Soil Decomposers
The class studies the soil food web that includes earthworms and conduct four experiments using the crawly critters. Individuals determine whether earthworms are sensitive to light, touch, temperature, and acid.

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...

Helping the Soil
In this soil conservation worksheet, students study and analyze two excellent ways to enhance soil conservation: compost heap and leaf-mould. Students review all the ingredients in making both.

Recyclers Revisited
Fifth graders observe their plant experiments that they started in a previous lesson and examine the role of decomposers in the nitrogen cycle. Two weeks after they set up a worm terrarium, they analyze any changes they observe, and...

Climate and Temperature
Students explore what the soil temperature would be on the north and south sides of a building. In this temperature lesson, students hypothesize what the results will be using a thermometer and then after a week see what the temperatures...

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....

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...

Composting: Why Bother?
The first STEM lesson in a group of 10 explores composting. After discussing how to make a better tomorrow, classes are challenged to track garbage in their communities, visit a local waste management facility, and conduct a survey about...

Soak It Up
Young scholars examine the various materials that make up their local soils. In groups, they record how each material is different and use cheesecloth to filter them into a bottle based on particle size. They use the soils to determine...

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...

Worm Composting: Vermiculture
Students compost in a limited space and describe the decomposing process. Students convert unwanted, organic matter, particularly food scraps and paper into fertile soil.

Back to the Earth
Students 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.

Worm Composting: Vermiculture
Students set up their own composting bin. They observe and record their findings during a period of time. They describe the decomposing process as well.

Life in a Log
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.

Making a Mini-Landfill
Students create a mini-version of a landfill. They examine the materials they use everyday and determine if they decompose or not. They identify the materials as renewable or nonrenewable as well.

Discovering Local Food Chains
Fourth graders study about food chains. With the assistance of a local biologist, Students hike the school trail system. They explore ecosystem and collect data by charting the organisms found and identifying the energy source. They...

The Effects of Trash and Garbage On the Environment
Students recognize the importance of solid waste management. In this science lesson plan, students analyze individual solid waste management habits as they enhance their knowledge of solid waste disposal and the recycling process.
