Did you know that airplanes and sound have something in common? Can you guess what it might be? Air pressure! It is fascinating how air—something that is so fluid and invisible—can power an amazing number of fascinating phenomena. In this activity you will use your own breath to blow a small paper ball into an empty bottle. It sounds simple, but is it? Try it out and see for yourself! Read more

How Many Cranks Does It Take to Power a Hand-Cranked Radio?

Science Fair Project Idea

Scientific Method

If you lose power, you can probably still access the internet and read the news with a cell phone. But what if the power goes out for so long that your phone battery dies, or if cellular service also goes down? How would you get news from the outside world? In emergencies, you can use a hand-crank radio, which is powered by manually turning a crank. But just how much power do you get when you turn the crank? How long will the radio stay on before you need to charge it again? Try this project to… Read more

How Much Weight Can Your Sandcastle Hold?

Science Fair Project Idea

Scientific Method

Do you think a sandcastle can support a brick? How can you change a sandcastle to make it support more weight? Find out in this fun science project! 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

How Shoe Tread Affects Traction

Science Fair Project Idea

Scientific Method

Have you ever noticed that some shoes grip the ground better than others? The pattern and design of a shoe’s tread can affect how slippery it is on different surfaces. You can test shoes with different tread patterns—like flat, ridged, or patterned—to see which design provides the best grip. By dragging a shoe along a surface with a spring scale at a constant velocity, you can measure how much force is needed for each shoe to slide on various surfaces. With this knowledge, you… Read more

Have you ever wondered how strong hair is? When we talk about our hair we usually discuss color, length or texture. But what about hair strength? If you look at a strand of hair, it looks like a very thin string. In fact, it is on average only about 0.1 millimeters thick. It doesn't seem like such a thin string could withstand much force. How much weight do you think a single strand of hair can carry? In this activity you will put a hair to the test and find out. You might be surprised by your… Read more

Human-Robot Interaction: Do Looks Matter?

Science Fair Project Idea

Scientific Method

Do you think robots are cute? Funny? Scary? How do robots make you feel? What words would you choose to describe a robot? Find out how people react to robots by building and decorating your own robot in this science project. Read more

When discussing material properties, most of us usually think of solid materials and material properties such as hardness, flexibility, or strength. However, liquids are characterized by distinct properties, too. Some of these properties overlap with those of solids, like density or transparency, but others are more specific to liquids. Viscosity—the resistance of a fluid to flow—and surface tension, are two examples of properties that are specifically used to characterize liquids.… Read more
