Curated OER
What is the Composition of Soil?
Students examine the different components that make up soil. Using data, they identify the components of soil in their local area and discover how scientists use the soil to see how it was formed. They also describe the soil forming...
Curated OER
What's Happening Below The Surface?
Students determine the soil composition of soil layers in their area. They collect soil samples, calculate the percentage soil water content, analyze data, and evaluate each site for future tree growth.
Curated OER
Water Retention and Soil Variation in Local Ecosystems
Students identify the differences in local soil types and the relationship between soil size and water retention. They are introduced to microenvironmental conditions in ecosystem sustainability.
Curated OER
Optional Laboratory: Soil Particle Size and Texture
Students work together to perform experiments on different types of soil. They record the soil's pH level, color and texture. They develop hypothesis' on what they believe they will discover before beginning the experiment.
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
Sampling the Ocean Floor
Students sample goodies from an unseen ocean floor and try to accurately describe their composition. This simulation helps students explain the limitations of sampling and the problem of obtaining representative samples of sea floor...
Curated OER
"Tri-County" Project--Ground Water
Learners explore data on some of the landforms in Nebraska to distinguish between porous and nonpremeable soils. The state's groundwater is investigated.
Curated OER
"Tri-County" Project--Ogallala Aquifer
Students explore the Ogallala Aquifer in the state of Nebraska. The signs of pollution found are examined and the data classified.
Curated OER
Nature's Recycling Program
Students identify what materials make up compost. In this science of recycling lesson, students explain the benefits of composting determine how compost is a good plant fertilizer.
Curated OER
Seeds of Wetland Life
Students participate in several activities on seed exploration. In this biology lesson plan, students classify seeds according to their dispersal method. They explain the different adaptations plant have to disperse their seeds.
Curated OER
Discovering the Wetlands!
Students name wetland plant and animal life. In this ecosystem lesson students go birdwatching and interpret native plants through art.
Curated OER
Factors Affecting Plant Growth
Students determine the physical and chemical factors that affect plant growth. In this biology lesson, students explain the role of hormones in plants. They investigate how competition with other plants affect their growth.
Curated OER
Sounds of the Wetlands
Students identify the sounds of different bird calls. For this biology lesson, students create a sound map. They explain how this method is important in tracking wildlife.
Curated OER
A Model Aquifer
Students build a model that depicts how water is stored in an aquifer. They examine ways in which groundwater can become contaminated.
Curated OER
Biotic Factors
Students identify individual organism, a species, and a population within the study community. They identify biotic factors at the site and attempt to characterize the site's species diversity.
