Question 1
1.
Both materials are emitted to a cloth sheet during scientific testing and their outcomes are measured. If Laser 2 is absorbed by the cloth would you expect the cloth to change? What evidence do you have?
CFS:
Accurately identifies the type of light reactions that cause changes in objects
Accurately describes the relationship between wave properties and outcomes
"I think that laser 2 (will / will not) change because ..."
Question 2
2.
Both materials are emitted to a cloth sheet during scientific testing and their outcomes are measured. If Laser 2 is absorbed by the cloth would you expect Laser 3 to do the same? What evidence do you have?
CFS:
Accurately identifies the type of light reactions that cause changes in objects
Accurately describes the relationship between wave properties and outcomes
I think that if laser 2 is absorbed, then laser 3 (will / will not) aborb. I think this because ..."
Question 3
3.
How can you adjust the wave properties (wavelength/amplitude) to change the color of light from black to green?
CFS:
Accurately identifies the type of light reactions that cause changes in objects
Accurately describes the relationship between wave properties and outcomes
"I think that I can change the wave to green by ... because ..."
Question 4
4.
How can you adjust the wave properties (wavelength/amplitude) to increase the intensity of the light while keeping the color black?
CFS:
Accurately identifies the type of light reactions that cause changes in objects
Accurately describes the relationship between wave properties and outcomes
"I think that I can increase the intensity of light by... because ..."
Question 5
5.
Assuming that light from the black laser is transmitted by materials, do you think the wave can cause materials to change? What evidence do you have to support your answer?
CFS:
Accurately identifies the type of light reactions that cause changes in objects
Accurately describes the relationship between wave properties and outcomes
"I think that the laser (will / will not) cause objects to change because ..."
