In this challenge, learners will use what they know about and can investigate buoyancy, forces, and motion to design and build a small-scale engineering buoyant floatation system that will float self-balance, and hold the weight of rocks when they set trail on their waterway path. Just as Indigenous people had to develop solutions for water transportation for migration or trade, students will follow the engineering design process to design and build a buoyant self-balancing system out of cardboard, straws, balloons, and masking tape; floatation designs will be tested to hold weight while self-balancing and buoyant in a water environment.
