9th Grade Boat Project:
For this boat project mot many materials were needed and it wasn't as hard to make as it looked. The two most important materials were cardboard to make the a boat and tape to put the boat together and prevent water form coming into the boat. We also used box cutters to make it easier and to cut the cardboard neater. We were also allow to tape bottles to our boat to make it float and not sink as fast.

Reflection:
How would you change your desing now after testing your full scale mode?
I change the design of my boat very little; I actually liked the
first design we did so we decided to keep it. One of the few things we changed
to the design was to put more cardboard to the bottom of the boat. This was
because it made it hard for the water to go in the boat since it was going to
have to go through two pieces of cardboard. Another change was to wrap the whole
boat in tape especially the outside of the boat. This would help it be more re
enforce once it hits the water. The last thing was to not have the sits taped to
the boat. We did this because when we enter the boat we were going to have to
move around in order to balance the boat.
Describe three things that you saw other students do that you consider to be very affective?
Something that I saw other student’s do that was very effective was that
they tried not to move around that much inside of the boat. This technique was
very helpful because it kept their boats balance and not moving to much so water
would not go into the boat as quickly as it was going into the other boats. I
also saw that peoples boat was thin and not to tall. This made it easy for them
to go faster in the water.
Why did your boat float?
Objects float due to the buoyant force acting up on them once they are placed on a fluid. If the buoyant force is greater than the weight of the object the object will float, but if the
weight of the object is greater than the buoyant force acting on the object the
object will sink. That is why my group had to find how much our boat weight in
cubic feet. For every cubic of water that our boat displaced there was a buoyant
force of 62.4ft3 acting on our boat. In this case our boat could hold more that
the weight of the people going in it. This proved that our boat was going to
float once it got on the water.

My Effort Reflection:
Over all I put on a lot of effort on this project such as my partners Ashley and Varinia. I made the design for our boat and figuered out in what ways we could fold the carboard in order to reinforce the sides and bottom of our boat. I also made all the calculation of the boat to see how much it weighted and also find out the buoyancy of our boat.
