Curated OER
Petrology in the Gravel Pit
Students are introduced to a wide range of rock types when they examine pebbles and boulders exposed in a gravel pit. Students practice rock description and identification and categorize the rocks sedimentary, igneous, or metamorphic.
Curated OER
Glacial Geology in the Field
Students examine the origin of glaciers, how glacial sediments are deposited, and what sedimentary records of glaciation provide about source and process of glaciers in a field lab.
Curated OER
Soils are the Pits!
Students dig soil pits in order to observe soil features and the factors of soil formation and soil forming process. Students also examine the relationships among different soils in a series of soil pits.
Curated OER
Floodplains in the Field
Students measure a topographic and geologic cross-section across a floodplain using simple surveying and auguring techniques in a field lab. Students also reconstruct the history of a river system.
Curated OER
Dissolved Oxygen
Students discuss the relationships between dissolved oxygen in a stream, stream temperature, organic waste loads, and stream conditions by studying and using a model of dissolved oxygen in the stream.
Curated OER
Clean Air
Students observe gas molecules in the atmosphere absorbing the light that goes through them.
