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."

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.
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."
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.
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.”
Colony formation on semi-solid medium is basic characteristic of many different bacteria and an important property for microbiologists. These models illustrate the different types of colonies formed, what a colony reflects at the cellular level, how microbiologists obtain isolated colonies, and what happens when cells swarm instead of forming colonies.

Presents the relationships between climates and biomes and climates and people. Also, describes the six major climate types, and shows how weather extremes play a major role in each climate type.
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.
Join host Joel Greene as he explores how batteries can be recycled. The crew visits a battery recycling plant and helps sort the different types of batteries. Part of the Curiosity Quest Series.
Rocks, a naturally formed material that covers the earth, are classified by their origin. Discusses rocks' composition, three types (igneous, sedimentary, and metamorphic), how they are formed, and how they are changed. The rock cycle is a slow, ongoing process.
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.”
Most of the world's insects undergo one of two types of metamorphosis: complete and incomplete. Uses the praying mantis to show an incomplete metamorphosis and the Monarch butterfly as an example of a complete metamorphosis. Includes general characteristics of insects, and gives several examples of both types of changes.
Part of a series that features a wide variety of video footage, photographs, diagrams and colorful, animated graphics and labels. For this particular video, students will focus on the three types of droughts: meteorological, hydrological, and agricultural. Part of the Science Video Vocab Series.
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.
This two-part video introduces the different types of bridges. In part one, simple beam and arch bridges are introduced. The design of each bridge is shown schematically along with the load distribution. The advantages and limitations of each type of bridge is also discussed. Technical concepts covered include tension, compression, bending, span, force balances, material selection, and beam/cable design. Part of "Bridge Design (and Destruction)" series.
