How well do you wash your hands? Do you just give them a quick rinse with water, or do you use soap? Do you wash the backs of your hands and in between your fingers? Good hand washing is one of the best ways to prevent the spread of germs and diseases like the flu and common cold. Try this activity to find out if there are hard-to-wash parts of your hands where germs might be hiding! Read more

Kimchi Chemistry

Science Fair Project Idea

Scientific Method

You're probably familiar with sauerkraut, a German dish of cabbage that is fermented in a brine made of its own juice and salt. Have you heard of another cabbage dish, called kimchi? Kimchi is a traditional fermented cabbage dish from Korea. Koreans eat kimchi year round, enjoying its spicy taste and the fact that it contains loads of vitamins B and C. In this cooking and food science fair project, you will make kimchi from scratch and investigate changes in pH and glucose as the kimchi… Read more

Make a Color Detector App to Help Colorblind People

Science Fair Project Idea

Engineering Design Process

Do you know anyone who is colorblind, or are you colorblind yourself? What if you could carry a device in your pocket that could identify colors for you? Many people already carry around the device they need to do this - a smartphone! Since phones have built-in cameras, you can make an app that uses the camera to identify colors. In this project you will use a program called MIT App Inventor that makes it easy for anyone, even with no programming experience, to design your own mobile app. Read more

Are you ready to move beyond paper circuits and squishy circuits? This is a great intermediate circuit project where you will build your own working night-light. And of course, you will have some fun decorating it! Read more

Make Your Own Shampoo and Test How It Performs!

Science Fair Project Idea

Scientific Method

Do you love it when your hair is nice and fresh? The key to keeping your hair nice and clean is to use a good shampoo. But with so many different products in the store, how do you know which one works best for you? In this science project, you will put a variety of shampoos to the test, including your own homemade organic shampoo recipes. Do you think these will perform better than a store-bought product? Read more

Measure the Frequency Response of a Paper Speaker

Science Fair Project Idea

Scientific Method

Can you build a working speaker out of paper? How does a speaker's ability to play low or high-pitched notes depend on its size? Explore the science of sound in this project as you build and test your own speakers in order to answer these questions! Read more

Measuring Antimicrobial Effectiveness with Zones of Inhibition

Science Fair Project Idea

Scientific Method

Have you heard that garlic powder is supposed to inhibit the growth of bacteria? Which do you think would make a better disinfectant: a solution of garlic powder or a solution of bleach? This project shows you a straightforward way to compare the effectiveness of different disinfectants (or other antimicrobial agents), by measuring zones of inhibition on a culture plate. Read more

Measuring Magnetic Fields

Science Fair Project Idea

Scientific Method

Have you ever noticed how magnets appear to have no effect on each other when they are far apart? Then, when you slowly move them closer together, you will start to feel a gentle pull until they suddenly snap together? How exactly does the strength of a magnet change with distance, and how would you measure it if you wanted to find out? In this project you will build a circuit that can measure the strength of a magnetic field and see how the field strength changes with distance. Read more

Password Security: How Easily Can Your Password Be Hacked?

Science Fair Project Idea

Scientific Method

We use passwords every day for our email and other computer accounts. How secure is the password that you use? How hard would it be for someone to guess your password? How hard is it to write a computer program to guess a password? You can see for yourself by writing a simple password guesser in the computer language Python. We will get you started with some ideas, a little sample code, and a few passwords for your computer program to try and guess. Read more

Rocket Science: How High Can You Send a Payload?

Science Fair Project Idea

Scientific Method

Rockets are definitively an engineering challenge. These amazing gravity-defying machines have lifted test material, people, and even animals into space. Feel like building one yourself? In this science project, you will transform a water bottle into an aerodynamic bottle rocket with two compartments, one for the fuel and one for a payload. You will then test how well it performs when lifting mass vertically up into the air. Ready, set, soar! Read more
