Objective: SWBAT identify how light carries energy in different natural systems by analyzing graphs and light from artificial light sources.
Do Now:
Question 1
1.
The sun causes changes to things on Earth. Think of an object you have observed before and after it was left out in the sun. Describe how it changed.
Examples:
1.Apple- in the sun an apple turns brown and can shrivel up
2.Water- in the sun water increases water temperature
Guided Notes:
Vocabulary:
1. Energy: the ability to make things move or change
Question 2
2.
Video:
Light from the sun causes changes to things on Earth. What is an example of an object you have observed that changed when left out in the sun?
Question 3
3.
When light hits a material, different things can happen. Something left in the sun can become warm or even change color. How do you think light from the sun causes materials to change?
Question 4
4.
Reflection: How can you identify when energy is taken in by light?
CFS:
Accurately identifies how light energy impacts other objects
Accurately describes the relationship betweenlight energy and changes in other objects
Practice:
Question 5
5.
What does the darkest color represent on the table above (rate of Skin Cancer)?
Question 6
6.
What does the lightest color represent on the table above (rate of Skin Cancer)?
Question 7
7.
Which continent has the highest Skin Cancer rate?
Exit Ticket:
Identify if energy caused the changes in the systems.
Question 8

Identify the correct definition of energy.
Question 9
9.
What evidence can you find to identify which system above has taken in energy?
CFS:
Accurately identifies how light energy impacts other objects
Accurately describes the relationship betweenlight energy and changes in other objects
