Curated OER
Watershed Works: Unit 1
By constructing a watershed model and identifying watershed features in it, they discover how water erosion changes the landscape. As with most watershed modeling activities, this one is costly in terms of time and materials. It is,...
Curated OER
Science: Draining the Land - the Mississippi River
Students use topographic maps to identify parts of rivers. In addition, they discover gradient and predict changes in the channels caused by variations in water flow. Other activities include sketching a river model with a new channel...
Curated OER
Wetlands/Watershed Model
Students make a model that will demonstrate the flow of surface water across the land in Texas and how materials that originate many miles away can end up in the wetland along the coast.
Curated OER
Wetlands/Watershed Model
Students work together to create a watershed model. They discover the flow of surface water on different topography. They examine how materials originate from miles away and end up in a different wetland.
Curated OER
Creeping
Students observe, measure, and graph a model of slow down slope movement representing soil creep. This task assesses students' abilities to collect, record, and organize data, set up graph axes, plot data points, draw line graphs, apply...
Curated OER
River Planning
Students use a model to conduct an experiment involving dam construction. Based on their observations, they draw conclusions about social, economic, and and environmental issues and make a decision concerning dam location. As a group,...
Curated OER
Probing Under the Surface
Eighth graders use a measuring stick to determine the shape of the inside of the bottom of a box, then apply their knowledge to an additional situation. This task assesses students' abilities to make simple observations, collect and...
