The assignment is to build a boat.

The boat has to float if I up weights on it. It has to float until 499 g and sink at 500g. My boat doesn’t sink at 500g. It sinks at 700. I will be adding counter weights on it.

I use wire to form the shape of a b arch and used aluminum foil to overlap it. There is a report I have to write according to the rubric attached. Please write it according to the rubric. If there is enough time, you can also suggest me what material I should use for counterweight. Write about torque, density and buoyancy too. Please only do it if you have a good understanding in these topics. Thank you.
