Egg Drop
My groups ideas were good, we just didn't build our egg drop very well. We had this idea that our parachute would work, but it ended up not being able to hold the weight of the egg, and our popsicle stick thing didn't work as well as we thought it would. If we had built it the right way it might have worked, but we didn't. Our popsicle stick thing was lobsided and the edges were not very high. Then the string that we tied to the popsicle stick thing had one string that was longer than the other which is what made it lopsided, and we didn't figure that out until it was already glued down. Our parachute didn't catch air at all, or else it might have worked a little better.
So if I did it again I would use a trash bag as a parachute because it was strong enough to hold the egg, and it caught air well. Also I would make a box-lik structure like Casey's group did because their's worked really well. I'm not sure if I would have used jello or not because it didn't really seem to serve a useful purpose to me, because I think their's would have worked without jello. Kayla and Maci showed me their's and it had a lot of padding, but it didn't survive the fall in the gym, so that convinced me to go with less padding. One of the other idea's was to have paper around the edges, it worked in the gym, but I can't remember if it worked at the football field. That is what I would do if I could do it all over again!

What I Learned on My Trip
I learned that there are really ghosts, because this man on the boat ride told us this story and at the end we passed this building and the captain's face was on it, I was really freaked out! Also I learned that jellyfish are not made of a clear substance like I thought they would be, they were a blue-purple color. We saw this rocket at NASA and I never thought that the rockets were that huge, it was enormous! On the last day we went to an aquarium and we dissected a squid, and now I know all about squid insides. We also went on a kind of behind the scenes tour and saw all the filters and new and sick animals. That is what I learned on the trip last week!

The Great Depression
I am really glad I wasn't alive when The Great Depression was going on! Some people think that we were really close to a second Great Depression last year! During The Great Depression banks failed and all the money your family had earned was gone, you had to sell your house, etc. More people would have lost their jobs now because one of the reasons so many people were fired during The Great Depression was because machines took over their jobs. Also other businesses had to close down or risk bankruptcy. This is only part of what made The Great Depression so horrible!
