John Evans on 02 Aug 15"As a science teacher, this is the best project I do all year. I have yet to come across a project where students are more engaged. They want to come after school to work on it, they ask to take the project home to work over the weekend, students are shocked when the class period has come to an end, and they all want to skip their next class to continue working. The purpose of this project is to reinforce Newton's Laws of Motion through roller coaster physics. The objective is to have a marble take the GREATEST amount of time to get from the top of the first hill to where the coaster ends. This instructable has also been submitted into the paper contest. I know the competition is fierce so please vote for me!"
