Students are introduces to soil profile classification. They remember that classification of soils is an important aspect of studying soils as it aids in predicting how soils react to weathering, transport nutrients or pollution. ...

Students are introduced to the differences that exist in soil properties with depth. They are introduced to the factors that influence a soil's development (soil forming factors). Pupils are introduced to the impact of soil of soil...

Third graders explore the process of composting. In this composting instructional activity, 3rd graders read the book Wonderful Worms, and create composters.

Students conduct a series of experiments on mulching. In this earth science lesson, students discuss the benefits of mulching on soil. They explore how different types of mulch affect plant growth.

Students investigate the Earth's crust. In this geology lesson, students identify the materials made up of the Earth's crust and investigate the different kinds of soil.

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. ...

Learners design an experiment to test the effects of common fertilizers on grass growth. They write or present a laboratory report responding to their observations and consider how fertilizers may affect the soil environment.

Students explore the needs of plants.  For this plants biology lesson, students work in groups to perform an experiment with tomato plants.  Each group records observations in a journal, takes pictures, and interprets the...

Students investigate how organic matter increases the amount of water soil will hold. In this water soil lesson plan, students use soil and measure water amounts using organic matter. Students measure the water holding capacities.

Students examine the changes in Earth's temperature. In this global warming lesson, students perform an experiment testing temperatures of soil. Students record their findings and discuss what made the differences in the soil temperature.

In this porosity and permeability instructional activity, students experiment with different types of soils such as sand, gravel, pebbled and rocks. They put each soil type in a beaker and pour water in being sure to measure the amount...

Students research the effects of soil erosion and pollution in the soil.

Students plant wetland plants in aquatic soil and regular soil. They test the effect fertilizers have on each and record the chemicals found in run-off water collected from each soil sample.

Young scholars gain knowledge about the impact of drought in agriculture. They investigate soil types, water flow, and various erosion conditions which occur during a drought and see how farming practices changed after the 1930's.

Fifth graders simulate wind driven soil erosion by using paper confetti to demonstrate the movement of the soil. They write about three examples of soil erosion found in their community.

Students create a compost cake. In this gardening and decomposition science activity, students review and describe the "nutrient cycle." Students create a compost pile, measure and record the dimensions and temperature of the pile, and...

Students research about the physiological effects of prolonged lead exposure. In this chemistry lesson, students investigate the lead content of different paint, soil and water samples. They analyze data trends and share their findings...

Students investigate the composting process through a variety of experiments. In this ecology lesson, students discuss the benefits of composting. They examine how compost affect plant growth.

Fifth graders compare and evaluate the rate of erosion from water and wind on three type of landscape: bare land, land with sparse vegetation, and land covered by dense vegetation.

Students collect data as they identify and classify native prairie plants and insects. They create their own population study using a variety of sampling techniques to determine the population density of various species. Students...

First graders investigate composting. In this biology lesson, 1st graders identify ways to use garbage as fertilizer. Students examine soil and compost matter as well as the role of worms in the dirt.

Third graders explore agriculture by viewing a PowerPoint presentation in class. In this animal relationship lesson, 3rd graders identify the types of farm animals humans feed on and their dependency on such small insects like worms....

For this environmental lesson students complete a series of multiple choice and short answer questions on animal populations, cell structure and chromosomes.

Seventh graders examine the different types of pollutants. In this environmental science lesson, 7th graders observe particulate matter under a microscope. They explain how these can affect once health when breathed in large quantities...
