This year was the first year that Mr.Johnson was our teacher she is a really good teacher she is very nice but we don't really do a lot of projects in her class.Out of all the projects we need in her class this year was the roller coaster,We this project when we started to learn about velocity,acceleration,and gravity. 

​

Why I think this is one of my most successful project in this class because we went through a lot of hard  work to build this.It might look easy to build but it is not because you have to find the right height so it can get enough speed to go in the loop. We a different idea put that did  work so we had to come with another idea and that one that work either and that was a lot wasted time so we had to stay after to catch up and not be being on the project
