Distracted Driver: Do Distractions Affect Driving Video Game Scores?

Science Fair Project Idea

Scientific Method

Have you ever tried rubbing your stomach and patting your head at the same time? What about doing your homework or studying for your math test while watching television? It is tough to focus on a task when you are distracted doing something else, isn't it? In this science fair project, you will investigate how distractions affect your focus on a task, such as driving, by looking at how gaming scores are affected as you're talking on a cell phone or having a conversation with a friend.

Tricks for Treats: How Long Does It Take to Train Your Pet?

Science Fair Project Idea

Scientific Method

Have you ever been to an animal show and seen a sea lion balance a ball on his nose, or a tiger jump through a hoop? Or maybe you've met dogs who can sit, fetch, shake, or beg on command. The range of tricks that you can teach animals is amazing, but how does animal training work, and how long does it take? Find out in this trick-and-treat filled science fair project! Read more

Spinning Colors: How Do Primary Colors Combine to Make New Colors?

Science Fair Project Idea

Scientific Method

Did you know that sunlight can actually be separated into the colors of the rainbow? And the light of different colors can be added together to make white light or new colors. This is an area of study where art and science overlap. In this science fair project, you will explore this area by drawing or painting "pie slices" onto a white circle and then combining them to make a new color by spinning the wheel using an electric drill.

Veggie Snap! Modifying Bending Stresses in a Flexible Rod

Science Fair Project Idea

Scientific Method

Have you ever broken a fishing rod? Or seen a treetop bend over and touch the ground (or even snap off) during an ice storm? These are examples of the effect of bending stresses on flexible rods. There are scientists who actually study this phenomenon and discover ways to prevent breakage, which leads to stronger fishing rods, building materials, car parts, and more. In this science project, you'll explore the bending stresses in flexible rods by testing asparagus stalks. Read more

Macro for Micro?

Science Fair Project Idea

Scientific Method

If the prefix "macro" means large and "micro" means small, then why will the macro setting of a digital camera help take a better picture of a small object? Do this experiment and get the big picture. Read more

Understand Shock Levels and Packaging Principles

Science Fair Project Idea

Scientific Method

When you open up your presents on your birthday, you probably don't spend a lot of time admiring the wrapping—you'd much rather see what's inside. It can be the same way with the packaging that products come in, but packaging is important for protecting the things we buy as they make their way from the factory to our homes. How much shock force is produced when a box gets dropped accidentally? What kinds of materials work best to protect products from damage? This project can show you… Read more

Are Laminates Stronger?

Science Fair Project Idea

Scientific Method

If you love to hit the half pipe with your snowboard or skateboard, then you have tested the strength and durability of laminates. Laminates are sandwiches of different materials that are glued together in layers to give strength and flexibility to an object. In this experiment, you can test if laminating wood can make it stronger and able to support a heavier load. How much weight can it take before it breaks? 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

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

Burning Biofuels: Comparing Nonrenewable and Renewable Fuels

Science Fair Project Idea

Scientific Method

Have you considered where the gasoline that your parents put in your car comes from and how long that source will last? The fuel that most vehicles use, gasoline, is a petroleum product. Petroleum is a fossil fuel and is a nonrenewable form of energy, meaning we use it faster than it is able to be reproduced. Burning fossil fuels also produces pollutants that might hurt our environment. Using a kind of fuel from a renewable source would help save Earth's natural resources and cut down on… Read more
