Slide 1: Map Skills
Slide 2: What is a map? A map is a representation, usually on a flat surface, of the features of an area of the earth or a portion of the heavens, showing them in their respective forms, sizes, and relationships according to some convention of representation. Now what does that mean?
Slide 3: A map is a representation, A map is a drawing or model usually on a flat surface, of a round Earth on a flat surface, of the features of an area of the earth that shows the landforms (mountains, rivers, etc.) or a portion of the heavens, or part of the sky in a particular region, showing them in their respective forms, sizes, and relationships drawn to scale according to some convention of representation. using an accepted form of drawing or model.
Slide 4: Types of Maps There are three basic types of maps: PHYSICAL POLITICAL and THEMATIC.
Slide 5: Physical Maps • Physical maps show the natural features of the Earth. • Physical maps do not contain man made features. • For example, a physical map would be a map of what you would see if you were looking down on Earth from space.
Slide 6: When you look at this map, what do you see? Notice you do not see country borders or city markings. These divisions are created by people. For example, there is no actual line dividing Texas from its bordering states. Although some astronauts (with the use of binoculars believe it or not) are able to see roads, large ocean tankers, and even the Great Pyramids from space, at very high altitudes, none of these are visible and all you are left with are natural land formations.
Slide 7: Political Maps Unlike physical maps, political maps show how humans have impacted the landscape. For example, city names, roads, country borders, etc. are all part of political maps. Political maps change frequently (physical maps change very, very slowly through geologic processes) and must be redrawn often. A political map of the world that is 50 years old is no longer accurate. Wars and ethnic conflict are two major causes political maps change.
Slide 8: Political Maps
Slide 9: Thematic Maps • Thematic maps can represent a variety of information including things like climate, precipitation, vegetation, elevation, population, life expectancy, etc. • Thematic maps are generally used when you are looking at a single piece of information.
Slide 11: Creating a Thematic Map • You are now going to create a thematic map. • You will now choose the information you will represent on your thematic map. You may choose to take a poll of favorite subjects, types of music, sports, birth months, etc. Choose something you are interested in learning about. BE CREATIVE!
Slide 12: The classroom is set up in the following manner… = Student Desk
Slide 13: Now choose what you want to know… • I would like to know which pizza toppings students prefer to eat from the following list: Pepperoni, Hamburger, Cheese, or Sausage. • I will now ask the students to choose from this list of toppings and record the results.
Slide 14: Now you must choose a way to represent the information you have gathered. I have chosen to use different colors so that we may see the distribution of topping preferences.
Slide 15: For example, the thematic map of my classroom may look like this… Pepperoni Hamburger Cheese Sausage
Slide 16: According to this thematic map of the classroom, which pizza topping is the most popular?
Slide 17: Map Components Title Grid Compass Key or Legend Scale
Slide 23: To help us review basic geographic terms that are used to create grids, we will play a game called GEOrobics.
