Have you ever seen pictures or videos of a roof being blown off a house during a hurricane or tornado? You might be surprised to hear that the roof is actually not pushed off by the strong winds but instead by the air inside the house! This can be explained by Bernoulli's principle, which states that fast-moving fluids or air, such as strong winds, have lower pressure than slow-moving air. In this activity you will demonstrate how balloons can be moved in a similar way. It is not quite as… Read more

K-ESS2-1. Use and share observations of local weather conditions to describe patterns over time.

Bombs Away! A Ping Pong Catapult

Science Fair Project Idea

Scientific Method

If you were in a raiding army in the Middle Ages, a catapult would come in mighty handy for taking down castle walls. But only if you could aim it reliably! With this science project, you will try your hand at catapult technology. Using a rubber-band-powered catapult you will send ping pong balls flying through the air. The catapult's design makes it easy to measure and repeat how hard the ball is launched and its direction, so you can find the right catapult settings to hit the target reliably. Read more

How does a cooler keep things cold? Which material makes the best insulation? Try this project to find out how long you can keep an ice cube from melting once it's out of the freezer! Read more

Build a Levitating Water Fountain with the Stroboscopic Effect

Science Fair Project Idea

Engineering Design Process

Can you make water fall up? Or make drops of water hover in mid-air? While you might not be able to make water defy gravity, you can create the illusion that it does using something called the stroboscopic effect. In this project you will make use of the stroboscopic effect to build your own "levitating water" fountain. Read more

Building the Tallest Tower

Science Fair Project Idea

Scientific Method

Skyscrapers are impressive structures. What does it take to design a building so tall? Engineers use strong materials and innovative design to push the limits of gravity. They use special tables to simulate earthquakes and test models of their buildings. In this project, you will build your own earthquake table and see how tall you can make a tower out of LEGO® bricks. You can even measure how hard your earthquake table shakes using the accelerometer of your smartphone and a sensor app. Read more

Can You Train People to Breathe Better?

Science Fair Project Idea

Scientific Method

The practice of "belly breathing" has been linked to improve mood, relaxation, and even have physical benefits like lowering your heart rate when compared to chest breathing. However, most of the time, we do not think about breathing—our bodies do it automatically. How do you know if you are belly breathing instead of chest breathing? How can you practice and get better at it? In this project you will build your own device to provide visual feedback about how a person breathes, then see… Read more

Cosmetic Science: Testing Lip Balm Recipes

Science Fair Project Idea

Scientific Method

Did you know that cosmetics companies employ teams of specialized scientists to develop and test each new line of makeup, perfume, lotion, or soap? This science project lets you be the cosmetics scientist. You will create your own lip balm right in your kitchen using a short list of ingredients, then test it, and follow up with some creative cosmetics science of your own! Read more

Craters and Meteorites

Science Fair Project Idea

Scientific Method

Have you ever heard someone say that the moon is made of cheese? Even though the craters on the surface of the moon resemble holes in Swiss cheese, we know that this common myth is not true. Find out how craters are formed and why they are different sizes by doing this simple science project. Read more

Design a Mini Solar Tracker System

Science Fair Project Idea

Engineering Design Process

How can you squeeze as much power as possible out of solar panels if you do not have a lot of space to install them? By tracking the sun! Keeping a solar panel pointed directly at the sun throughout the day can maximize the amount of power it produces. In this project you will design, build, and test your own miniature solar tracking system using a fun block-based programming language - no coding experience required! Read more
