The Challenge
Imagine you are taking on an exciting challenge: designing a marble roller coaster for a science fair! Your goal is to create a track that allows a marble to start at the top of a hill, roll through a loop, go over a second hill, and finally land safely in a cup at the end. You have a total of 2 meters of track material to work with. How can you design your roller coaster to make sure the marble completes all these tasks? This project will require you to think creatively and apply your knowledge of physics!
As you start brainstorming, consider the different shapes and angles you can use for your track. Think about how gravity will help the marble move and how you can use energy to make it go through the loop and over the hills. You might want to sketch your ideas on paper first, and then build a model to test your design. Remember, the key is to have fun while learning about the forces at play in your roller coaster! Good luck, and let your imagination run wild!
