Your
Task:
You will need to complete at least 5 of
the Light Activities listed below and record your results in your Lab Notebook.
(Click on the highlighted words for directions.)
ACTIVITY 1: REFLECTION OF LIGHT
Reflection occurs when light or any other wave bounces off an object.
REFLECTION
enables you to see objects that don't produce their own light.
ACTIVITY 2: SCATTERING OF LIGHT
Scattering is the release of light energy by particles that have absorbed
extra energy. Light from a flashlight is SCATTERED
out of the beam by air particles. Translucent materials scatter light as
it passes through.
ACTIVITY 3: ABSORPTION OF LIGHT
Absorption is the transfer of energy carried by light waves to particles
in matter. You cannot see through
OPAQUE objects because light cannot pass through them. Opaque materials
reflect and/ or absorb all light waves.
ACTIVITY 4: TRANSMISSION OF LIGHT
Transmission of light is the passing of light through matter. The light
that reaches your eyes is transmitted through air. TRANSPARENT
materials
allow light to pass through.
ACTIVITY 5: REFRACTION OF LIGHT
The bending of light due to a change in its speed is called REFRACTION.
When light passes from air (less dense) to water (more dense) it slows
down. Passing white light through a PRISM
separates or refracts the light into different colors.
ACTIVITY 6: Primary Colors- Additive and Subtractive
- from the Ontario, Science Centre, in Toronto, Ontario,
Canada
Primary Colors:
Additive colors - are red,
blue and green.
- for color projection.
Computer displays, TV sets have these three pixel colours - (AKA Pixel
elements)
Try mixing these colors (colours) Try
mixing additive colours! - requires
shockwave plugin from macromedia.com
Subtractive colors - are yellow, cyan - (light
blue) and magenta (light purple)
Artists paint with subtractive colors. - for painting.
Try mixing these colors (colours) Try
mixing subractive colours! - requires
shockwave plugin from macromedia.com
ENRICHMENT ACTIVITIES:
Create a WORDSEARCH
or CROSSWORD PUZZLE to test your understanding of the new terms you
learned.
Create a Power Point Presentation on light. (No more than 5 slides)
After
you have written your results in your lab notebook, take the short Quiz
about Light.
How did you do?
