Curated OER
Soils
Students apply knowledge of soil, environmental impacts, economics, multiple human demands, and use given data for a proposed scenario in making land use decisions. They debate land use issues and/or scenarios and discuss a case study.

Changing Planet: Permafrost Gas Leak
Pair earth scientists up to use an amazing online arctic portal mapping tool and Google Earth to analyze permafrost changes. They compare changes to data on atmospheric concentrations of methane to see if there is a correlation. Then...
Curated OER
Stream Table
Students explore channelization, riparian habitats and soil erosion to find out about the aquatic habitats in Iowa. In this aquatic habitats lesson, students define important terms and read an article about pollution. Students complete...
Curated OER
Car Wash
Students determine the most appropriate site for a car wash, based on each site's soil characteristics (chemical, physical) and topographic features. They perform an experiment to determine the changes to three different soil types when...
Curated OER
Water-Holding Capacity
Students design and conduct an experiment to compare the water-holding capacity of sand, soil, and moss. They measure the change in weight for each material after adding the same amount of water to each material.
Curated OER
The Effect of Moisture on Soil Temperature
Students analyze the relationship between soil moisture and its effect on soil temperature.
Curated OER
Demonstrating Erosion in Action
Students easure and record volume of water, then measure and record mass of soil. They explain the effects of the following in controlling erosion: Contouring, cover crop, strip cropping, reforestation, inter-seeding.
US Environmental Protection Agency
Carbon Through the Seasons
Meteorologists view an animated video by the Environmental Protection Agency to learn how the carbon cycle works, and then move into groups to analyze and graph actual data of the atmospheric carbon dioxide concentration from Hawaii's...
Curated OER
Tree Identification
Students list four ways to identify trees. In this tree identification instructional activity, students use tree identification techniques such as leafs, bark, wood grain, soil type, and climate to create tables and graphs.
Curated OER
An Investigation into Effects of Rhizobium Soil Bacteria on Nitrogen Availability
Young scholars identify the control and the variables in the experiment. They describe the growth of plants with and without nitrogen fixing bacteria, then name the bacterium responsible for making nitrogen available to the plant.
Curated OER
Excavate and Explore
Students simulate an archeological excavation to explain how archeologists identify, date, and make inferences about their findings. They explain the importance of spatial and stratigraphic contexts in archaeology.
Curated OER
Particulate Matter in the Air
Learners conduct an inquiry exploring the different kinds of particulate matter in the air. They name three different types of particulate matter found in the air and identify different types of solid particulate matter found in the air...
Curated OER
Worms in a Bottle
Students gain a better understanding of the worm and its role in the recycling of organic materials into simpler forms by constructing worm bottles and observing for 60 to 90 days.
Curated OER
Ions in the Environment
Students explain the importance of the five main biogeochemical cycles. In this chemistry lesson, students discuss how ions are transported in the environment. They design an experiment to collect data on eutrophication.
