Space Radiation Protection

Science Fair Project Idea

Engineering Design Process

The radiation sources recommended in this experiment are low-dose radioactive sources and do not require a license to purchase; they are safe to work with as long as these common-sense safety tips are followed: Wear disposable gloves when handling any radioactive source. Never rub your eyes or mouth while you are handling the radioactive source. NEVER swallow any radioactive source and use protective glasses when bringing a source within a few inches of… 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

How to Make a Piano Sing

Science Fair Project Idea

Scientific Method

The renowned pianist Vladimir Horowitz once said, "The most important thing is to transform the piano from a percussive instrument into a singing instrument." In this project, you will learn how you can make piano strings sing using sympathetic vibrations. Find out which notes make another one sing the longest by measuring their sound intensities using a smartphone equipped with a sensor app. Read more

Wind Turbine Efficiency

Science Fair Project Idea

Scientific Method

Try different wind turbine/propeller (chord length, pitch) designs by making models from balsa wood. Connect the spinning axle to a DC motor and measure the voltage produced across a resistor to measure power output. Use fan as wind source. (Judge, 2004) Read more

Improving Focus for People with Neurodevelopmental Disorders

Science Fair Project Idea

Scientific Method

Have you ever wondered how you could help yourself or your classmates focus or perform better in class? Many students do! Some kids diagnosed with a neurodevelopmental disorder learn better in different ways, and easy changes while performing a task can make a huge difference to them. In this science project, you'll test if standing can significantly improve your performance and if this further improves performance for those who have neurodevelopmental disorders. Read more

Designing an AI Agent for Expense Tracking

Science Fair Project Idea

Engineering Design Process

Do you have a hard time keeping track of how much money you spend? What if you could automate the task somehow? In this project, you will explore how to use ChatGPT’s Agent mode to create an expense tracker spreadsheet. Read more

Can Visualization Improve Your Sports Performance?

Science Fair Project Idea

Scientific Method

Did you know that athletes use visualization of sports tasks to score the winning shot in sporting games? Check out how much visualization impacts your precision in sports with this science project idea. Read more

Under Pressure: Sand Under Lateral Compression

Science Fair Project Idea

Scientific Method

Here's a project that involves a different kind of sandbox than the ones you usually think of. This one has a moving wall inside, acting like a piston, to compress the sand. You can make layers using two different colors of sand, and then see what happens when you compress the layers with the piston. If you're handy with woodworking tools, this is a good project to give you a feel for the effects of geological forces that deform the Earth's crust. Read more

Household Water Usage

Science Fair Project Idea

Scientific Method

How much water do you use? Conserving water can do more than save your parents' money, it can also save freshwater ecosystems, wetlands, and watersheds. Some companies are trying to help fix the problem by making low flow faucets and showerheads. How well do they work? How much water can you save? Go to the hardware store to buy a few of the water saving products. Compare the amount of water that you run over a period of time to determine how much water you can save. Which water saving… Read more
