MrBeast, the world's most famous YouTuber, has a series of challenge videos where he asks a contestant to protect some valuable prize - like a pile of money or an expensive car - from a series of attacks like explosions, giant fireballs launched from catapults, or even getting hit by a train! Contestants often have only 24 hours to build something to protect their prize, which presents a very interesting engineering challenge. Given limited time and access to materials, how can you best protect…

Solar cells are an alternative method for generating electricity directly from sunlight. With this project, you can get down to the atomic level and learn about the world of solid-state electronics as you investigate how solar cells work. Your experiment will measure the effect of changing light intensity on power output from the solar cell. A possible variation would be to investigate the effect of changing the color of the light.

Many materials expand when heated and contract when cooled. What do you think will happen to the elasticity (stretchiness) of a rubber band when it is heated or cooled to various temperatures?

Don't you just love listening to music? In the 1980s, people listened to music on the Sony® Walkman®. Now, people listen to their favorite tunes on MP3 players and on their Apple® iPhonesTM. But listening to music on devices actually started in the late 1800s and early 1900s. In those days, people would gather around their phonograph to listen to their favorite tunes—people were just as amazed with the phonograph as you would be to handle an iPhone. In this physics science…

Nut clusters, chocolate-dipped candies, and chocolate-dipped strawberries are just some of the delicious goodies that have a thin, rich layer of chocolate wrapped around them. But how do pastry and candy chefs make these delectable treats? The first step is to melt and temper chocolate. Tempering is a process in which the cocoa butter in chocolate is hardened into a specific crystalline pattern. When the cocoa butter molecules are in this pattern, the chocolate is shiny and breaks with a sharp…

Have you ever seen clothing with built-in lights? This might sound like something out of a science-fiction movie, but electronic textiles (>e-textiles for short, also called wearable electronics or sewable circuits) really exist. Instead of using hard surfaces for circuits (like what goes inside your computer or cell phone), e-textiles weave electrical parts like batteries, wires, and lights directly into clothing that you can wear to make the clothing do fun, interesting things like light…

Have you ever looked up at a skyscraper and thought "That is so cool!"? Building a skyscraper, or any structure, is more than just building the walls, windows, and floors. All structures require a foundation to keep them from falling down. This is especially important when a structure is built on a hill or on a slope. In this science project, you will build a tower of Lego® Duplos® on slopes with different angles. You will investigate how deep you have to dig the foundation for each…

With heat waves impacting the world globally, many gardeners, farmers, and scientists are turning to passive irrigation systems that reduce fossil fuel emissions while keeping plants well-watered and alive in the sweltering heat. In this science experiment, you will compare and contrast the effectiveness of passive irrigation systems compared to traditional surface irrigation systems and their impact on overall plant growth.

The "impossible arrow" is an amazing optical illusion: an arrow that always seems to point to the right, even when you rotate it 180°. If you place the arrow in front of a mirror, however, its reflection points to the left! How does this illusion work? Can you design your own "impossible" shapes? Try this project and find out!

Has your house ever suffered an ant invasion? This project is an interesting way to investigate what substances are effective as ant repellents. The goal is to find substances that keep ants away, yet are safe for humans and the environment.
