 Activity 1

Make a guidebook to help others identify animals and/or plants in the  Canadian wilderness. Future activities in this unit will guide you as to which animals to add to your guidebook.

Brian encounters bears, moose, turtles, skunks, porcupines, wolves, and various fish and birds in the wilds of Canada. Learn about these and the plants that he might see as well.Draw each animal and/or plant. Write a short description for each drawing. Bind these drawings together to form your book.

 Activity 2

When a person suffers a serious injury the body may react by going into shock.

 

Activity 3

Light Refraction - At first Brian was unable to catch the fish because the water made them appear in a different location than where they really were. This is due to light refraction in the water. Below is a demonstration of how light refraction works.

Things To Try

  1. The incident angle can be varied from 0 to 85 degrees. (In 5 degree increments using the +-5 buttons.)
  2. The index of refraction of the first medium is fixed at n=1.00.
  3. The index of refraction of the second medium can be varied from n=1.00 (for vaccuum) to a maximum of n=2.42 (for diamond). (Selectable by pulldown menu.)
  4. The incident wavelength (and color of light) can be varied from a minimum of 475 nm (blue light) to a maximum of 650 nm (red light). (In 15 nm increments using the +-15 buttons.)
  5. Notice that the refracted wavelength is shortened by a factor of 1/n.
