WOSAT Presentation
Topography, Bathymetry, and an introduction to Earth’s processes

2. Overview Ansonia High School– 10th grade P.S. Content Standards—
Grade 9-10 Earth Sciences, Benchmark F
Indicator 8 (emerging issues)
Grade 9-10 Scientific Inquiry, Benchmark A
Indicators 3 and 5 (const. models / present.)
Grade 9-10 SWOK, Benchmark B
Indicator 7 (building on previous info.)

3. Overview Instructional strategy: Topography Pre-test
The “Hook”– stereoscopes
Activity– clay models
Activity– box topography
Activity– Elk ridge
Bathymetric “black box”

4. Stereoscopes

5. Clay models and Box topo.

6. Bathymetric Activity

7. Assessment Performance based Clay model Contour map Graphs
Cardboard model
Scatter plot
Bathymetric map
Standard written
Pre-tests
Numerous quizzes
Unit exam

8. Data Results Clay/cardboard models– basic understanding of contour
Contour map/graph—higher level concepts of what contour lines represent
Bath. map/scatter plot– illustrated how contour maps are generated
Quiz/Test– show a better grasp on topography and earth’s processes overall

9. Data Analysis Pre-test . . . Post-test . . .
Showed some had ‘OK’ mapping / graphing skills, but lacked in overall understanding of topography
Post-test . . .
Students showed a greater depth of knowledge on the written response items

10. Reflections Modifications to pre-test
Diversity in the complexity of contour maps
Modifications to the structure of the tests
2 column, charts and graphs, multiple question items, etc.
