Abstract Forget drinking your juice. Instead, try snacking on it! Use the steps and recipes in this food science project to transform drinks into semi-solid balls that pop in your mouth. The technique is called spherification and it is part of a larger food science trend called molecular gastronomy— but we just call it yummy science!   Recommended Project Supplies Get the right supplies — selected and tested to work with this project.

Abstract Does growing your own house sound futuristic? If so, this project might surprise you! An overlap of biology, material science, and environmental science has resulted in some intriguing self-assembling materials. In this project, you will grow one of these materials: mycelium composite. It is made of agricultural waste and mushroom roots. You will explore two ways to grow your own construction material. Try it out and see which method proves...

Abstract Do you think artificial intelligence (AI) is too complex to use? Think again! In this project, you will use AI to teach a web-based tool to classify happy and sad faces, or other objects, poses, or sounds. This experiment requires no coding skills; instead, you will need curiosity, creativity, and a critical eye. Why not give it a try yourself? Objective Use a Teachable Machine to teach a web-based tool to classify...

The body's key balancing and equilibrium center lies within the ear and is known as the vestibular system. It is a collection of inner ear structures close to—but independent from—those that amplify and transmit sounds to the brain. Rather than sound, the inner ear's vestibular system conveys information about motion and position. This system tells us, even when our eyes are closed, if we are standing tall or balancing on our...
