  1. Math in Motion Olds High School Natalya Nicholson VC Session 3 April 27, 2006

  2. Grizzly Bear Protection Project • Tell me more… • What is the purpose of your project? • What are you hoping to learn from it? • Did you run into any unexpected problems? • Why is it important to study bear habitat? • Can you make a difference to the future of Canadian parks and wilderness?

  3. Something About Mary… • Tell me about your bears • Mary • Scott • Snoopy • Katie • Duncan

  5. Rocky Mountain Foothills Habitat • Tell me more… • Describe the habitat of you bears. • What are important features for bear habitat? • Are the requirements different for different bear species? Bears of different gender? • What risks do humans pose to bear habitat?

  6. Habitat Area • How can you use math to describe a bear’s habitat? • What other methods could you use?

  7. R Bear Habitat Area • Some Geometry… • Area of a Circle: π x R2 • Circumference of a circle: π x 2 x R • How might we define the location of the center of the circle? Statistics!

  13. Foothills Model Forest Grizzly Bear Research Program • Currently use GPS collars to track bears. • Understand habitat and resource needs.

  14. Camera Development

  15. What recommendations would you make to the Government to protect the habitat of your bears?

  16. Government considerations? • What will the government have to consider when it evaluates your recommendations?

  17. Remote Sensing http://www.geomatics.ucalgary.ca/%7Ehabib/research_areas/r_areas_new_sensor_modeling_and_integration.html

  18. 3-D Shapes http://argyll.epsb.ca/jreed/math9/strand3/3107.htm

  19. Shape of the Beam • When GPS sends a signal to the Earth, what shape does the beam make?

  20. What area of the ground does the beam cover? Area = πr2 Perimeter = 2πr

  21. What area of the ground does the beam cover? Area = b2 Perimeter = 4b

  22. How can remote sensing with satellites help you learn more about bear habitat?

  23. Topics for next time?
