Super Boat Challenge
This lesson challenges learners to design and build a small boat using simple materials, then test its ability to float and carry weight. They will discover the principles of buoyancy and density through hands-on experimentation and critical thinking.
The lesson goal is in this spark, your learner will design and construct a boat capable of floating and carrying weight, explain how boat shape and material distribution affect buoyancy and identify factors that cause objects to float or sink.
