Livestock managers reinforce math and science skills while learning about the nutrients found in manure. They predict which animal produces the largest amount and which animal's manure contains the most nitrogen. Finally, they compare...

Where this is not exactly a lesson plan, it is a terrific outline of how to generate biogas from an animal manure sample. If you are up for the challenge, the generator can be built by your class as a concluding project at the end of an...

It's a gas. Middle schoolers build a biogas generator following the directions in this resource. After a few days of observation, they demonstrate that the gas given off by the decomposing manure is flammable. The activity concludes as...

Eighth graders examine the concept that the sun is the ultimate source of energy for living things. They conduct an experiment in which they roast marshmallows over a flame that has been produced from methane gas, which originates from...

Young scholars reinforce math skills while learning about best practices for protection of water quality in the management of animal feeding operations. They make a table to show results of their calculations and compare and justify...

Students examine how to use ecological analysis to animal production systems.  In this sustainable agriculture lesson students examine where the nutrients flow in a system and complete several activities. 

What is biogas and how is it made? After examining background information about the sources of biogas and biogas generators, class members follow the provided information and build a biogas generator that can be used in the...

Students discuss background information presented by the teacher and read dictionary definitions for the words "organic" and "synthetic." In this gardengin lesson, students complete a worksheet on the material. Students grow and compare...

Young scholars explore how certain foods come to be certified "organic." They write the words "organic" and "synthetic" and given the definitions of each. Students are given dictionaries. They are asked: "What is organic food?" Young...

Explore genetically modified foods through various experiments. In this biology activity, young scholars discuss the safety issues related to GMF's. They conduct a PCR analysis to identify the presence of genetic modification.

Roll up your sleeves and get a little dirty with this elementary and middle school compost lesson. All you need is a large plastic container, a couple old newspapers, some organic waste, and a few hundred worms and you're ready...

Finding a balance between too much protein and not enough doesn't have to be a guessing game. Young scientists use an interactive lesson to learn how to calculate protein content in cattle feed and how to mix feed to create the ideal...

Students 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...

Young scholars 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.

High schoolers name models that are representations of larger objects. They suggest ways that industry, agriculture, and mining affect water quality. Pupils demonstrate the use of lagoons for treating wastewater. Students define the...

Students set up their own composting bin. They observe and record their findings during a period of time. They describe the decomposing process as well.

Students compost in a limited space and describe the decomposing process. Students convert unwanted, organic matter, particularly food scraps and paper into fertile soil.

The Konso are comprised of three groups living in southern Ethiopia; the Garati, the Takadi, and the Turo; that speak three very similar dialects. The Konso are intensive agriculturists, using animal and human manure and terracing to...
