Why Winglets?

Science Fair Project Idea

Scientific Method

Have you ever noticed how some jet planes have small, vertical projections as the tips of the wings? They're called winglets. What are they there for? Read more

Experiment with Making Gels

Science Fair Project Idea

Scientific Method

Chances are, you have several materials around your house made of gelatinized materials. Gels are used in all kinds of products and materials: pudding, diapers, insoles, packaging, ice cream, toothpaste, and many more. In this project, find out how gels are made and how they can be adjusted from firm to soft by changing the ingredients. Read more

Learning Your A, G, C's (and T, too)

Science Fair Project Idea

Scientific Method

This is a project about the "molecular alphabet" of DNA. With just four "letters," it manages to keep track of the plan for an entire person, and keep a complete copy in nearly every cell. This project will help you start learning this new alphabet. Read more

How Much Worm Is a Worm?

Science Fair Project Idea

Scientific Method

Worms are slimy, wiggly, and gross. But did you know that they have many unique abilities? One of the neatest things that worms can do is regenerate, or re-grow, parts of their body. After a piece of a worm is cut off, it can grow back with all of the necessary new parts. How much of a worm can you cut off and still get regeneration? Is one end of the worm better at regenerating than the other? See if you can make heads or tails of this wiggly problem! Read more

Throwing You Some Curves: Is Red or Blue Longer?

Science Fair Project Idea

Scientific Method

This a straightforward, but interesting, project in geometry. It is a good first proof to try on your own. You should be able to figure it out by yourself, and you'll gain insight into a basic property of circles. Figure 1 below shows a semicircle (AE, in red) with a series of smaller semicircles (AB, BC, CD, DE, in blue) constructed inside it. As you can see, the sum of the diameters of the four smaller semicircles is equal to the diameter of the large semicircle. The area of the larger… Read more

Ring of Fire 1: What Volcanoes Tell Us About Plate Tectonics

Science Fair Project Idea

Scientific Method

The Ring of Fire is a region of volcanic and earthquake activity that surrounds the Pacific Ocean. In this project you can explore the connection between plate tectonics and volcanic activity by mapping historical data. Read more

Is That Cat Overweight?

Science Fair Project Idea

Scientific Method

Did you know that there are millions of overweight cats and dogs in the United States? Is your pet one of them? How about your neighbor's cat or your grandma's dog? In this science project you'll determine what percentage of the pets you know are overweight and how their weights compare to pets' weights throughout the United States. Read more

Slip Sliding Away: Experimenting with Friction

Science Fair Project Idea

Scientific Method

As you headed up the mountain to enjoy your last ski trip, you may have noticed a sign reading: Hazard! Icy Roads Ahead—Put On Your Chains. Putting chains on car tires increases the resistance between the tires and the road allowing the car to "grip" the road. This resistance to sliding is called friction. In this experiment, you will be investigating how to increase and decrease the friction between two surfaces. Read more

Where Did All the Stars Go?

Science Fair Project Idea

Scientific Method

One of my favorite things to do when I was a kid was to go outside and look at the stars. As an adult, I moved to a major city and the stars seemed to vanish from the sky. Where did they go? Read more

Do You Have the Willpower to Taste Something Sour?

Science Fair Project Idea

Scientific Method

If you developed a super-sour candy, drink, or dessert, to whom would you sell it? Do people of all ages love sour, or is there a difference between the sour preferences of kids and adults? In this mouth-puckering science project, you will find out by making batches of lemonade that vary in their sourness and have volunteers taste them! Read more
