FC: U.S Rocket | By: Kei
1: In Mrs.Sims class everyone in class did a experiment to see which Solvent, Solute, and what size of Alka Selter is right for a rocket. | The name of are group is called U.S.
2: Imagine | In Mrs.Sims class we did many experiments. The first experiment was to chose if you wanted cold water, room temperature water,or hot water. We had the same amount of water,a timer and the same amount of Alka Seltzer. Hot water dissolve the Alka Seltzer the fastest.
3: Imagine | Then are second experiment was which solvent is the best to use for the rocket. The choices was water,vinegar,or oil. We will use water for the solvent because it dissolve the Alka Seltzer the fastest.
4: Are last experiment was to see how much Alka Seltzer we should put in the solvent. It was either crushed Alka Seltzer (Powder like) or whole Alka Seltzer. We choice whole Alka Selzter because it dissolve the slower. | Imagine | The reason why we choice the slower one because we need time to put the lid on and shake it.
5: On are rocket we wanted to the nose cone (which is the top) to be pointy. The rocket fins would have three of them and it would be a triangular shape. The solvent was hot water and the solute was a whole Alka Seltzer. | Plan
6: Design | When we meet everyone did a part. Alex made the nose cone (the top) Me and Stella both made the the fins (wings) and Dom and Jeffrey both taped it to the rocket. | Then when we finished it didn't fly. We had a hard time putting the lid and when we put it on the ground the water fell down.
7: Improve | On our second idea we did was the rocket would have four fins (wings) which is made of construction paper. It was a triangular shape. We used hot vinegar and a small piece of Alka Seltzer. | This time it fly! Are rocket work!
