Curated OER
Agents of Erosion
Fourth graders observe and identify the effects of geological activities and weathering on Earth's surface. They also take a look at reports of events such as storms, earthquakes, floods, and volcanoes. There is a hefty hands-on activity...
Curated OER
Weathering and Erosion
Students examine the similarities and differences between weathering and erosion. They participate in a lab in which they test the effects of different materials when exposed to weathering and erosion. They record their observations.
Curated OER
Rocks, Minerals, and Erosion
Students identify and describe rocks that contain records of the earth's history and explain how they were formed. They formulate questions about and identify needs and problems related to objects and events in the environment, and...
Curated OER
Agents of Erosion
Fourth graders explore the agents of erosion. They observe rocks that are rough and unweathered and record observations. They investigate rocks rubbed with sandpaper and ones that are not and the effects that the sandpaper has on the...
Discovery Education
Weathering Cubes
Weathering is not necessarily a result of the weather. Scholars conduct an experiment to explore the effect of surface area and volume on the weathering process. They create their own sugar cube rocks using the same number of cubes—but...
Curated OER
Water Pollution Experiments
Fifth graders conduct experiments in simulated water pollution using a box of items to hold "pollutants"and an aquarium, representing a waterway. They observe how "rain" from a watering can poured into the box washes the pollutants into...
Curated OER
Seas of Grass
Students view a video clip about grasslands. They identify threats to grasslands and describe cultures which have adapted to grassland conditions. They discuss possible solutions to preserve grasslands as well.
Curated OER
Ocean Life
Students explore the topics of ocean water salinity, ocean life zones, marine life classification, and ocean food chains. They observe demonstrations, conduct experiments, complete quizzes and handouts, and analyze key vocabulary.
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.
Curated OER
Pollution Solution
Fourth graders examine how trees help to absorb the pollution that is emitted from automobiles. They review the process of photosynthesis and determine how forest management is important on their reservation. They think about the...
Curated OER
What If the Reef Dies?
Students complete four activities to investigate how reef ecology can change. They perform experiments to show how sewage discharge can affect a marine ecosystem, look at substances that don't dissolve in water, examine wave action...
Curated OER
THE TRICKLE DOWN EFFECT
Students participate in an exercise which demonstrates how sediments are deposited.
