Recovery Systems

Yesterday in class, I did a lab called Recovery Systems. My partners for this lab, were Kimmy and Em. In it, we had to make a parachute out of a plastic garbage bag, string, a hole puncher, hole punch reinforcement stickers, scissors, tape, and a hair dryer. Also, we had some balloons that were filled with sand. We started, by tying a sand bag to a big garbage bag, and blowing hot air from the hair dryer into it. That didn't work, because it was too flimsy, and it would fall down and crumple up really quickly. So, we cut the end of it off. Em worked with that, and made a parachute out of that the same way, but Kimmy and I wanted to make a smaller neater parachute, so we decided that Em would make a big one, I would make a small one, and Kimmy would write down what happened. Then, we would have two models (maybe more) and from that, we would decide which one worked better, and was a better model. The bigger one that Em made, fell just as easily as the one we had made original, so we tried out mine. That didn't work either, because it was too small, and the string was uneven, but it did work better. Then, Em came up with the idea of making a second parachute, and attach it to the top of my model, like a bi-plane. I'm not sure if they got a chance to make that version, because the soccer team was called to the front desk for early dismissal to go to the game, and I am on the soccer team.
