You typically do this by comparing the landmarks you see to those shown on the map. To be able to use a map to find your way, you must first determine where your current location is on the map. A city map shows streets and major landmarks for that city, like hospitals and parks. For example, a state map shows cities, major roads, national parks, county lines, etc. The features of a map are dependent upon the intended use. Maps come in a variety of forms: city maps, road maps, nautical maps, topographical maps, and many others. Lesson Background and Concepts for Teachers Luckily, there is a map made just for such purposes: it is called a topographical map. With such a map, you could determine how big the mountain really is. What would be really helpful would be a map that also tells us how high the mountain is.

How is a map helpful? A map might only show an 'X' to indicate the peak (top) of a mountain, but the mountain is large and extends far beyond the actual peak. What if you were not traveling to another city but taking a trip in the wilderness? What kind of information do you think that you would need to know? (Possible answers: locations and names of trails, rivers, and mountains.) What if there was a mountain right in the middle of where you wanted to go? Most of us would think to go around the mountain instead of up and over it. But how are maps useful? What do they tell us? (Possible answers: landmarks, recreational areas and roads to travel to get to different destinations.)

By comparing what you see around you to what is on the map, you can figure out where you are and how to get to where you want to be. Maps provide an image or picture of an area with both natural and man-made landmarks. If they are going on a family vacation to the beach, how do their parents know how to get there? (Possible answer: Look at a map.) Why are they not able to use landmark navigation (identifying known landmarks to determine your location) like at home? (Possible answer: Because you do not know the relative location of landmarks if you have never been there before.)

Understand how interpreting maps is an essential skill for all types of engineeringĪsk your students how they might travel to somewhere they have never been to before.

Understand the major features of maps and compasses.

Interpreting maps is an essential skill for all types of engineers.Īfter this lesson, students should be able to: For electrical engineers, circuit diagrams serve as maps to communicate with others how to build the circuit. NASA engineers sending a robot to a planet's surface must pick a suitable landing spot (a flat area rather than a steep canyon). A civil engineer carefully examines topographic maps to decide the best location to construct a power plant for the safety of surrounding populations. Maps are an important tool for all types of engineers. Through the associated activities, students will learn how to use a compass to find bearing to an object on a map and in the classroom. Students will also learn to identify the common features of a map. The focus of this lesson is on how to read and use topographical maps. Maps are created by cartographers, and they can be very specific or very general, depending on their intended use. A navigator uses a nautical map, while an engineer might use a surveyor's map.

There are many types of maps available for both recreational and professional use. They tell us information about areas to which we may or may not have ever been. Maps are designed to allow people to travel to a new location without a guide to show the way. Making GPS Art: Draw It, Walk It, Log It, Display It!
