Curated OER
Erosion: Natural or Unnatural
Students explore how water has the power to erode, how developing the land (building roads, buildings and parking lots) increases the amount of water reaching our rivers, and how this greater quantity of water increases erosion. They...
Curated OER
Water Speed and Erosion
Fourth graders investigate the process of water erosion. They observe the roots of a plant and discuss the concept of erosion. Next, in small groups they conduct an experiment to observe how water erodes soil on a stream table, and...
Curated OER
Erosion Lab
Eighth graders explore variables that influence the rate of erosion due to the 4 major agents. They work as a group and practice conducting experiments according to the scientific method. Students comprehend that communicating ideas...
Curated OER
Stream Table
Students build and erode a hillside. In this earth science activity, students build a five inch hillside in a paint pan using sand, soil, and pebbles. They pour water over the hillside to monitor the erosion and how it is affected by the...
Curated OER
Water: Naturally Cleaned
Young scholars use stream trays covered in different types of rocks or soil to investigate infiltrates and runoff. For this water pollution lesson, students work in groups with stream trays that have different substrates. They write a...
Curated OER
Soil and Agriculture:Lesson 3 - Soil Erosion
Middle schoolers reseach the different types of soil erosion and ways to control it in this series of activities.
Curated OER
Geography Action! Rivers 2001- Stream Table
Students use a stream table to simulate river and watershed systems. The affect of gradient on stream flow as well as erosion and deposition are two items that students examine.
Curated OER
Beach Erosion Investigation
Students determine the effects of gentle and strong waves on beach erosion. They use a stream table to simulate a beach and sketch the beach profile after simulated waves of different sizes.
Curated OER
Barrier Islands
Third graders explore how barrier islands work. In this erosion lesson, 3rd graders create barrier islands in stream tables and simulate wave action to see how it affects their island.
Curated OER
Sediment Tubes
Young scholars observe how different density soils and rocks behave in wind and in water. They make predictions and careful observations as they explore sediment transport and sediment rates in streams and rivers.
