Science Fair Project Idea
You might think that one sure-fire way to keep your computer safe from hackers is to disconnect it from the internet entirely. But did you know that even without internet, a computer can transmit data using light, sound, vibrations, or even heat? In this project, you will investigate how a spy or hacker can steal data from an "air-gapped" computer that has no internet connection. You can even use Google's Science Journal app to demonstrate how the data can be picked up by a nearby smartphone. Read more

If you like listening to music and making crafts, this is a great project for you. You will learn how to make a completely functional speaker that you can use to listen to real music...out of paper! Along the way, you will learn about the science behind how a speaker works. Speakers depend on magnets to create sound—does adding more magnets make the sound louder? Try this project to find out! This project is compatible with Google's Science Journal app, which allows you to collect data… Read more

Have you ever ridden on a carousel, or a merry-go-round, at an amusement park? On a carousel, you usually get to take a seat on a wooden horse or other animal that spins around and around as the carousel is turned on and powered by electricity. Another smaller type of carousel that people can have in their homes is a candle carousel, which is powered by heat from candles. In this science project, you will get to make your own candle carousel and investigate how the spinning speed of the… Read more

Do you think you could build a car powered by nothing but air? A balloon-powered car is pushed forward by air escaping from a balloon, and it is fun and easy to build with materials you already have around your house. Can you imagine how you would want your own balloon-powered car to look? Can you design a car that will travel as far as possible? You can even measure your car's speed using your smartphone and Google's Science Journal app. Get ready to grab some simple supplies to bring your… Read more

Practice makes you better at most things, and knowledge makes practice so much easier! Can you swirl a circular toy called a hula hoop around your waist or arm? Is it hard? What knowledge can you apply to find ways that make hula-hooping easier? Physics! Yes, physics will help you determine what makes one hula hoop a winner and another a flop. In this project, you will create your own hula hoops, spin them, and draw conclusions. The road will then be open to your becoming a hula hoop expert. If… Read more

Have you ever seen a chemical reaction that makes a solution change color? Probably. But what about a solution that changes color and then changes back, not only once, but many times? Sounds pretty exotic! Whereas most chemical reactions only move in one direction from reactants (starting chemicals) to products, in these rare oscillating reactions, the reaction products appear and disappear for a number of cycles. Because the products are colored, the solution appears alternately blue, then… Read more

Have you ever looked up at the stars at night and wondered how fast they were moving or how far away they were? By studying how the brightness of a star changes with distance, you can answer those questions. In this astronomy science project, you'll create a model of starlight and use Google's Science Journal app with your smartphone or tablet to discover the key relationship between brightness and distance.

Science Fair Project Idea
The iodine clock reaction is a favorite demonstration reaction in chemistry classes. Two clear liquids are mixed, resulting in another clear liquid. After a few seconds, the solution suddenly turns dark blue. The reaction is called a clock reaction because the amount of time that elapses before the solution turns blue depends on the concentrations of the starting chemicals. In this chemistry project, you will explore factors that affect the rate of the iodine clock reaction and can even record… Read more

You may have seen police investigators on TV spraying a crime scene with a liquid that glows blue if there is any blood present. Luminol is the chemical which causes the glowing. In this chemistry science fair project, you will investigate what factors make this interesting molecule "light up." Read more

Did you know that the United States jump rope record (as of 2017) for the greatest number of jumps in a minute is 372? That's more than six jumps a second! How close do you think you can get to that number? If you are going to try to break the record, it might be important to figure out how jump rope length affects your success. Try your hand at this skipping science fair project and jump-start your chances for a jump rope record. If you have a smartphone available, you can use it to measure… Read more
