Transcription de la présentation

  1. Ramp It Up

  2. Ramp it up • Learning targets: • I can explain what happens when a force is applied to an object. • I can categorize forces. • I can name a force that is influencing an objects motion on a ramp. • I can explain how the weightof an object influences an objects motion on a ramp.

  3. Simon Says

  4. Motion Challenge • You will have two minutes to use the provided materials to see how many ways you can make the car move from one side of the desk to the other. • Do not use your hands to make the object move! (You may use your hands to place the object.) • Person to person. • Think about which direction the car went.

  6. What forces caused the car to move?

  7. Ramp It Up Teacher Demo car on a ramp experiment

  8. Design an experiment • What force is causing my car to move down the ramp?* • What parts of my experiment could I change to determine what properties influence the motion of an object moving down a ramp? Which of these ideas will help us with the last learning target?

  9. Design an experiment • Question to investigate: • When a matchbox car is traveling on a ramp, how will increasing the weight of a matchbox car change the distance the car travels? • Make a hypothesis

  10. Design an experiment • Experimental Design • In a well designed experiments, how many things can we change? • What parts of the experiment should we keep the same?

  11. Design an experiment • Do experiment • Enter data in Microsoft Excel • Create a graph

  12. Design an experiment RERUN Recall: Summarize what you did in the lab. Explain: Explain the purpose of the lab. Results: Describe the results of the lab and what they mean. Uncertainties: Describe what you are still unsure about. New: Name two new things that you learned from this lab.

  13. Further Investigation • Try it again testing other ideas suggested by students. • Put it all together in a challenge. • Make the car go 1 meter. • Use what they learned in all experiments. • Make adjustments. • Average five tries. • Closest to 1 meter wins.

  14. Lessons from experience • Use a track so the car moves in a straight path. • Extra set of hands or station activity. • Expect lots of human error. • Test speed by using stopwatch • Remind students we are measuring distance. • Make sure students are not pushing car. • Make sure ramp is taped to the top book. • Use new cars. • Discuss how to take turns.
