A step-by-step discussion of the stages in the carbon cycle. Each step includes a diagram further explaining the processes involved, as well as pictures depicting combustion, respiration, photosynthesis, and decomposition.

In this experiment, students investigate what impact the composition of soil, its water content, and its location have on the soil's temperature, which in turn would have an effect on the rate of decomposition of organic matter in the soil.

This lesson focuses on Electrolysis, the decomposition of a liquid using electricity. When ionic compounds are molten or dissolved in water the ions are free to move. It offers links to a video and a test.

Very thorough description of different organisms involved in decomposing organic material through composting. Includes actinomycetes, bacteria, fungi, and a variety of macro-organisms which also function as decomposers. Also discusses...

This task is a straightforward task related to adding fractions with the same denominator. The main purpose is to emphasize that there are many ways to decompose a fraction as a sum of fractions, similar to decompositions of whole...

Young scholars explore the relationship between addition and subtraction and develop an understanding of decomposing numbers in different ways in this first-grade lesson plan.

This resource offers a detailed overview of the taiga biome, including its locations, the types of plants and animals that live there, and other interesting facts.

In this lesson students conduct a soil analysis to understand soil types and explore the relationship between the garden and healthy, fertile soil. Soil is a natural resource that is crucial to life on Earth and when managed properly, it...

Throughout the world, death and the rituals that surround it are steeped in taboos. Explores what happens to us when we die and the different ways we deal with death.

In a multi-week experiment, students monitor the core temperatures of two compost piles, one control and one tended, to see how air and water affect microbial activity.

Comprehensive description of the environmental benefits of composting solid waste. Complete directions for composting, detailed description of composting chemistry, suggestions for applications of humus, question and answer page,...

By studying key processes in the carbon cycle, such as photosynthesis, composting, and anaerobic digestion, students learn how nature and engineers biorecycle carbon.

Nearly one third of our food ends up in the trash can. Matthew Ross details the steps we can all take to vermicompost at home, and why it makes good business sense to do so. [4:29]

PBS KIDS Lab is built on the belief that every new technology is a learning opportunity. This page includes links to PBS programming, apps, games, videos, activities, and education resources. Teaching Tips provide step-by-step lessons...

What is prime factorization? This site goes through a step-by step process explaining different ways to find the prime factorization.

A brief discussion of orthogonal polynomials that gives a couple of examples.

Learn how composting works, how to build a composter, and a recipe for creating your own compost to fertilize your garden and crops.

Dozens of statistical terms are defined and illustrated in this glossary.

After learning about and reviewing the types of chemical equations and rules for balancing, students can practice balancing equations on interactive quizzes.

[Free Registration/Login may be required to access all resource tools.] Express a vector as two component vectors.

Students will learn how to determine the product by decomposing the factors.

Math Forum offers a description of remainder and factor theorem and gives and example of their uses.

This resource from the Texas A&M University is easy to understand and contains everything you need to know about composting. The basic lessons are supplemented with pictures of students involved in setting up compost bins and trenches.
