April 2012 5th Grade: Unit- Landforms Duration: 45 Minutes Landforms: Investigation – Bird’s Eye View Objective: Students will synthesize their knowledge of topographic maps with their knowledge of landforms from the previous unit by making comparisons between the topographic map and the aerial photograph of Mt. Shasta. Materials needed: For each group Topographic map poster of Mt. Shasta Aerial photograph of Mt. Shasta Foam mountain replica of Mt. Shasta Hand lenses Student Worksheet For the teacher: Post-it “flags” Teacher Preparation: Make copies of worksheet Preassemble the foam mountains to save time and ensure correct orientation (the students have already had the opportunity to assemble and dissemble these foam mountains multiple times) Resources: 1. FOSS Teacher’s Guide: Landforms Procedures: I. Opening (5 minutes) To allow more time for exploration, begin with a very brief review of the vocabulary terms covered in the previous lessons Topographic map / Profile map / base / peak / contour internal / contour lines / elevation / sea-level / benchmark II. Activity (30-35 minutes) Tell the class that today we are all going to be surveyors (define term) Divide the class into 8 groups (roughly 3 students per group) and distribute materials (topographic map, aerial photo, foam mountain, worksheet) Have students orient the foam mountain, topographic map, and aerial photo so that the peaks and directions of ridges and canyons are matching Students will use the topographic maps to identify locations in the photograph Write the list of following locations on the board and ask them to find each one (distribute post-it flags and ask students to mark the different locations) Shastina The peak of Mt. Shasta Wintun Glacier North Gate Hidden Valley Mud Creek Glacier After they have identified these locations, begin to answer the questions on the worksheet Instruct the class to work as a group and try thoroughly to answer the questions on their own before asking for help from the teacher III. Closing/Wrap Up (5-10 minutes) Ask students to take out the word banks we created at the end of the last lesson and add the following entries: Aerial photograph = a photograph of the earth’s surface taken from an airplane or spacecraft flying above the earth Scale = describes the ration between a measured distance on a map to the actual distance in the real world. Surveyor = a person who measures and marks the distance, elevation, position, and boundaries of land areas Bar scale = a ruler line on a topographic map that shows the scale Representative fraction = tells the scale of a map as a ration between distance on a map to distance in the real world Student Assessment: Collect worksheet from class activity Distribute Landforms Study Guide Tell students to attempt to complete the worksheet individually before the following week’s lesson as a study aid I will distribute an answer key the following week
