For our physic’s blog post this week, we will share with you what we plan to do for our water bottle rocket project. After looking through websites and finding different ideas for this project, we thought that the most helpful resource site was http://tclauset.org/21_BtlRockets/BTL.html. We liked this website a lot because on top of giving us a summary of how to make our bottle, there was a video to coincide with the instructions given. These videos went step-by-step and didn’t skip any part or make us confused. After watching these videos, we plan to use two soda bottles, create a parabolic nose cone for our rocket, add 3-4 fins (depending, we still have to research what number would be best) and a parachute. We know how to put on a nose cone and attach the correct sized fins according to the video, but we haven’t decided how we’re going to create our parachute just yet. We also decided to create a parabolic shaped nose cone instead of a pointed nose cone because a pointed nose is generally used for objects traveling at the speed of sound. Hopefully what we have planned so far will turn out to be a good start, so we shall see when we begin to put our rocket together :)
I am not to sure if we had to comment on a blog for homework, but that web site is pretty good, I think that our group will consider some of the ideas that it provided.
ReplyDeleteI think that the videos in the link would defintiely be beneficial for those who want a clearer understanding of what to do for this project. I also like the modifications that you both are planning to incorporate and I am defintely curious about how they will work.
