WK 7 Light Energy II

Student should be able to:
(1) describe how we see things.
(2) explain the meaning of dispersion and use it do interpret the rainbow.

(1) Vision.
(2) Dispersion and rainbow.
Teacher: (1) Guides student to identify major parts of the eye and how vision occur. (2) Guides student to use a prism to show dispersion of light. (3) Uses the rainbow as an example of dispersion of light by raindrops in place of prism.
Students: (1) Identify parts of the eye and relate vision to refraction.
(2) Observe colour of light separated by prism and interpret rainbow as
raindrops causing dispersion.
