Deposition and Erosion Using Google Earth and Landsat by David Schklar

Agenda

david_schklar — 2015-12-04 19:53:27 UTC

•Examine Ohio Learning Standards (OLS) for Sedimentation and Deposition.

•Use of “River Table” to demonstrate the processes.

•Show examples using photos from Ohio Department of Natural Resources (ODNR), USGS's Landsat, and Google Earth of erosion, sedimentation, and deposition.

•Break out into groups to research and share other examples using the technology.

Grade 2 ESS Standards

david_schklar — 2015-12-07 21:59:56 UTC

Standard: The atmosphere is made up of air.

Elaboration:

- Wind can change the shape of the land (e.g. sand dunes, rock formations).

- Weather events that are related to wind (e.g., tornadoes, hurricanes) are included in this content.

Grade 1 ESS Standards

david_schklar — 2015-12-08 15:04:56 UTC

Standard: The physical properties of water can change.

Elaboration:

- Water can be observed in lakes, ponds, streams, wetlands, the ocean and through weather events.

- Water can change the shape of the land (e.g. moving soil or sand along the banks of a river or at the beach).

Grade 4 ESS Standards

david_schklar — 2015-12-08 19:04:21 UTC

Standard: Earth’s surface has specific characteristics and landforms that can be identified.

Elaboration:

- Earth is known as the Blue Planet because about 70 percent of Earth’s surface is covered in water.

- There are many different processes that continually build up or tear down the surface of Earth.

- Beginning to recognize common landforms or features. Common landforms and features include streams, deltas, floodplains, hills, mountains/mountain ranges, valleys, sinkholes, caves, canyons, glacial features, dunes, springs, volcanoes and islands.

- Connecting the processes that must occur to the resulting landform, feature or characteristic should be emphasized.

Standard: The surface of Earth changes due to weathering.

Elaboration:

- The weathering process must be observed in nature, through classroom experimentation or virtually.

Standard: The surface of Earth changes due to erosion and deposition.

Elaboration:

- Erosion is a process that transports rock, soil or sediment to a different location.

- Gravity plays an important role in understanding erosion, especially catastrophic events like mass wasting (e.g., mudslides, avalanches, landslides) or flooding.

- Erosion and deposition directly contribute to landforms and features formation that are included in grade 4.

- Topographic maps and aerial photographs can be used to locate erosional and depositional areas in Ohio.

- Field trips and field investigations (may be virtual) are recommended as erosional and depositional features that can be seen locally or within the state can help to connect the concept of erosion and deposition to the real world.

Ohio Learning Standards - Science

Grade 8 Standards

david_schklar — 2015-12-09 16:42:37 UTC

Standards: Evidence of the dynamic changes of Earth’s surface through time is found in the geologic record.

Elaboration: The representation of the age of the Earth must include a graphic demonstration of the immensity of geologic time, as this is a very difficult concept to grasp.
