Did you know that gears are all around you? You can find them in wind-up toys, bicycles, carousels, cars and trucks, cranes, drills, wind turbines, analog watches, and so forth! If you've looked closely at a moving bicycle, you have seen gears at work. Are you curious about their purpose? In this activity you will use candy to make gears and explore why they are so versatile. Read more

Gears-Go-Round!

Science Fair Project Idea

Scientific Method

Music boxes, bicycles, and clocks all have one thing in common: GEARS! You might say that gears make the world turn, since they are in so many mechanical instruments. How do they work and how do you know which gears to use? Find out in this simple experiment. Read more

Generate Recipes from YouTube Videos with AI

Science Fair Project Idea

Engineering Design Process

This project explores how large language models (LLMs) can generate recipes from YouTube cooking videos. In this science project, you will learn how LLMs interpret language and how prompt design can affect results. Read more

Genetically Engineer Yeast to be Fluorescent

Science Fair Project Idea

Scientific Method

Can you imagine a glowing loaf of bread? You might not be able to make the whole loaf glow, but you can get baker's yeast to fluoresce! The way to do this is to modify the genetic information of the yeast organism. The technology that is used to do this is called genetic engineering. With genetic engineering, you can insert a fluorescent protein gene from a jellyfish into yeast cells, so they start glowing under blue light! Do this project to see for yourself! Read more

Genetically Modified Foods

Science Fair Project Idea

Scientific Method

Genetically modified organisms (GMOs) are organisms whose DNA have been manipulated to give them new traits. In genetically modified (GM) food crops traits like resistance to drought or pesticide might be added, or the crop may have been made more nutritious, or the taste may be altered to give you something like the impossible burger. Are there GMOs in your favorite foods? Many countries have implemented or are in the process of implementing GMO labeling on foods, but with a little bit of… Read more

Germ Invasion

Science Fair Project Idea

Scientific Method

Microbes are everywhere in our environment, but for the most part they escape our notice. This project shows you how to safely culture and study common bacteria from your everyday surroundings. Read more

Getting a Bang Out of Breath Spray: Studying the Chemistry and Physics of a Small Explosion

Science Fair Project Idea

Scientific Method

Hold onto your hats! In this science fair project, you will make a device that sends a film canister across the room with a small chemical explosion. The energy for the explosion is derived from the combustion of ethanol. You will determine the launch velocity of the canister, as well as devise ways to study changes in gas pressure and volume due to the explosion. This science fair project is sure to take your breath away! Read more

Do you ever wonder why we perform tasks in a particular way? Very often, we learn by copying someone and never stop to question if there is a more efficient or easier way to do something. This activity is about the tricky task of pouring from a full container. Could there be an easier way to do it? Read more

Go with the Flow: Model Rivers with Cornmeal, Sand, & Water

Science Fair Project Idea

Scientific Method

Have you ever had fun playing with sand and water, observing how little rivers you create carve their way down to the lowest point of the sandbox, backyard or beach? Some meander, others braid, and some carve a path straight down. Hyrdologists (or scientists who study water) do very much the same thing! Only they set up the model in a particular way, so observing their mini-rivers helps them answer questions about how water flow affects the environment. In this geology science project, you… Read more
