This hands-on Jelly Tower Challenge introduces young learners (K-2) to fundamental engineering principles such as stability, balance, and structure. Using jelly cubes and toothpicks, students will design, build, and test their own towers while exploring the effects of shape and weight distribution. The lesson integrates STEM concepts, including science (stability and forces), engineering (design and construction), and mathematics (measurement and geometry). Additionally, technology is incorporated through videos and AR models of real-world skyscrapers to enhance understanding. A fun twist with light exploration allows learners to investigate translucency, shadows, and light filtering, making this an engaging STEAM experience that fosters creativity, problem-solving, and teamwork.
