### Contents List

#### Activities

Topo Map Tidbits
Students are introduced to topographic maps and learn basic map colors, symbols, and lines. They complete worksheets that focus on topographic map symbols and colors and then locate examples of these symbols on topographic maps. Click here for Visual Resource: Reading Contour LinesClick here for Visual Resource: Common Topo Map Colors and Symbols.

Topo Bingo
Students become familiar with topographic map symbols through a fun, bingo-like game using portions of different topographic maps. .

Stream Order
Students learn how to determine stream order using topographic maps and then use this knowledge to complete worksheets and determine stream order on topographic maps.  Click here for Visual Resource file,  Leboeuf Creek KeyElk Creek KeyLittle Conneauttee KeyMackey Run KeyTemple Run KeyWolf Run Key

Stream Length
Students learn how to determine stream length on a topographic map using a map wheel or string. Worksheet

Topography
Students learn about contour lines, elevation, and land forms in the context of watershed topography via three-dimensional models and visual aids. They then use this knowledge to complete worksheets and drawings of topographic maps. Click here for Visual Resource, click here for Contour Model Keys.

Students use map wheels, topographic maps, reading elevation and contour lines and graphing skills to determine stream gradient. Stream Gradient Blank Graph Sheet and Resources

Watershed Delineation
Students use prominent topographic map features to delineate the boundaries of a watershed. Click here for Visual Resource (Figures 1 – 7.) and Contour Model Map

Watershed Area
Students learn three methods to determine the area of a watershed on a topographic map and then practice these methods on worksheets or using topographic maps. Planimeter Handout and Graph PaperWatershed Area Calibration Sheet

Land Use in Watersheds

Students use topographic maps to complete a worksheet focusing on the potential effects of land use in watersheds.

One Hilltop, Three Major Watersheds!
Students use skills from other Topographic Map Module activities to pinpoint the one hilltop from which runoff flows into three different major Pennsylvania watersheds. Click here for Visual Resource.
