What Sugar And Tea Does a Kombucha Biofilm Prefer?

Science Fair Project Idea

Scientific Method

You may have seen kombucha at the grocery store marketed as a healthy food choice. Did you know this drink is made with a special biofilm that ferments sugar into the tangy, fizzy drink? How does it do that? In this experiment, you'll learn how to make your own kombucha from a biofilm and what tea or sugar substrates you can change! Read more

Make an Automatic Evaporative Cooling System

Science Fair Project Idea

Engineering Design Process

You probably know that sweat helps cool your skin on a hot day because of evaporation. But do you think you can use evaporation to cool a building? Evaporative cooling systems could provide a more environmentally-friendly alternative to traditional air conditioning. In this engineering project you will build and try to optimize your own model evaporative cooling system. Read more

Measuring the Speed of 'Light' with a Microwave Oven

Science Fair Project Idea

Scientific Method

Did you know that you can measure the speed of light using a microwave oven, some egg white, and a ruler? Find out how with this cool kitchen science project thanks to Mr. Nick Hood, a science teacher in Fife, Scotland. Read more

Motorized Arduino Cable-Driven Spacecraft Motion Simulator

Science Fair Project Idea

Engineering Design Process

How do you practice docking a spacecraft with the International Space Station or landing on Mars? With a room-sized cable-driven spacecraft motion simulator! In this project, you will build your own miniature, motorized version of a full-sized motion simulator scientists are developing that can move model spacecraft around in a controlled manner.

Tracking COVID-19's Genomic and Clinical Evolution

Science Fair Project Idea

Scientific Method

Over time, viruses evolve. Their evolution is influenced by both neutral drift, the natural mutation rate of the virus, and selective pressure from the hosts' immune systems. Scientists study a virus's genomic evolution—the changes at the nucleotide and amino acid level—to better understand how the virus is spreading and the clinical implications. You can use public databases and tools to do the same type of tracking and analysis of COVID-19 that scientists around the world do. … Read more

Build a Voice-Controlled Lamp

Science Fair Project Idea

Engineering Design Process

"Alexa, turn on the lights!" Sometimes it is easy to take the technology around us for granted. But have you ever wondered how a smart speaker like an Amazon Echo® knows what you are saying and how it can control lights and appliances in your home? It can seem like magic if you buy a device that just works when you open the box. In this project, you will learn how it works. You will build your own smart home device to control an appliance with voice commands using an Arduino®. Get… Read more

Bristlebot Shape and Motion Tracking

Science Fair Project Idea

Scientific Method

Bristlebots are tiny little robots with no "brain." They are powered by vibrations and move around randomly. Even if there is no brain, can you still influence how they move by changing their design? Find out in this fun robotics project! Read more

Measuring Sugar Content of a Liquid with a Laser Pointer

Science Fair Project Idea

Scientific Method

Did you know that you can figure out how much sugar is in a liquid without ever tasting it? In this science fair project, you will learn how to measure the concentration of sugar dissolved in a liquid by using a laser pointer, a hollow prism, and some physics. You will discover how refraction, or the bending of light, is the key to measuring the sugar content of a liquid with a laser pointer. 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

What Makes a Team's Winning Percentage Deviate from the Pythagorean Relationship?

Science Fair Project Idea

Scientific Method

What makes a winning team? Getting all the best players? Good coaches? Good chemistry? This project will show you how you can use math to help you test your hypothesis about what makes a winning team. The Pythagorean relationship is a fundamental one in sports: it correctly predicts the records of 98% of all teams. But in 2% of cases, it fails. Why does it fail? Find teams that deviated substantially from their expected Pythagorean record (this information is available for baseball teams… Read more
