Have you ever looked at pictures of murals on buildings from hundreds of years ago and wondered how they were created? Fresco is a type of painting that has been used for thousands of years and involves painting on wet lime plaster. This activity explores one aspect of the science behind this unusual technique. See how science can help you become a more versatile artist! Read more

The Touch Response

Science Fair Project Idea

Scientific Method

All animals need to respond to changes in their immediate environment. The sensory structures of animals are each made to respond to distinct types of sensory stimuli: touch, taste, sound, light and smell. How are these stimuli received? Different animals have different strategies for receiving stimuli and develop specialized structures for doing so. Antennae, ears, noses, tongues, eyes, eye spots, hairs and bristles are all examples of sensory structures used by different animals to sense… Read more

Have you ever wondered what keeps you in your seat when you are riding a giant loop-de-loop roller coaster? Surprisingly, it is not the seat belt! You are kept in your seat because of something called centripetal force. Centripetal force actually does much more than make a ride on a roller coaster's loop possible — it keeps a satellite in orbit and you in your bicycle when taking a tight curve! In this science activity, you will use marbles and Jell-O® to investigate centripetal… Read more

There's a Machine in My Toy Box!

Science Fair Project Idea

Scientific Method

"What?! Many of my toys are also machines?" That's right—simple machines! Simple machines are everywhere! Under your feet when you climb stairs, in your hand when you use a utensil to eat your dinner, even in your arm when you throw a ball. Come visit this science fair project and explore the six types of simple machines. Find out how many are hiding under the hinged lid (yes, another simple machine) of your toy box! 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

Time is Money

Science Fair Project Idea

Scientific Method

How many times have you heard from your parents: "Clean up your room!" or "Don't forget to unload the dishwasher!" By applying principles of industrial engineering and time management, you can speed through your chores and have more time to kick back and relax. Read more

Top Crops: Finding Hidden Grasses and Beans in Processed Foods

Science Fair Project Idea

Scientific Method

It's the bottom of the ninth, and you've spent a great afternoon at the ball game with a hotdog, a soda, and an ice cream in hand, but I'll bet you're not thinking about how many crops went into those classic baseball snacks. Sure, the bun contains wheat, but did you know that the hotdog might contain wheat, too? And soybeans may have been used to give that ice cream its perfectly smooth texture, while corn was likely used to sweeten the entire meal! Crops can be changed and added to processed… Read more

Turning Mushrooms into Environmentally Friendly Packaging

Science Fair Project Idea

Scientific Method

Have you ever questioned the packaging of an item in a plastic container, secured in a plastic mold, that also slides into a plastic box, or a small item packed in twenty times its volume of polystyrene noodles to keep it from breaking? In this project, you will explore if mycelium composite material, an eco-friendly material obtained from organic waste and mushroom roots, can serve as a viable eco-friendly packaging alternative. Packaging material made of foams and plastics (Figures 1 and 2)… 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
