1. Topic-
 Topographic Maps
2. Content-
 topographic maps, contour line, contour interval, index contour.
3. Goals: Aims/Outcomes-
 1.Read a topographic map and a geologic map for evidence provided on the maps.(SS-6.7.F) 2.Construct and interpret a simple scale map (SS-6.7.F)
4. Objectives-
 1. Explain how elevation, relief, and slope are shown on topographic maps. 2.Explain how a topographic map is read.
5. Materials and Aids-
 Model demo materials (clay, pencil, butter knife, blank piece of paper), Prentice Hall Earth Science textbooks (1.4-p.28-31), science notebooks, 1.4 Review and Reinforce handouts (from Teacher Resource book), Discovery Channel School DVD-Video Field Trip: Mapping Earth's Surface, paper for KWL notes.
6. Procedures/Methods-

A. Introduction-

 Teacher will build background knowledge by providing a topographic map, and asking students to identify familiar features. Students will be asked to point out contour lines and explain how these lines show changes in elevation. The teacher will then draw a series of three concentric circles on the board and will draw the number 10 on the largest circle 20 on the middle circle, and 30 on the innermost circle. The teacher will ask the students what the numbers suggest about the shape of the feature. (Students should infer that the numbered circles represent a hill as seen from above)

B. Development-

 Using the Elmo Camera and Projector, the teacher will provide a visual aide for contour lines by using clay to represent a model of a mountain. After using a pencil to create a hole through the middle of the mountain and 6 horizontal "rings" around it, the teacher will use the butter knife to cut through the rings of each section. Starting from the smallest, top portion the teacher will place each piece on a paper and trace around them, creating contour lines. The teacher will explain how the closed lines represent the difference in elevation.

C. Practice-

 1.Students will be given the 1.4 Review and Reinforce handout. After directions are explained, students will spend the next 5 minutes with their elbow partners answering #1-6 (identifying the commonly used symbols in topographic maps) 2.The students will come back together and in a whole-group, direct-instruction design to complete #7-10. The teacher will guide students, using the projector.

D. Independent Practice-

 The students will then work in an independent setting, as they complete the last portion (vocabulary) of the review handout.

E. Accommodations (Differentiated Instruction)-

 1. Students may use the textbook and/or their chapter notes in their science journals. 2. Students that struggle with reading grade-level texts and/or taking class notes during lessons will be provided with copies of the class notes. 3. Students that require extra assistance will work with the instructional aide/teacher for extra support.

F. Checking for understanding-

 1.Prior to the Video Field Trip: Mapping Earth's Surface, students will use the back of the 1.4 Review and Reinforce handouts to create "KWL" columns. 2. The Students will be asked to orally explain what they will put in the "K" (or "What I Already Know") column. 3. Once the class generates ideas for the "K" column, the students will be asked to create questions for the "W" (or "What I Want to Learn") column. 4. Prior to view the film clip, the teacher will ask students to reflect on this question while they're watching: How is GPS being used to create more accurate maps?

G. Closure-

 Students will view the Video Field Trip: Mapping Earth's Surface to review/enrich the lesson's concepts.
7. Evaluation-
 1. Once the film clip is over, the teacher will ask the students if they can now answer the reflection question. The class will discuss this and any other new information that they gathered from the video. 2.This discussion will facilitate the completion of the "L" (or the "What I Learned") column of the KWL notes.
