1 Flickr, Ken Lund Welcome to: Zipline Mathematics Focusing on: – STEM – Algebra I – Inquiry – Modeling

2 Flickr, Ken Lund Real-life Problem Holly Mountain needs more revenue – Money from skiing in winter is not enough

3 Flickr, Ken Lund Board of Directors They have approved the use of the slopes for zipline use in the summer

4 Flickr, Ken Lund Problem – Part 1 Insurance company says the usual zipline equipment not safe enough

5 Flickr, Ken Lund Problem Part 2 You must create a zipline carrier that: – attaches to the existing zipline – travels within a certain range of speed – provides a smooth, consistent descent – is safe – is easily used

6 Flickr, Ken Lund Modeling Since we are not at the resort: – Fishing line represents zipline – Ping-pong ball represents a person – Minimal speed is 20 inches per second – Maximum speed is 60 inches per second

7 Flickr, Ken Lund How can we calculate speed? What formulas could be helpful?

8 Flickr, Ken Lund distance = rate x time

9 Flickr, Ken Lund Low Cost is Good Materials UsedCost for MaterialsMoney Spent Kabob Stick$10 $ Duct Tape$12/inch $ Masking Tape$6/inch $ Straw$13 $ 3 by 5 card$18 $ Paper Clip$25 $ Washer$10 $ Total Spent $

10 Flickr, Ken Lund Engineering Design Process What is it?

11 Flickr, Ken Lund Engineering Design Process

12 Flickr, Ken Lund Identify a problem Research and Brainstorm Several Solutions Design and Test Evaluate and Communicate Redesign Engineering Design Process

13 Flickr, Ken Lund A successful design… meets the design criteria. Is NOT too expensive.

14 Flickr, Ken Lund Criteria Reminder You must create a zipline carrier that: – attaches to the existing zipline. – travels at least 20 inches/second. – travels no faster than 60 inches/second. – provides a smooth, consistent descent. – does not allow harm to ping-pong ball. – is easily used.
