Grade 4 students were tasked with constructing a submarine. It needed to sink slowly and gracefully underwater. Only recycled materials were permitted in the making of this. The cargo, like the boat, was 30 marbles. One could see that our students asked good questions, had thoughtful ideas on how to tackle the sinking problem and were thinking like scientists. Many discussions generated inventive and ambitious ideas.
