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...

Perfectly Decomposed!
We all know someone who won't eat the banana with a brown spot, the grape with a dimple, and the apple with a bruise. Scholars use different fruits to explore what happens when fruits really start to decompose. They set up an experiment...

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.

Soil Composition
Students examine soil. In this soil composition lesson 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.

Interactions of Living Things
Is it a producer, carnivore, omnivore, scavenger, or decomposer? Different relationships among organisms are explored here. It is a simple, multiple choice assignment. Use it as a quick warm-up or quiz.

Cycling of Matter and Energy
These twenty various types of questions related to the cycling of matter and energy require students to match each definition in column 1 with the correct vocabulary term from column 2. Then, students explain what is being demonstrated...

A Symphony of Decomposers
Students discover decomposition. In this environmental lesson, students explore different types of decomposers and their role within the ecosystem. Students 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...
Curated OER
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?
Young scholars 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...
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.

Nutrient Cycling
AP environmental science or college-level ecology classes will glean a tremendous amount of information on nutrient cycles from this detailed PowerPoint. It covers nutrient requirements, biogeochemcial cycles, decomposition rates, and...

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...
Biology Junction
Changes in Ecosystems: Ecological Succession
Can an area with no soil turn into a forest? Scholars learn about the process of ecological succession using an interesting presentation. It covers both primary and secondary succession in the building of new ecosystems.

Kingdom: Fungi
The general characteristics of fungus types are presented here. Your class will love the pictures of the amazing features found on these strange living things. The internal and external structures and their functions are highlighted. By...
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.

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...
