The Australian Health Alliance is counting on you to help people understand why the skin cancer rate in Australia is so high. Use the Modeling Tool: Ultraviolet Light in Australia and Brazil to show your thinking, following the steps below.
Goal:
Show why Australia gets more UV light than Brazil by modeling how UV light waves travel through the atmosphere above each place.
Do:
Extend each arrow showing the path of UV light as it travels through the atmosphere toward Earth’s surface. If the light hits a material in the atmosphere, show what happens to the UV light.
Use a yellow highlighter to trace the path of energy.
Annotate your model to help show why Australia gets more UV light than Brazil.

Reflection:

Which type of atmospheric gas or gasses are most helpful in reducing UV exposure to humans on Earth?
CFS:
Accurately identifies the type of light reactions that cause changes in objects
Accurately describes the relationship between wave properties and outcomes

You have been investigating why the cancer rate in Australia is so high. Use the Reasoning Tool below to connect each piece of evidence to the claim you think is accurate. Explain why each piece of evidence matters, then note the claim you think the evidence supports.
Question: Why is the skin cancer rate in Australia so high?
Claim 2: There is something different about the sunlight in Australia.
Claim 3: More people in Australia have skin that is easily damaged by light from the sun.
