  • Depth & LightSo what do you know about light?

  • Depth & LightDifferent wavelengths produce different colors.http://commons.wikimedia.org/wiki/File:Colors_and_wavelengths.png

  • Depth & LightSunlight, is white light.It has all wavelengths & colors.http://commons.wikimedia.org/wiki/File:Colors_and_wavelengths.png

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

  • Depth & LightWhat is the order?ROY G. BIVhttp://commons.wikimedia.org/wiki/File:Light_dispersion_conceptual_waves.gif

  • Depth & LightWhen light hits a material like water it is:Reflected,Absorbed,or transmitted.incident rayreflectedtransmittedabsorbed

  • Depth & LightWhat is the color of water?

  • Depth & LightWhat is the color of water?BLUE

  • Depth & LightWhat is the color of water?BLUE

    What happens when light passes through a blue material?

  • Depth & LightWhat happens when light passes through a blue material?Every color but blue is absorbed

  • Depth & LightSo 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

  • Depth & LightPROCEDURE: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.

  • Depth & Light - (copy the table)

    layersROYGBV01234

  • RESULTS:What color (s) disappears with 1 layer? 2? 3?Is there any color which did not disappear?

  • Depth & LightSome colors travel deeper, due to shorter wavelength.Violet gets scattered by water.http://disc.sci.gsfc.nasa.gov/education-and-outreach/additional/science-focus/ocean-color/oceanblue.shtml

  • Depth & LightHow does that affect the organisms that live in the ocean?

  • Depth & Light

  • Depth & LightPROCEDURE:

    Grab the first 10 pieces you can see. (no feeling around!)Record results.Repeat for your partner.Total your results.

  • Time to show what you have learned.

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

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

  • 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 pattern2) Write a paragraph describing your camouflage pattern.Use data from your experiment to explain why you chose the colors in the pattern.

    Allow students to volunteer their answer choices, then click again to show camouflage pattern and discuss.Allow students to volunteer their answer choices, then click again to show camouflage pattern and discuss.Allow students to volunteer their answer choices, then click again to show camouflage pattern and discuss.You should visit the website noted and download the video clip. Reformat it as WMV and insert the clip into this presentation before using it in class.Ask the students, what about the pictures gave it away.sample answers: the light in A, the darkness of BAsk the students, what about the pictures gave it away.sample answers: fish in the disphotic often are bioluminescent, only fish that live near the surface would have bright, colorful patternsAsk the students, what about the pictures gave it away.

    sample answers: only a crab who lives in the light would need a camouflage pattern, animals that live without light often do not have protective camouflage since nobody can see them

    Name each wave part, give the students an opportunity to think about and respond to the question before proceeding.Instruct the students to begin their notes by copying the wave patterns and labeling the parts.Allow students to respond.Place a piece of blue plastic in front of your projector. When the screen appears blue, ask the students why it appears blue.It's a good idea to have the materials at the student desks before beginning the presentation. A common technique is to place the lab materials in a cheap, plastic shoe box at the desks, before students enter the class.Have students copy the question into their notes.Have students copy the procedure into their notes.Have students copy the data table into their notes.Then allow them time to try the experiment with their partner. When you judge they are ready to go on (10minutes+/-) go to the next slide.Discuss the class results, calling on volunteers to share their results. Guide the students to answers for the questions posed. You may want to write them on the board and have the students copy the questions and answers into their notes.

    RESULTS WILL VARY: depending on the shade of blue plastic you make your classroom goggles from. What color (s) disappears with 1 layer? 2? 3? generally the students will report that red disappears first with orange and yellow following. Is there any color which did not disappear? Some students may report that blue and even green do not disappear. Again some variation can be expected due to differences in the materials used to construct your lab materials.

    Next mini-lab, have students copy question.Students should copy the procedure into their notes.Students should copy the table into their notes. Then allow them time to try the experiment with their partner. When you judge they are ready to go on (10minutes+/-) go to the next slide.

    Students should copy the table into their notes. Then allow them time to try the experiment with their partner. When you judge they are ready to go on (10minutes+/-) go to the next slide.

    RESULTS WILL VARY- but in general very few pieces of red or black felt will be picked up, some orange and yellow, while lots of green and blue piece a selected. So what were the easiest colors to find? blue & green Which colors were rarely picked up? red & black

    repeat the intro sequencerepeat the intro sequencerepeat the intro sequenceIt is advisable to have the students write down the instructions.Students should incorporate shades of red (orange and yellow are also good) and black into their pattern.The paragraph should accurately describe the pattern they designed, use data (preferably numerical) from their experiments to support their color choices. Extra points could be assigned for referencing aquatic organisms which use these colors.
