1. I can explain light transmission through different mediums.
Light POE
I can explain light transmission through different mediums.

2. Opening: Explain the phenomenon you see in the picture.

3. Explanation
When looking at the sun through the frost patterns on the windshield of my car, I saw a well-defined yellow and red corona. The ice crystals on the window pane worked as an obstacle which diffracted the light, which means they deviated it into different directions. So the light waves can reach areas which are blocked out when following the direct way. A diffraction pattern always consists of bright and dark spaces. The dark spaces are those where waves extinct each other, while the bright areas are at the positions where the light waves add each other.

4. POE 1
Predict: How will putting a pencil in a beaker of water affect the appearance of the pencil?
Observe: Draw a picture of how the pencil looks in the beaker of water.
Explain: What type of light interaction helps to explain your observations (Diffraction, reflection, refraction, or absorption)? Why did putting the pencil in the beaker affect the appearance of the pencil?

5. POE 2
Predict: What type of light interaction will occur when you shine a light through a prism? Explain.
Observe: Shine a light through a prism. Draw your observation.
Explain: What type of light interaction helps to explain your observations (Diffraction, reflection, refraction, or absorption) Explain how what you observed occurred.

6. POE 3
Predict: How will shining a laser pointer through water affect the dot on the wall?
Observe:
1. Observe the dot on the wall as the laser pointer shines on the wall. Record your observations.
2. Observe the dot on the wall as the laser pointer shines through the water to the wall. Record your observations.
Explain: What type of light interaction helps to explain your observations (Diffraction, reflection, refraction, or absorption)? How does this light interaction explain your observations?

7. POE 4
Predict: When the laser pointer shines on the back wall, will you be able to see the beam of light between the laser pointer itself and the wall? Why or Why not?
Observe:
1. Observe the laser pointer as it shines on the back wall. What did you notice about the beam of light between the laser pointer itself and the dot of light on the wall? Record your information.
2. Now observe the beam of light between the laser pointer and the back wall after baby powder is sprinkled on the beam of light. Record your observation.
Explain: What type of light interaction helps to explain your observations (Diffraction, reflection, refraction, or absorption)? How does this light interaction explain your observations?
