Today we started designing a roller coaster we looked at some videos to help us get some ideas I looked at this one that Mr Mackie put on the class blog it was about kinetic and potential energy, potential is energy that can create energy and kinetic energy that’s working.
this is my design.
Then we started building our roller coaster I started to get some tube and stick to the chair and make some loops to see what we needed to do I found out that I needed to make Sure to make it have enough momentum to go round the loop. So we started finding to get enough momentum.
I started building again and I started using some different materials and here is some pictures
We tried to put the loop at the end but that didn’t work.
This time we started trying to get long to have the momentum
Here is a video of what we have done
Today we had to do a detailed design showing how our roller coaster works here a picture of mine.
Then started building support
Today we were trying to get the support to hold up the tubing but we couldn’t get it to work so had to build another piece of support to help it. We put a funnel in it to see if that would work.
Today we managed to find a way to hold the loop in the knex support.
we wanted it to have a jump so it would have momentum about it didn’t have enough kinetic energy. We need to find a spot for our loop.
We have changed our design so it has a good speed to get up the loop.
We made so it had enough centripetal force.
These are the important components that keep it together.
This holds up the first bit of tubing and also holds the some of the second piece.
This is the other important part of it because it holds the loop and the tubing that makes the jump into the funnel into the funnel and we have marked where it needs to be so it goes in every time.
Today we had to join our roller coaster onto another roller coaster, the group we joined has a box with a tube going through it and the loop is at the end then there is a connection area then it goes down into ours.
this is the whole roller coaster.
this is the roller coaster we joined.
We had to try and make them join so we
put a knex support tower and a put some tubing and a pencil to hold it together.
Here is a video of what it looks like.
We had to measure the distance between the tubing and funnel it was 47 centimetres.
Today we were told that ours is water slide because it just ends there and doesn’t go back some where, since we knew that ours wouldn’t have enough kinetic energy to make it back we made it turn around go back a bit.
Today we were had to make it more consistent so put a back board on the box were it lands.
Here is an explantry video of our roller coaster
During the session we went around and looked at everyone else’s roller coasters to see what they were like.
her is the finished version of our roller coaster there are our designs and videos and slide shows to show people what design looked like, some were of my part of the roller coaster and some of the part of it.
What I learnt
I learnt a lot of things during this especially about your design compared to your construction and that you don’t much tubing, and you have to pick a good group to join.
I really enjoyed doing the roller coasters because it really challenged us to know what we need and that it is quite hard making your own and then joining it to another groups.
I thought it was good experience because we now what to improve on for next time.
