During the Mars 2020 mission, NASA plans to explore the surface of Mars using a rover in combination with a lightweight helicopter. To be able to fly on Mars, this helicopter must be super light and have very efficient blades. If not, it will never generate enough lift to get off the ground. In this activity, you will make your own paper helicopter and test different blade designs. Will your findings be reflected in NASA's design? Try it out and see for yourself! Read more

It’s fall, which means flu season. We all know that washing hands a few extra times a day can help keep colds and flu at bay, so we wash hands frequently and use a paper towel…then another one, maybe even three or four to dry them off. Because who likes to go out with wet hands in cold fall weather, right? But could there be a way to conserve some of that paper, and get a paper towel to go the extra mile, allowing you to dry your hands with just one single sheet? This… Read more

Frequency-Dependent Sound Absorption

Science Fair Project Idea

Scientific Method

Want to start a garage band, but Mom or Dad won't let you because it will make too much noise? This is a good project for someone who is interested in acoustics and likes to build things. Who knows, it might help you figure out how to make everyone happy. Read more

Guitar Fundamentals: Wavelength, Frequency, & Speed

Science Fair Project Idea

Scientific Method

This is a rockin' project for guitarists with an interest in the physics behind the music. Have you ever wondered why the pitch of the note changes when you fret the string? You can find out for yourself with this project on the fundamental physics of stringed instruments. Read more

Here Today, Gone Tomorrow: Saving Migratory Animals

Science Fair Project Idea

Scientific Method

Extinct might be a word you associate with animals that lived long ago, like the dinosaurs, but did you know that over 18,000 species are classified as "threatened" (susceptible to extinction) today? Scientists involved in wildlife conservation have a tough job; they are in charge of determining what needs to be done to prevent a species from becoming extinct. Habitat, food supply, and impacts of local human populations are just a few of the factors these scientists take into account. It is a… Read more

How Antacids Relieve Heartburn

Science Fair Project Idea

Scientific Method

Have you ever experienced heartburn after eating a large, greasy meal? Or have you heard of someone complaining about heartburn pains? It's very common; over 60 million people in the U.S. have heartburn at least once every month. Heartburn pain usually results from stomach acids escaping from the stomach and irritating the esophagus above it. Luckily, there are medical drugs, called antacids, which can help relieve heartburn pain. But how do antacids work, and how effective are they? In this… Read more

How Do Roots Grow When the Direction of Gravity Changes?

Science Fair Project Idea

Scientific Method

You might not know it, but plants are able to sense their environment and actually respond appropriately. One of the key parameters that every plant must respond to is the direction of gravity: stems go up (opposite to the pull of gravity) and roots go down (in the same direction as the force of gravity). In this project, you will construct simple devices that hold several germinating seeds, which allow you to watch how growing rootlets respond as you rotate the devices, effectively altering… Read more

How to Extract Energy from Grass

Science Fair Project Idea

Scientific Method

Mowing the lawn is hard work, especially on a warm day. Not only do you have to mow the grass, but you also have to dispose of the clippings. Some people add the clippings to a compost pile in their yard, which is a great idea. But did you know that some grasses can be used as a source of energy? In this energy science fair project, you will learn more about a type of energy called biomass energy. You will grow different kinds of grasses and see which type of grass gives you the most biomass,… Read more

How well do you wash your hands? Do you just give them a quick rinse with water, or do you use soap? Do you wash the backs of your hands and in between your fingers? Good hand washing is one of the best ways to prevent the spread of germs and diseases like the flu and common cold. Try this activity to find out if there are hard-to-wash parts of your hands where germs might be hiding! Read more

Huddle & Cuddle: How Puppies Keep Warm

Science Fair Project Idea

Scientific Method

What is the first thing you do when you wake up on a cold, frosty morning? Snuggle down deeper under the covers? Animals, like puppies and piglets, do not like being cold either, but they do not have hands or blankets to wrap themselves up. So when animals get chilled, they change their behavior and do things like huddle—they curl up close to other animals. In this mammalian biology science fair project, you will see just how much huddling can help reduce heat loss. Read more
