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...
