Presentation Transcript

  1. Warmup1/17/13 • Describe the walk shown in each graph. • If you can, give the recursive routine.

  2. 3.3: Time-Distance Relationships Pages 172 - 177

  3. Learning Target • By the end of section 3.3, I will be able to tell what different time-distance graphs mean.

  4. Where is this stuff used? • Time-Distance graphs are created by motion sensors. • Where are motion sensors used? • Police officers use them to stop speeders. • Security systems use them to stop bad guys. • What are some other examples?

  5. What is Happening? • What are the following graphs describing if the motion sensor is at (0,0)?

  6. Investigation 3.3: Walk the Line • In investigation 3.3, we are going to interpret some time-distance graphs and model some time-distance graphs with a motion detector. • First, interpret graphs in steps 1  3. • After you complete steps 1  3, bring it to Mr. Schaner to check and get a motion detector to do steps 4 and 5.

  7. Investigation 3.3: Steps 4  5 • Your group will need: • Graphing calculator • Motion sensor • Directions: • Your group will try (it won’t be perfect) to create each graph a in step 1 with the motion sensor. (Use the Application “EasyData”) • Do it until you have a good match. • Rotate jobs and try to create graph b. • Rotate jobs and try to create graph c. • When you are finished with step 5, each person needs to create their own creative story of each graph (What could be happening?).

  8. Groups

  9. Did I Get That? – 3.3 • Write a set of walking instructions for the following graph (recursive routine). • Create a creative story to mimic the graph.
