Today in class we had our test which I honestly think i did terrible on. It had to do with all the unit 8 things we have learned for the past couple of days. Today was spent mostly on our rockets though, we're building rockets that are supposed to stay in the air for at least ten seconds. We're competing against the other class and hopefully we'll win! My groups rocket consist of three bottles taped together and we'll use 1/2 a liter of water then pump it to about 67psi. So far our rocket has only stayed in the air for a max of 5 seconds but reached a height of at least 50 feet. This rocket isn't one of the best but i'm sure that once we add a parachute it'll be able to last more than 10 seconds. the way our parachute will work is it will be packed inside the nose cone. once the nose cone falls off the parachute will open up and everything will be OK! That is if everything goes according to plan, unlike the egg drop failure. I hope that this rocket does great tomorrow because we have all day to make changes. Chee go team Blake!
Our super nuts rocket :D hopefully this thing can get more than 10 seconds in the air. The coke bottle is the top and the Mountain Dew bottle is where the fuel (water) is stored aka the bottom.

Thats ok, I didn't do great on the test either. Anyway, I think your rocket will do very well because it is so long. I read that the longer the rocket, the more stable it is, so it will probably stay in the air longer. Good luck!
ReplyDeleteYeeaaaa good job explanation of our endeavors. I think that if we improve today we can have a 10 second rocket!
ReplyDeleteI like how you explained the physics and we will most definitely get a ten second rocket.
