WORM WATCHING
Students investigate how earthworms help build good soil. They examine the worms carefully to find the ringlike segments and swollen band at the front of the earthworm's body. Students take turns dampening the soil every day and adding...

WHO CARES FOR THE LAND?
Students explore the importance of natural resources. They are given copies of the story, "Who Cares For The Land," and students follow
along as the teacher reads it. Students identify the key points in the story. (Soil, water and air...

Making a Mini Worm Habitat
Third graders create an earthworm habitat. In this worms lesson, 3rd graders construct a KWL chart about earthworms and research their habitat. Students create a mini habitat for their earthworms by using gravel, sand, cloth, and soil.

Making a Mini Worm Habitat
Students explore the process of converting organic waste into usable fertilizer. They observe how living and nonliving things interact with one another by making a mini-worm habitat.
Curated OER
Wonder Underground
Young scholars classify and record objects they find "underground." For this observation lesson, students dig into bins filled with soil and encounter various objects such as bark, twigs, etc. Young scholars classify their findings.
Curated OER
An Underground River
Seventh graders describe how water flows through the ground, what an aquifer is and what soil properties are used to predict groundwater flow. They consider the affects of pollution on groundwater supplies and write a letter drawing...

Observing Earthworm Locomotion
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...

What's Organic?
Learners define and discuss terms organic and synthetic, read article pertaining to organic agricultural practices in Oklahoma, complete worksheet, grow plants using both commercial and organic fertilizer, compare growth rates, and chart...
Curated OER
Erosion
Fifth graders study what erosion is, what causes it, and ways to slow its progress. They complete an experiment that depicts soil moving down a slope as water is poured on it to show how moving water erodes land. Next, they observe...
Curated OER
Erosion
Young scholars discover the meaning of the word erosion and discuss effects of rocks and sticks upon the soil. They then work in small groups to construct a model of erosion to make observations and then write them in their science...

Where is the Dirt? A Lesson in Hydroponics
Young scholars use the Internet to research hydroponic gardening which is the growing of plants without soil. They participate in an experiment where a hydroponic garden is contructed in the classroom for observaion. They recorde...
Curated OER
Composting
Young scholars discover the concept of decomposition. They examine how it makes the soil more fertile and how it helps plants. They put a compost bin in their backyard and record their observations.
Curated OER
Mud in the Water
Sixth graders investigate erosion. In this erosion lesson, 6th graders explore how farming changes the environment. Students construct an erosion model and research ways to protect the soil from excess mud generated by farming.
Curated OER
Root, Root, Root for the Nutrients
Students observe the growth of a seed, predict what will happen when seeds are planted without soil, and conduct an experiment using a hydroponics system.
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.
