Structuring 

Our original idea was very vauge. we didn't have a great concept of what we wanted to do and kinda just sketched down some ideas and picked the one we liked best. It had a very simple yet complicated design to make with limited time we had, and being new to physics we struggled at first with the first concept. 

The final blueprint was thought out better than the first. maybe not as unique and complicated as others were but much better than the first blueprints none the less. We took out the spiral and replaced it with a half pipe and a tube for the ball to go through. The pulley system was structured better and the end step was completely taken out. The first lever idea was replaced with a simpler one. As well as the second ramp being replaced with a stair ramp. We learned from our structural mistakes throughout the course of our project and finished with something we were proud to present.
