I Put 45 Points!!Use what you have learned from this chapter to make a model boat out of a 10-cm square piece of foil. Test your model boat in a tank of water to see how many pennies it can support before sinking. Compare the performance of your boat with those of your classmates. Suggest several design improvements based on your results. Respond to at least one other students posting giving suggestions on how the model of their boat or yours could be improved to increase buoyancy.

So basically they are asking you to make a model boat out of a 10-cm square piece of foil, according to what it says in the book you have read.


Then just follow the instructions they give to you, like so: 

1. Test your model boat in a tank of water to see how many pennies it can support before sinking.

Then, after you do that (theres no need to record a video or take a picture thats up to you) all you have to do is: 

Talk about how the model of your boat could be improved, or made better to one of your classmates (but post it on the discussion board)
