Soil Decomposers
Worms are the kings of the decomposers. A four-part lesson has learners experiment with the characteristics of earthworms and their sensitivities. They vary factors such as light, acidity, temperature, and touch of soil and observe the...

Soil Stories
Tenth graders collect and analyze soil samples and extrapolate the characteristics needed to support different types of plant life. They research different types of prairie soil and how it supports plant and animal life.
Curated OER
Soil Composition
Students examine soil. In this soil composition activity students participate in soil sedimentation and filtration activities. The students discuss what non-living and living things are in soil and why it is so important.

A Symphony of Decomposers
Young scholars discover decomposition. In this environmental lesson, students explore different types of decomposers and their role within the ecosystem. Young scholars also discover how waste interferes with the decomposition process.

COMPARE SOILS BY GROWING PLANTS
The student will identify the difference in the rate of plant growth in three soils that vary in organic matter.1. Obtain three to four flowerpots, different types of soil, a record chart, three to five beans for each pot, and water....

Compost Lesson
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...

Mini-Ponds
In this mini pond worksheet, students create a mini-pond ecosystem with soil, water, and plant life. Students let their ecosystem sit for a day and they observe a sample the next day. Students identify all the pond water microorganisms...

Selecting Soil Organisms in Compost
Students conduct an experiment to demonstrate that many of the enzyme systems needed to break down society's wastes exist in nature among the decomposers in a compost pile. They culture compost bacteria on starch agar to examine the...

TE Activity: How Fast Can a Carrot Rot?
Students experiment to define which environmental factors favor decomposition by soil microbes. They decompose carrots in dirt, weigh the carrots periodically to determine how long it takes. They look at how engineers use this type of...
Curated OER
The Nitrogen Cycle
Students design and create a compost pile in order to study the Nitrogen Cycle. They then use the scientific method to determine if plants grow better when they add organic matter from their compost pile to the plant's soil.
Curated OER
Dirt Life
Students select and collect soil samples from a variety of locations (schoolyard, home, etc.). They do this lab after an interest-generating discussion about "dirt" and microbes. Students make a dilution in sterile water, plate it on a...
Curated OER
Build an Indoor Compost Bin
Students write an essay to describe the contents of a compost bin. In this composting lesson, students create a compost bin. Students examine soil for its contents and explains in an essay the impact of the soil on the environment.

Worms! Nature's Recyclers
Third graders explore the process of composting. In this composting lesson, 3rd graders read the book Wonderful Worms, and create composters.

Composting: A Scientific Investigation: California Academy of Sciences
Garbage, recycle, compost: Does it really matter where we put our trash once we are done? By making detailed observations over seven weeks, kids will see which materials break down naturally to become a healthy part of the soil, and...
Curated OER
Selecting Soil Organisms in Compost
Students demonstrate that many of the enzyme systems needed to break down--and therefore clean up-society's wastes already exist in nature among the decomposers. They select the best starch-munching organisms by altering the environment...
Curated OER
RIDE THE WILD LEAF
Students identify and interpret that leaves provide food for new trees and plants. Students cut out leaves and glue them on the appropriate
number on included worksheet. Students collect different types of leaves and make leaf rubbings....

Decomposers at Work!
Students design and conduct investigations that illustrate the process of decomposition. After a lecture/demo, students simulate the process of soil composting in the classroom. They closely chart the decomposition of their soil.
Curated OER
Decomposing Artifacts
Seventh graders participate in an experiment in which they calculate the time of decomposition of different materials. In groups, they fill bags with different materials and cover them in soil. After six months, they create a line graph...

Composting "The Right Mix"
Students investigate the correct mix of material types for compost. In this composting lesson, students explore the correct amounts of different types of materials to create a compost heap. Students then create a compost heap.

Living & Non-Living Interactions
What better way to learn about ecosystems than by getting outside and observing them first hand? Accompanying a field trip to a local park or outdoor space, this series of collaborative activities engages children in learning about the...
Curated OER
A MINI LANDFILL
Students observe the difference between degradable and non-degradable wastes. They create their own landfill in a jar by adding four or five pieces of garbage and then covering it with dirt and water. They make observations on what they...
Curated OER
Classroom Composting
Pupils discover the benefits of composting. They identify the steps of decomposition as well. They are read a book and discuss what items decompose.
Curated OER
Can Fun Gus Help Plants/Trees Grow?
Students participate in an experiment in which they test the growth of different types of plants. They discover how growth rates vary using inoculum. They draw pictures and are read books about plants to end the lesson.
Curated OER
Investigating the Uses of Backyard Bacteria
Students discover that the answers to some of society's waste and clean-up problems may be no further than the soil beneath their feet. They perform a Gram stain on the colonies to determine some of their characteristics.
