Students investigated how wind erodes sand and sediment by simulating a windstorm.
Homework- Wind Erosion Reading and questions due Wed. Students finished the glacier activity by observing how the sediment deposited after the "glacier" melted. We observed glacial striations and morraines.
No homework Fourth graders learned about glaciers and discovered how glaciers work to erode land. We used a frozen water and sediment mixture to simulate a glacier and we moved the glaciers over clay to simulate how glaciers erode the land.
No homework Fourth graders learned about weathering and abrasion by rubbing rocks together and observing the amount and size of sediment that came off the rocks. We also began an investigation by putting two rocks in jars with water and shaking them, simulating rocks in a river.
Homework- It happens when it rains reading and questions due Wed. Fourth grade students finished discussing their stream table experiments and we also began talking about erosion and deposition.
No homework Fourth graders used their stream tables again to investigate how certain variables can affect the erosion of a river. They chose to alter the slope of their stream table or adding buildings to their land area. Ask them what happened.
No homework Today in science, students used their stream tables again and observed the water carving the land. We learned that when the water moves sediment, it is called erosion. We also learned the parts of a river.
Homework- Landforms reading due Wed. On Wednesday, we looked at pictures of landforms and talked about what those landforms are called and how we predicted they were formed.
On Friday, we used stream tables and sand to simulate a river. We observed the sand moving with the water. Today in science, students earned a free day. They chose to watch a Bill Nye video about Rivers and Streams. Homework- Intro to Landforms packet due Wed.
