Hey peoples,
For inquiry we are looking at rockets and space. We have engineers come in on Tuesday afternoons who teach us about rockets. But, if rockets go up with energy they must come down, and a safe way is air!
On Thursday and today (Monday), we were given the task to construct a parachute. Our goal was to try and make it go as slow as possible. We also had to attach 2 hex nuts to the parachute. We were to do this in groups of three, I did it with Zara and Pippa.
Here is a photo of our initial and final diagram:
For the initial design we used fabric and string we thought this would work well because the fabric was light. When we first tested it by standing on the chair it went fairly well. But when we took it upstairs to test it it spun in circles rather fast.
The final design we thought we needed something that would block the air out so it went rather slow. We decided to use thick paper. When we got it tested it took 1.83secs to get to the bottom. We decided to add an extra layer of paper that had space for air to make it billow out. This made it go slower (2.00secs), we were quite pleased with the result.
In the future to improve I think we need to think about how we can add more materials to make it go slower but not add too many materials so it is too heavy.
Here is a photo:
Hope you learnt something!
See ya later!
