### Map Skills

1. 1. Measuring Planet EarthHow do you know where you are going if you don’t know where you are?
2. 2. Measuring Planet Earth∗ Lots of different maps have been created throughout history∗ Why do you think people invented maps?∗ Problem Solving like a human: ∗ If you wanted to travel somewhere else what two pieces of information would be ABSOLUTELY necessary?
3. 3. Measuring Planet Earth∗ Hopefully you said… ∗ Where they live ∗ How far away it is∗ This is where the lines of longitude and latitude come in∗ If you turn your world into a grid with units of measurement you can figure out where you are going and how far it will be
4. 4. Measuring Planet Earth∗ What is a grid and how is that helpful?∗ When using a grid you need to know how to use coordinates∗ (horizontal, vertical)∗ The star is located at (4,D)
5. 5. Using a Grid∗ Before we move on… Try practicing using a grid system
6. 6. Measuring Planet Earth∗ Lines of latitude run horizontally around the planet∗ Lines of longitude run vertically around the planet∗ To measure something, you need to have a starting point∗ Lines of latitude and longitude have 2 starting points∗ The Equator and the Prime Meridian∗ They divide the planet into hemispheres
7. 7. Mapping Planet EarthWestern Hemisphere Eastern Hemisphere
8. 8. Measuring Planet Earth∗ Label and darken the Prime Meridian and Equator on your map
9. 9. Measuring Planet Earth∗ If you’re going to have a numbered grid, you need to determine your units of measurement∗ To precisely locate points on the earths surface, degrees longitude and latitude have been divided into minutes () and seconds (").∗ There are 60 minutes in each degree (it takes one hour to go from one line to the next parallel)∗ Each minute is divided into 60 seconds. Seconds can be further divided into tenths, hundredths, or even thousandths.
10. 10. Measuring Planet Earth∗ Before you can go very far with your grid, you need to know direction∗ A Compass Rose will tell you what direction you are headed in from a given location ∗ North ∗ South ∗ East ∗ West
11. 11. Measuring Planet Earth ∗ For example, the U.S. Capitol is located at 38°5323"N , 77°0027"W ∗ In other words: 38 degrees, 53 minutes, and 23 seconds north of the equator and 77 degrees, no minutes and 27 seconds west of the meridian
12. 12. Review∗ What are latitude and longitude and what are they used for?∗ What is a hemisphere?∗ Explain what the equator and prime meridian are used for
13. 13. Using Latitude and Longitude∗ Let’s practice finding places on planet Earth using latitude and longitude
14. 14. Mapping Planet Earth∗ Now that we know how to measure distance on Planet Earth let’s figure out how to MAP it∗ Problem Solving ∗ How do you turn a round object into a flat one?
15. 15. Mapping Planet Earth∗ Map makers run into the same problems as you do when trying to convert the globe into a flat map∗ They have come up with several different Map Projections that try to show the world accurately but each projection has its advantages and disadvantages∗ Turn to page 107 in your Atlas
16. 16. Mapping Planet Earth∗ Now you know the basics about how to turn Planet Earth into a flat map with a grid system that helps us find our way around∗ Let’s look at the major landmasses and waterways that cover Earth’s surface Continents and Oceans!
17. 17. Mapping Planet Earth∗ There are many different kinds of maps that we use for many purposes but they all have one or more of these basic∗ Parts of a Map ∗ Map Key ∗ Scale ∗ Compass
18. 18. Parts of a Map∗ A Map Key tells you what the symbols on a map represent ∗ In your Atlas find an example of a Map Key and point to it∗ A scale will show how to convert the distances on your small map into real world distances ∗ In your Atlas find an example of a Scale and point to it∗ A Compass Rose will tell you the direction – North, South, East or West ∗ In your Atlas find an example of a Compass Rose and point to it
19. 19. Purposes of Maps∗ Maps can be used to serve many different purposes∗ Let’s look at some examples ∗ Physical Map – tells you the physical geography ∗ Political Map – tells you the political boundaries of countries ∗ Special Purpose Map – tells you almost anything you can imagine
20. 20. Purposes of MapsIn Your AtlasUse pages 38-49 to demonstrate yourunderstanding of different kinds of maps
