Kick off the school year with this fun, hands-on STEM challenge that gets students working together, thinking critically, and practicing scientific skills from day one! In the Marshmallow Spaghetti Tower Challenge, students work in teams to build the tallest freestanding tower possible using just spaghetti, tape, string, and one marshmallow. The catch? The marshmallow must sit at the very top! This resource is low-prep, high-engagement, and perfect for biology, chemistry, or any STEM class.
