Students discover how worms contribute to the balance of the environment. In this composting lesson plan, students study the composting and decomposition processes. Students then create habitats for worms that allow them to do their jobs.

Somehow 55 chemistry problems have been squished onto a single page! Don't assume that it is a mess, however. High school chemists write the products for different types of reactions. Then they identify the type of reaction in addition...

Students explore decomposition and soil health by creating their own garden.  In this agriculture lesson, students build a "lasagna garden" with organic matter found in the area and plant perennials native to their region.  Students are...

The nitrogen cycle is the focus of a well-designed science lesson. In it, learners see that plants and animals produce waste products and decompose after death. Many of the waste products include nitrogen which is absobed by other...

Biochemists experiment with the oxothermic decomposition of hydrogen dioxide by adding manganese dioxide. They observe how pepsin enhances the action of acid on the digestion of egg white proteins. They use yeast to make bread rise. All...

This is not a complete slide show, but rather the general form and a diagram depicting what happens in a decomposition reaction. It is large, colorful, and easy to read. A useful tool for explaining decomposition reactions to your...

This PowerPoint presentation is sure to support your lesson on chemical reactions. Colorful diagrams and pictures, solubility tables and rules, clever animations and diagrams make teaching these concepts a cinch! Your chemistry...

A full-fledged practice final prepares pupils for their general chemistry final exam. If they complete these 57 multiple-choice questions correctly, they will be well-prepared. Note: even though the questions are multiple-choice, there...

Scientists define and discuss decomposition, and watch pumpkins decompose and return to soil in classroom experiment. They record the date the experiment began, chart changes in pumpkins on a calendar, count how many days it takes...

In this chemical reactions learning exercise, students are given the reactants of equations and must complete each equation by writing the products and balancing the equation. They must also identify the type of reaction.

In this reactions worksheet, young scholars complete the given reactions by writing the products. Students do examples of composition, decomposition, single replacement, double replacement, and combustion reactions. This worksheet has 54...

Lower elementary learners recognize solid shapes distributed for making fractions. Each individual uses a wheel and determine which part of a fraction is missing. This is a great lesson for your visual learners!

In this surface area and volume instructional activity, students solve and complete 3 different decomposing rectangular solids. First, they use the given formulas for surface area and volume to calculate the measurements of each of the...

A list of word reactions are given. Your class should write balanced equations, along with giving the reaction type and physical states.

If you are looking for how to introduce elementary environmentalists to the process of composting, here is a comprehensive outline for making it happen. The plan is to set this up at the beginning of a school year in order to observe the...

Students create their own compost.  In this soil lesson, students fill a bag with waste and soil, in order to create a mini compost bin. Students observe the baggies over a 6 week period, they record their findings and collect data on...

A 12-page midterm exam sample can be given to young scientists in preparation for an exam. This particular installment is geared toward a class that delves into both ecology and chemistry concepts. There is no way to separate the 50...

Written for an agriculture curriculum, this presentation on organic matter is also informative for gardening or horticulture classes. It details the chemical makeup, affecting factors, functions, maintenance, and composting to create a...

In these two lessons, science learners participate in various activities involving pumpkins. They investigate and research the life cycle of a pumpkin. They observe pumpkin growth and decomposition. Finally, they estimate and measure...

Now is the time to educate tomorrow's citizens to care for the planet, and here is a lesson to help facilitate the process. Collect some marine debris and bring it into class. Have your class separate it into types and then test each...

Using 2-liter bottles, junior ecologists create composting tubes in which they place nitrogen-rich and carbon-rich materials. They observe what changes occur over two weeks' time. Provide more specific direction to your class as to what...

Ecology explorers or beginning biologists view a time-lapse film of decaying strawberries. They discuss how decomposition occurs and what factors might affect the rate of decay. Alone, the lesson plan is lacking engaging attributes....

Students classify leaves by shape and margins and use them to create models of plant fossils. By using paper over a leaf, they simulate fossilization of organisms onto sedimentary rocks. Following instructions on worksheets, students...

In this isosceles right triangle worksheet, 10th graders solve and complete 5 different constructions of composition and decomposition. First, they make 4 congruent isosceles triangles with the model on the left. Then, students create...
