Students identify what materials make up compost. In this science of recycling lesson plan, students explain the benefits of composting determine how compost is a good plant fertilizer.

Young scholars discuss decomposition, bacteria, fungi and other microscopic organisms. They participate in an experiment to grow fungus on bread. As the fungus colonies grow, students observe them under a microscope to identify and...

Students discover the role microorganisms play in our lives. In this decomposition lesson, students examine decaying foods and plants in order to analyze the different bacteria that grows. Students discuss the good and bad of...

Students explore Green Construction. For this lesson based on the experiences of Peace Corps volunteers, students gain insight into alternative construction in Guatemala. They examine the pros and cons of using alternative building...

Students conduct a series of experiments on mulching. In this earth science lesson, students discuss the benefits of mulching on soil. They explore how different types of mulch affect plant growth.

In this recycling and waste disposal worksheet, learners check one of 5 boxes with predictions on how long certain materials such as styrofoam and glass take to decompose and disappear underground. There are 10 items that students must...

Students take charge of a recycling project . In this environmental issues lesson, students manage a paper recycling project and use compost made from the recycled paper to beautify trees.

Pupils conduct an experiment in which they bury four objects (apple, lettuce, plastic and styrofoam) in the ground and come back to observe them a month later. They consider what biodegrades and how it affects our planet.

Students identify insects living in rotting logs. In this decomposition lesson, students observe pieces of a rotting log, they look at the insects that have inhabited the log and create a chart that shows their findings.

Young scholars discover the concept of decomposition. They examine how it makes the soil more fertile and how it helps plants. They put a compost bin in their backyard and record their observations.

Students observe the decomposing process of the food chain in a worm bin. They observe whether the type of food fed to worms affect the castings given off during the decomposition process. They learn and practice graphing their findings.

For this unit of lessons, students examine solid waste and recycling. They examine the relationship between Native Americans and land. They also decorate bags in which they discover the concept of decomposition.

For this unit of lessons, students examine the role of compost columns and recycling. They create a KWL chart about garbage in Chicago. They also examine life cycles and packaging of everyday products.

Students conduct a scientific investigation about organic or inorganic waste.  In this organic or inorganic waste instructional activity, students create a compost heap to determine the difference between inorganic and organic...

Students read about the bags that the Maya people made and about how reusing bags can help save our environment. In this environment lesson plan, students read and discuss conservation and observe pictures.

Students examine how not all microorganisms are bad and that some can actually be beneficial.  In this yeast instructional activity students complete an experiment with yeast and answer questions.

Students explore Le Chatelier's Principle. In this lesson about chemical equilibrium, students do an experiment with several different activities . Students observe as they do the experiments and understand the outcome. Students become...

Students observe a composting box. For this soil lesson, students create a composting bin by using a bin, newspaper, worms, and food scraps. Students create a composting food web.

Second graders examine compost piles and what invertebrates help decompose the organic matter.  In this compost invertebrates lesson students collect invertebrates found in a compost pile and examine them. 

Students work together to collect soil samples from different locations. In the samples, they identify the macroorganisms and classify them. They identify the conditions that affect how macroorganisms grow. They also analyze and identify...

A lab where students construct Decomposition Columns from two-liter plastic bottles, and then observe them over a period of time.

Students conduct experiments to determine what environmental factors favor decomposition by soil microbes. They use chunks of carrots for the materials to be decomposed, and their experiments are carried out in plastic bags filled with...

Students design and conduct experiments to determine what environmental factors favor decomposition by soil microbes. They use chunks of carrots for the materials to be decomposed, and their experiments are carried out in plastic bags...
