Question 1
1.
Maya wonders which types of light could heat up a sheet of aluminum. The table below shows what happens when different types of light hit the aluminum.
Explain why will neither type of light cause the aluminum to change/heat up?

In an experiment Aidan is trying to identify how different types of color interact with different colors of paint. Below shows the 4 different ways light can interact with a material. Aidan wants the paint to last as long as possible without changing, fading.

Describe what evidence you can find to determine which colors would be best to use and which would be worst?
CFS:
Accurately identifies the differences in light sources
Accurately describes the relationship between wave properties and outcomes'
(Think: what is the only type of light interaction that can cause an object to change?)
