You'll also build a simple light-to-voltage converter circuit to measure LED output. 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

Strength in Numbers?

Science Fair Project Idea

Scientific Method

Ever try to tear a telephone book in half? Even though you can easily rip one or a few pages to shreds, the entire phone book has strength in numbers and holds together. This project is an introduction to measuring and comparing the strength of materials. Does spaghetti get extra strength if you bundle it together, or does strength simply increase proportionally with the number of strands? If you are interested in materials testing, get cracking!

Applying Hooke's Law: Make Your Own Spring Scale

Science Fair Project Idea

Scientific Method

Hooke's law says that the opposing force of a spring is directly proportional to the amount by which the spring is stretched. How accurately Hooke's law describe the behavior of real springs? Can springs be used to make accurate scales for weighing objects? Spring into action and find out for yourself with this project. Read more

Take a Hike: Train Your Robot Dog to Walk with a Virtual Leash

Science Fair Project Idea

Scientific Method

Have you ever walked a dog on a leash? Depending on how well-behaved the dog is, it can be very easy or very difficult. It would be great if you could tell your dog exactly how to behave, right? With that in mind, in this project you will build a robotic dog using a LEGO® Mindstorms® kit that you can teach to "walk" using the beam from a flashlight as a virtual leash. But your robot dog will not know how to walk on a leash on its own — you will have to "train" it, just as you… Read more

Write Your Own Calculator Program

Science Fair Project Idea

Engineering Design Process

When you need a calculator, what do you use? A physical calculator? An app on your phone? A web browser? What features does the calculator have? Does it just do basic arithmetic (addition, subtraction, multiplication, and division)? Can it do other mathematical functions, like square roots or exponents? Can you use parenthesis? Does it have a backspace button? That is a lot to consider for a seemingly very simple device or program! For a computer science project, can you write your own… Read more

Blocking RFID Readers from Reading your ID Card

Science Fair Project Idea

Scientific Method

If you've ever watched an adult pay for something by simply touching their credit card to a machine at a store, or you've done the same with a bus pass, you've seen an RFID tag in action. An RFID (Radio-Frequency IDentification) tag allows a card to be read by a computer from a short distance away. This is very convenient, but it also allows criminals to steal information about you. For instance, on the subway or the bus, someone standing next to you can use an RFID reader to access the data on… Read more

Engineer a Cell Phone Stand

Science Fair Project Idea

Engineering Design Process

Look around you. What types of objects do you see in the room? Furniture, lights, a computer, a fan, pencils, books, etc.? Where did they come from? Odds are you did not build them yourself. You or your parents probably bought them at a store. Before that, they were built in a factory somewhere. And even before that, they were probably designed by engineers. You might think of engineers when you think of complex machines like rockets or huge structures like bridges, but engineers also design… 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

Music for Martians: Build and Play a Theremin Instrument

Science Fair Project Idea

Scientific Method

Here is a riddle for you: name an instrument that you play with your hands but never actually touch. Have you guessed the answer? It is a theremin! This unusual instrument makes sound without anyone touching it. How does a theremin work? It has an antenna that can detect the player's hand nearby, and as they move their hand around the theremin, the sound it makes changes based on the hand's position. In this music science project, you will get to use your own mini theremin to investigate how… Read more
