12. Depth & Light So what do you know about light?

13. Depth & Light Can you name the parts of a light wave? Direction of wave ? http://commons.wikimedia.org/wiki/File:Simple_wave.png

14. Depth & Light Can you name the parts of a light wave? Direction of wave crest http://commons.wikimedia.org/wiki/File:Simple_wave.png

15. Depth & Light Can you name the parts of a light wave? Direction of wave ? http://commons.wikimedia.org/wiki/File:Simple_wave.png

16. Depth & Light Can you name the parts of a light wave? Direction of wave trough http://commons.wikimedia.org/wiki/File:Simple_wave.png

17. Depth & Light Can you name the parts of a light wave? Direction of wave ? http://commons.wikimedia.org/wiki/File:Simple_wave.png

18. Depth & Light Can you name the parts of a light wave? Direction of wave amplitude http://commons.wikimedia.org/wiki/File:Simple_wave.png

19. Depth & Light Can you name the parts of a light wave? Direction of wave ? http://commons.wikimedia.org/wiki/File:Simple_wave.png

20. Depth & Light Can you name the parts of a light wave? Direction of wave wavelength http://commons.wikimedia.org/wiki/File:Simple_wave.png

21. Depth & Light Different wavelengths produce different colors. http://commons.wikimedia.org/wiki/File:Colors_and_wavelengt hs.png

22. Depth & Light Sunlight, is white light. It has all wavelengths & colors. http://commons.wikimedia.org/wiki/File:Colors_and_wavelengt hs.png

23. Depth & Light We can use a prism to separate colors by wavelength. http://commons.wikimedia.org/wiki/File:Light_dispersion_conceptual_waves.gif

24. Depth & Light What is the order? ROY G. BIV http://commons.wikimedia.org/wiki/File:Light_dispersion_conceptual_waves.gif

25. Depth & Light When light hits a material like water it is: Reflected, Absorbed, or transmitted. incident ray reflected transmitted absorbed

26. Depth & Light What is the color of water?

27. Depth & Light What is the color of water? BLUE

28. Depth & Light What is the color of water? BLUE What happens when light passes through a blue material?

30. Depth & Light What happens when light passes through a blue material? Every color but blue is absorbed Absorbed light transmitted light

31. Depth & Light So what happens to color at different depths of the ocean? Materials : black felt represents the aphotic zone square felt pieces in assorted colors (ROY G.BV) Blue plastic “goggles” to represent layers of water

32. Depth & Light PROCEDURE: Place black felt with color pieces face-up. Add one blue layer at a time in front of your eyes. Put an “X” in the box for every color you can see.

33. Depth & Light - (copy the table) layersROYGBV 0 1 2 3 4

34. RESULTS: What color (s) disappears with 1 layer? 2? 3? Is there any color which did not disappear? layers ROYGBV 0 1 2 3 4

35. Depth & Light Some color’s travel deeper, due to shorter wavelength. Violet gets scattered by water. http://disc.sci.gsfc.nasa.gov/edu cation-and- outreach/additional/science- focus/ocean- color/oceanblue.shtml

36. Depth & Light How does that affect the organisms that live in the ocean?

37. Depth & Light PROCEDURE: Have your partner randomly distribute pieces on the reverse side of the black felt. (Don’t peek!) Put on your goggles to simulate the Desphotic zone (3 layers).

38. Depth & Light PROCEDURE: Grab the first 10 pieces you can see. (no feeling around!) Record results. Repeat for your partner. Total your results.

39. Depth & Light PROCEDURE: (copy the table) redorangeyellowgreenbluevioletblack you partner total

40. Depth & Light RESULTS? So what were the easiest colors to find? Which colors were rarely picked up? redorangeyellowgreenbluevioletblack you partner total

41. Time to show what you have learned.

44. What colors give animals in the ocean the best camouflage? RED? ORANGE? YELLOW? GREEN? BLUE? VIOLET? BROWN? ?

45. What colors give animals in the ocean the best camouflage? RED? ORANGE? YELLOW? GREEN? BLUE? VIOLET? BROWN? 1) Design your own camouflage pattern

46. What colors give animals in the ocean the best camouflage? RED? ORANGE? YELLOW? GREEN? BLUE? VIOLET? BROWN? 1) Use data from your experiments to design your own camouflage pattern 2) Write a paragraph describing your camouflage pattern. Use data from your experiment to explain why you chose the colors in the pattern.
