1. Seasons

2. Why are they important? Understanding the world around you
Knowing where to go on vacation…

3. Many things cause seasons…
1 of them we will discuss today
Does distance from the sun cause seasons? NO!!!
By the end of the WEEK you will be able to answer the question that even Harvard graduates get stumped on

4. What causes seasons?

5. Today’s Goal
Use evidence to explain one thing that affects climate (seasons) over the course of a year.

6. Remember reading a weather graph?
Temperature over time (hours)
What did we conclude?

7. Today…. Climatograph Still temperature over time.
This time instead of hours, it’s months

8. In your groups… Think about: You will get 12 climatographs.
Classify/group/categorize the graphs.
While you are doing this pay attention to the trend in weather across the year.
Think about:
Similarities/differences between graphs
When is it summer? Winter?
How much is temperature changing from season to season? Is it a big change or a small change?

9. How did you group them?
Did you look at their seasons to group them?

10. Goal
Use evidence to explain one thing that affects climate (seasons) over the course of a year.

11. Let’s look at the Earth: Longitude and Latitude
Latitude: Distance in degrees North or South of the equator
Tropic of Cancer
Equator
Tropic of Capricorn

14. Take another look at your groups…
How did you group them?
How are they grouped on the map?
What trends do you see with their climate and their locations on the map?

16. Think about our goal: Did you meet the goal?
Use evidence to explain one thing that affects climate (seasons) over the course of a year.
Did you meet the goal?
1. What were your climatographs showing?
2. What things affected the seasons on your climatographs? – think about the map
3. What evidence do you have for your inference?

17. Let’s put it all together…
On a piece of paper, use one piece of evidence to explain one thing that affects seasons.
“Seasons can be affected by______. This is shown by ______.”
“__________ shows that seasons can be affected by_______.”

18. Today: What affects seasons? Tomorrow: Why does it affect the seasons…
