What's the Best Way to Guarantee Fresh Bread?

Science Fair Project Idea

Scientific Method

Have you ever bitten into a slice of bread only to find that it no longer seems fresh? Instead, it has the firm, undesirable texture that comes about when the bread is going stale. Chemically, what happens during the staling process? Can it be reversed (at least temporarily)? Do some background research to answer these questions and then apply those answers to one (or more) of the following experiments to find the optimal state to keep your bread fresh. Experiment 1: What Temperature Keeps… Read more

Do Warmer Seas Make Stronger Hurricanes?

Science Fair Project Idea

Scientific Method

We've all heard that hurricanes draw their immense power from warm ocean waters. Of course, many factors contribute to the formation and growth of a hurricane, but can we expect to find that the warmer the water, the stronger the hurricane will be? This project shows you how to use online data archives to investigate this question. Read more

What is the Rate of Leaf Growth Along the Stem?

Science Fair Project Idea

Scientific Method

Leaves grow in a different pattern than stems and shoots. They do not elongate along one axis, but instead spread out over time. Do all regions of the leaf grow equally? You can use markings on different regions of a growing leaf to see if the whole surface grows, or if growth is focused in a particular region, like the veins or edges of the leaf. If you look along a leafy stem, you may notice that leaves at different positions along the stem are different sizes. You can do an experiment to… Read more

Make a Hygrometer with Strands of Hair

Science Fair Project Idea

Scientific Method

Does your hair go crazy when the weather turns damp? Did you know that strands of hair can relax and lengthen when the humidity increases and then contract again when the humidity decreases? In fact, hair strands can be used as the basis for a hygrometer, a device which measures the humidity level in the air. Will a hygrometer help you to predict bad hair days(!) or can you use it to help predict the weather? Read more

Pick This Project!

Science Fair Project Idea

Scientific Method

Here's a fun science project for anyone who plays an electric guitar. You'll learn about the physics of vibrating strings, and find out why the tone of your guitar changes when you switch between the different pickups. Read more

Paw Preference in Pets

Science Fair Project Idea

Scientific Method

The great majority of people have a distinct hand preference. How about animals like dogs or cats? Do they show a paw preference? If you like animals, this science fair project might be for you. Read more

Designing an AI Agent for Expense Tracking

Science Fair Project Idea

Engineering Design Process

Do you have a hard time keeping track of how much money you spend? What if you could automate the task somehow? In this project, you will explore how to use ChatGPT’s Agent mode to create an expense tracker spreadsheet. Read more

Hit Boxes: How Size Affects Score

Science Fair Project Idea

Engineering Design Process

Video games come in many varieties: aim-and-shoot games, city-building games, racing games... the list goes on. In many, you get points for colliding with or hitting something. In this computer and video games project, you will learn about how hit boxes are used to detect collisions and you will determine if the size and placement of a hit box affects the score in the game.

Measuring the Surface Tension of Water

Science Fair Project Idea

Scientific Method

Did you know that when you dip your finger in water and pull it out, the water is actually pulling back on you? Here's a way you can measure how much. Read more

The Brains Behind 'Where's Waldo?'

Science Fair Project Idea

Scientific Method

What makes you notice someone in a crowd? Why do some things stand out, while others melt into the background? In this science project you can investigate the psychology of how things get noticed, by studying how our brains perform a visual search. Have you ever looked and looked desperately for something? It is so frustrating! The classic example is when I lose my keys. You would think that by now (knowing that I am the kind of person who often loses my keys) I would have a huge, bright red… Read more
