Day 1: finished brainstorming designs for boat. We all discussed what we thought the timeline should look like and then we each came up with an idea for a prototype. We all thought of idea 1, idea 2 was Davina's, idea 3 was Hannah's, and Idea 4 was Meera's. We came to a conclusion that 2 was the best because it was very practical and not to complex.
Day 2: Finished calculations and started drawing real dimensions to determine how large the boat would be and how much it could hold. As a group we figured out how to find the density of the pool water and then used that and the mass (once we weighed ourselfs) to find the volume displaced. Davina then found the depth that it would be underwater and Meera used trigonometry to get the dimensions of the sides and triangles of the boat as well as how much the boat could carry.
Day 3: Finished photo of prototype and ready to build real prototype. Hannah measured the diminsions for the prototype to be 1/10th of what the boat would actually be. Then we started to cut out pieces for the protype of the boat.
Day 3: prototype design finished! To do this, we needed to make sure the dimensions of the boat would be able to fit together. we designed the protype with the blue paper and then used the purple paper to show where we would double layer the inside of the boat with extra carboard.
Day 3: We next used the prototype to figure out the dimensions we would need for the real boat. Using a meter stick we started measuring cardboard for the boat and began to cut out boat pieces. Davina cut the sides of the boat, Meera cut out the front triangles, and Hannah cut out the base.
Day 4: Once we had all of the pieces cut out to the correct measurements, we started thinking about assembling the boat. We got our first role of tape and started by taping one section at a time. Davina and Hannah taped the front of the boat first, while Meera started to connect and assemble the base and sides.
Day 5: last day building the boat. We worked toegther to double layer tape where it needed to be and we secured the sides to make sure no water could get through. Meera and Hannah worked on taping while Davina was designing the outside of the boat!
Day 5: final boat is finally done. We checked to make sure Davina and Meera would be able to fit correctly in the boat while also making sure we knew how to row! We added final touches to the boats design and structure and decided that it was done!
Reflection: During the boat project we were very apprehensive of our measurements and design. We drew many different prototypes and had lots of ideas for what the boat could look like but in the end we went with the one that looked the most reliable. We were worried that it would be difficult to build our actual design but we decided that we should try and see what would happen. It was also difficult to get the correct measurements, but once we did it was much easier than what we thought it would be. That showed that we knew how to do the math, and it was just the conceptual part of learning that we had to get better at. After we got the math and built the prototype, we had to make sure we would have enough cardboard and it would work well with our design. While building the boat, the obstacles we faced were being able to measure the cardboard correctly and having enough duct tape. We did run out of duct tape by the end but we had to hope that our design was strong enough for the boat to do well.
