Practice:
The Australian Health Alliance is counting on you to help people understand how skin cancer occurs. Use the Modeling Tool activity: The Cause of Skin Cancer on the next page to show your thinking, following the steps below. When you are finished, add a written explanation of how light from the sun can cause skin cancer.

Question 7
7.
Why can some types of light cause skin cancer but others cannot?
CFS:
Accurately identifies how light interaction change objects
Accurately describes the relationship betweenlight interactions and changes in objects
"Some types of light can cause skin cancer while other cannot because light is (absorbed/transmitted/reflected).
This is important because (absorbed/transmitted/reflected) cause changes while (absorbed/transmitted/reflected) do not."
