From Black to Clear with the Magic of Photochemistry

Science Fair Project Idea

Scientific Method

The rates of some chemical reactions can actually be increased by adding light. Light sometimes interacts with one or more of the chemicals and provides an "energy boost" that dramatically speeds up a normally slow reaction. In this photochemistry science project, you will experiment with the effect of light on a chemical reaction. The reaction converts iodine, which forms a dark-orange solution, to iodide, which is colorless! Read more

Fruit Juice Distillation

Blog Post

Explore the process of distillation with a kitchen chemistry activity using fruit juice. What role does boiling the juice play in the process? Mixing water (a solvent) and sugar (a solute) together will give you a solution, a homogenous mixture in which the solute has completely dissolved. You can reverse the process and separate the solution back into its parts using distillation. (Note: there are some solutions for which distillation does not work!) In this week's… Read more

Fun or Frustrating?

Science Fair Project Idea

Scientific Method

Is winning correlated with fun? Pick a video game which has different difficulty settings, for example easy versus hard mode. Ask volunteers who have never played the game before to try it out. Some of them should use the easy mode and others should use the hard mode, this will ensure that you have a range in the amount of winning and losing among your volunteers. Keep track of how much each player is winning. Survey the volunteers to find out if they like the game. Do people who win more like… Read more

Gamers: Myth or Man?

Science Fair Project Idea

Scientific Method

Male or female? Fat or skinny? Outgoing or quiet? What is your stereotype of a "gamer"? Do your friends have the same mental picture of gamers? How about your parents? This science fair project will help you examine whether the stereotypes of "gamers" actually matches the reality of who plays video games. Read more

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 Customized Study Flashcards with Artificial Intelligence

Science Fair Project Idea

Engineering Design Process

Have you ever needed to make a lot of flashcards for a class, but didn’t have the time–or weren’t sure how to make ones that actually help you learn? Maybe you like studying on the go, or you’re trying to squeeze in a quick 10-minute review session between other things. In this project, you will learn how to use ChatGPT (or another AI tool of your choice like Gemini, Copilot, etc.) to generate effective study flashcards quickly and customize them to fit your class and… 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
