The Great 9th Grade Odyssey Project
What was required for this project was to create a boat out of different materials and see how long it could float. For this project we had to calculate different units such as mass, length, volume, etc in order to see if our boats could float. We then created our boats and tested our boats.

Reflection - The Great 9th Grade Odyssey
When we first tested our ⅛ model, it sunk because the water bottles were uneven and it was very unstable. When we created our full scale model we changed a lot of things. We decided to take off the wings on the sides. We also decided to put in chairs so rowers could easily row without having to reach over the sides. Our boat seemed to be very effective. It floated and was very waterproof. Although it had some positive outcomes, there are still some things that I would have changed. For instance, I would have lined up our bottles on the bottom evenly and matching, meaning making each bottle like water or soda bottles match together. In addition, I would also have stuffed our chairs and made them water proof to make them very strong and not become dead weight like it did during the race.
There were a lot of things that I saw very effective that the other teams did. For instance I saw a group who had there bottles lined up evenly and perfectly aligned which gave them good stability. I also saw a group that double layered the tape all around their boat. Last, while in the race I saw a team that was sitting very straight which let them have good stability.
The Archimedes Principle states that ,”The buoyant force on a body immersed in a fluid is equal to the weight of the fluid displaced by the object.” This applies to flotation because when putting force on an object, the stronger the buoyant force must act to let it float. If the weight is too strong, the buoyant force fails and the object sinks. The reason why certain objects float in water is because they have lower densities than water. Water has a density of 1.0 g/cm3 so if anything with a lower density than will float. Our boat floated because our boat had a lower density than water. When we did our calculations for our boat, our density was 0.01 so it was able to float. Average density is the mass divided by volume. When you have so many different materials used for an object this is where average density applies to.

Reflection of Efforts
I think that in this project I put a lot in effort in to it. I helped my group out a lot, contributed, and worked as a team.
