1. Warm Up When would you use a map? What can you learn from a map?

2. The Case of the Garbage Flow
The situation:
You’re a scientific researcher and you want a $50,000 grant from the government to do some research on pollution in the Bay of Houston.
You’ve got to show the Mayor, Annise Parker, that polluted water is ruining from the streets out to the Bay so she’ll give you the cash!
The Question:
What do you think you could do to find
out which way polluted water flows when
it rains?

3. HOW ABOUT USING A…
MAP?
What??? How could a map help me know which way all that polluted water will flow?

4. So what exactly is a map?
Maps are tools that show what the earth is like.
There are many different types of maps, each of which give different information and are used for different reasons.
Today we’re going to look at two:
Political Maps and Physical Maps

5. For each map, describe what you see!
Types of Maps
Political Map
Physical Map
For each map, describe what you see!

6. Types of Maps Political Map Shows boundaries (borders)
Shows cities, states, countries, etc.
Shows shapes and sizes of regions
A boundary is a line that separates two things

7. Types of Maps Physical Map
Shows physical features (what the land is like)
Physical features could be:
Mountains
Hills
Rivers
Plains
Deserts

8. Physical Features…what the land is like!
Mountains Hills Desert
Plains Rivers

9. Alright, its GAME TIME! Two types of questions…
(1) What type of map is it? WHY?
(2) Which type of map would be best? WHY?
You will have 20 seconds with your group to discuss and decide your answer…
1 arm = political map
2 arms = physical map

10. What type of map is it? WHY?
Physical!

11. What type of map is it? WHY?
Political!

12. What type of map is it? WHY?
Political!

13. What type of map is it? WHY?
Physical!

14. What type of map is it? WHY?
Physical!

15. What type of map is it? WHY? DOUBLE BONUS!
Political!

16. Which type of map would be best? WHY?
You want to know if there is a desert in California…
A physical map would be best because it shows landforms, and a desert is what the land is like.

17. Which type of map would be best? WHY?
You want to know which states border Texas…
A political map would be best because it shows boundaries between different places.

18. Which type of map would be best? WHY?

A physical map would be best because it shows what the land is like, and you need it to be flat.

19. Which type of map would be best? WHY? DOUBLE BONUS!
You want to compare the size of the United States and Mexico…
A political map would be best because it shows boundaries and we can compare the size of places.

20. Create a Venn Diagram: Political Maps vs. Physical Maps

21. Elements of a Map

22. What do you see on the map?
