Many of the things we eat and enjoy are grown in soil. This program explores the various types of soil and rocks. The narrator also describes the different characteristics of soil and rocks. Viewers also learn the importance of soil while taking a look at how soil is formed.

In this video, students will learn about the two major types of weathering: mechanical and chemical. These forces alter the shape and composition of rocks. Students will also explore the different types of soils, soil properties, and soil profiles. Other topics covered include oxidation, soil formation, soil texture, horizons, leaching, subsoil, soil conservation, and groundwater.
Surveys soil's formation, composition, properties, types, and movement. Also identifies the five major plant communities: tundra, forests, scrublands, grasslands, and deserts. The connection between soils and vegetation affects where people live.
Part of a series that features a wide variety of video footage, photographs, diagrams and colorful, animated graphics and labels. Begins with a simple definition of the term and concludes with a critical thinking question. For this particular video, students will focus on the term soil. Part of the Science Video Vocab Series.
Nourish is an educational initiative designed to open a meaningful conversation about food and sustainability, particularly in schools and communities. In this clip, author Michael Pollan explains the need for healthy soil. Part of the Nourish Short Films Series.
Host Peter Tonge visits with Paul Rogers of Stonehedge Nursery who offers tips on growing culinary herbs from seeds indoors on a windowsill. Also shows how to identify soil type with a basic 10-minute test. Looks at some of the organic additives you can use to improve your soil. Originally aired as an episode of "The Good Green Earth."
Since the last ice age, plants in the Alaskan Arctic have been taking carbon out of the atmosphere and locking it away in the soil. But now, the permafrost is starting to thaw. That means all those microbes are about to find themselves at an all-you-can-eat carbon buffet. With support from the National Science Foundation, ecologist Matthew Wallenstein and a team from Colorado State University have come to the Toolik Field Station, deep inside the Arctic Circle, to drill soil cores for study. The researchers are trying to find out more about how microbes in the soil are cycling carbon from the Earth to the atmosphere. Part of the National Science Foundation Series “Science Nation.”
Host Peter Tonge visits with Robert Almquist of Almquist Flowerland who offers tips on raising and caring for houseplants. Covers the following topics: watering during winter months; combating pests; buying houseplants; repotting and pruning; determining types of soil; and using a granular soil additive to help the soil retain moisture. Originally aired as an episode of "The Good Green Earth."
Climb aboard the Cyclops, a microscopic research vessel, and investigate an amazing hidden world on which all living things depend. The Cyclops houses a team of scientists known as the Micronauts and guides them through their discoveries of biological classification, diversity, and ecology. In this episode, the Micronauts come face to face with earthworms. While exploring their burrows, the crew observes the anatomy of earthworms and develops theories about the role earthworms plays in maintaining terrestrial ecosystems. Part 12 of Microscopic Monsters Series.
Preserving the environment and developing agricultural products that do not harm unintended targets are top priorities for many scientists and farmers. It’s a new era of crop management known as precision agriculture. It maximizes productivity while minimizing energy use and environmental impacts. One of the major challenges being addressed by precision agriculture is over-fertilization. Support from the National Science Foundation (NSF) has led to the development by startup SupraSensor Technologies of a novel sensor to detect nitrate fertilizer in soil. The SupraSensor device is designed to give farmers a highly accurate, virtually constant stream of data on nitrate levels. Part of the National Science Foundation Series “Science Nation.”
Think of earthworms and a few things come to mind: they make great bait for fishing, they aerate the soil, and they’re an excellent addition to a compost pile. But, what a lot of people don’t know is many earthworms are actually invasive species. Earthworms may be small but when they take over a forest, the impact is dramatic. They cause the rapid incorporation of organic material into the soil, changing its structure, chemistry and nutrient dynamics. What's known as the duff layer is suddenly removed, and this duff, or decaying organic material on the forest floor, is habitat for several species of insects, spiders, small vertebrates, bacteria and fungi. It is also the primary rooting zone for most plants.
How does organic farming differ from other methods? A team explores soil conditions, water availability, climate, and different techniques.
Shows how gravity affects erosion. Documents how scientists study erosion and weathering. Highlights the California landslide problem. Surveys the destruction caused by fast erosion. Explains why deforestation and building houses and other structures contribute to erosion.
Investigates rivers and their impact on land. Shows how rivers and streams are formed, and how they carve channels into soil and rock. Discusses stream classifications, the fluvial process, the effect of gradient, and how waterfalls are formed. Preview of vocabulary recommended.
The importance of forests cannot be underestimated. Humans depend on forests for survival, from the air they breathe to the wood they use. Besides providing habitats for animals and livelihoods for humans, forests also offer watershed protection, prevent soil erosion, and mitigate climate change.
In this segment, students learn about the process of weathering. It is the breaking down of rocks, soil, and minerals through contact with the earth's atmosphere, water, and biological organisms. Other topics covered include erosion, surface water, groundwater, wind, and waves. Part of the "Earth Science" series.
What is the largest living thing on earth? What are the four levels of a forest? Bill Nye explores a forest, its purpose, and its by-products. Visit different kinds of forests, a timberline, and a forest fire.
Alibates Flint Quarries show the intersection of climate and geography, and its impact on Texan history and culture. For thousands of years, Native Americans came to the red bluffs above the Canadian River for flint. They used Alibates flint for spear points to hunt and had to dig it by hand.
Provides step-by-step instructions on how to grow a variety of plants in containers. Includes the following topics: varieties of containers (available for purchase); how to make your own container; container selection and preparation; soil preparation; choosing plant varieties; bringing it all together: examples of assembled containers; and care and maintenance of plants.
