Goal: The purpose of this activity is to familiarize you with describing and graphing position over time graphs through the use and experimentation of motion sensors. Procedure: Step 1 Reset Step 2 check one of the challenges Step 3 start time Step 4 click on the group of kid and move them Step 5 Try to see if you can direct the kids movement to create a graph that resembles the challenge that you pick Step 6 Reset and try again
What is the most important difference between the graph made by walking away slowly and the one made by walking away more quickly? What is the most important difference between the graph made by walking away and the one made by walking toward the starting line? Describe the movement that was used to create the best graph for ChallengeA. Describe the movement that was used to create the best graph for ChallengeB. Describe the movement that was used to create the best graph for ChallengeC. Describe the movement that was used to create the best graph for ChallengeD.
