This week is kind of hard to write about since the lowerclassmen had their tests this week. But we did investigate more about how to build our cardboard boats. We also had a lab at the end of the week that allowed us to experiment with surface area and the amount of weight it holds.
I was told this week that if we have a wide surface area on our boats, it will be able to hold and distribute the weight better. But, if it's too wide and there is not enough weight it will sit on top of the water. This will make it hard to steer since there is no water pressure. If it sits to far under the water, then it will be to hard to steer because of all of the waters force on the boat.
This lab that we did on friday was a great example of how the boat takes and distributes weight. If you had a large surface area and a strong bottom, then it would stay afloat. You had to make sure that all of the seams were sealed because water leaking in was the boats downfall.
I believe that I have an idea of what I want our boat to look like. I know that it should have a flat bottom to hold our weight. It should also sink just far enough into the water to give us enough pressure to steer.
