The program will give you some directions. Read them, then press Enter. You will be given a graph of distance over time. Your goal is to match this graph by moving forward or backwards while pointing the CBR at a wall.
Look carefully at this graph. Think about what you will need to do to match the graph. When you are ready, press Enter to begin. Make a copy of the original graph and the result of your attempt to match that graph.
Each member of your group should attempt to match at least three different graphs. Sketch each graph and your attempt to match it. Summarize how you would match different aspects of a graph. What should you do when the graph is going up? What should you do when the graph is going down? What should you do when the graph remains horizontal?
