One acre of land can contain more than a million earthworms. Scholars collect earthworms to observe their movements. Once placed on paper, the sound of movement often fascinates pupils. When placed on glass, the earthworm is unable to...

Winter, spring, summer, and fall—take the learning of the seasons beyond the elementary level to the middle school classroom. Curious learners begin by watching videos about the seasons and the rotation of planet Earth. Then,...

Exactly how environmentally friendly is your school? From the air fresheners in the bathrooms to the cleaning solvents used in the classrooms, young conservationists search the school grounds for sources of air pollution in...

From tiny organisms to entire biomes, young scientists examine the interdependent relationships tying all living and non-living things together with this collection of ecology resources.

We all know someone who won't eat the banana with a brown spot, the grape with a dimple, and the apple with a bruise. Scholars use different fruits to explore what happens when fruits really start to decompose. They set up an experiment...

The differences between tropical and temperate rainforests range from animals and flowers to climate and landscapes. Kindergarteners compare and contrast characteristics of their local forest to a tropical rainforest.

Students study four types of soil and predict which one worms would use for their habitat. They observe worms in each type of soil and monitor their activity. They create class charts highlighting their discoveries.

Students analyze the relationship between soil moisture and its effect on soil temperature.

Fourth graders review how erosion can happen by wind, water, and gravity which they studied in previous lesson. They attempt to discover if all soils erode at the same rate. In small groups, 4th graders experiment with three different...

Students 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.

Students examine the distribution of geology, soils, groundwater, topography, and geography in Nebraska. They identify various regions and characteristics on a map, and develop a plan to manage the soil and groundwater resources of the...

Students generate four statements and four questions based on their current level of understanding of the article from the engage activity. They evaluate the statements and questions that they have generated and those of their...

Students examine rocks and minerals. Using the internet, students research rocks and how they are formed. They use word processing software to list minerals and materials that form specific rocks.

Pupils are able to identify questions they need to answer to comprehend a specific news article. They are pushed to question how they know that their drinking water is safe.

Student explore ecosystems. In this ecosystem organization lesson, students consider how scientists study living organisms. Students participate in a teacher guided activity that requires them to visualize an organism and imagine its...

Young scholars explore the scientific reasons that certain types of foods cause different reactions when they interact with the tongue. They analyze the differences between acids and basics. The experiment is performed at three different...

Students examine soil. In this science lesson, students examine the layers of soil. Students collect soil from various locations and separate the layers. Students record and chart their findings.

Students test and identify soil and rock samples. For this rock and soil lesson, students video themselves gathering samples. Students test the samples and create graphs showing the results.

Fourth graders investigate compost. In this Science lesson, 4th graders take notes on the components of soil and its relation to plant growth. Students describe the steps in making compost.

Young scholars discover the importance of plant and animal components within soil. In this soil lesson, students test the quality of soil. Young scholars then conduct an experiment adding different components to bags of soil to see what...

Fourth graders explore different levels of soil. In this soil lesson, 4th graders investigate the amount water that can be absorbed by topsoil, subsoil, and bedrock.

Fourth graders explore different types of land. In this land lesson, 4th graders investigate how water, climate, and soil type determine what types of crops may be grown. Students discover these elements while playing an interactive game.

Fourth graders examine earthworms. In this earthworm lesson, 4th graders investigate how earthworms help prepare soil for planting. Students examine other living and nonliving elements in a garden habitat.

Students conduct a laboratory experiment designed to investigate the effects of chemicals, soil quality and pollution on seed growth and plant yield. They consider how best to maximize agriculture in the long term.
