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

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...

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...
Curated OER
Soak It Up
Students 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 if...

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
Learners compost in a limited space and describe the decomposing process. Students convert unwanted, organic matter, particularly food scraps and paper into fertile soil.
Curated OER
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.
Curated OER
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.
Curated OER
Life in a Log
Learners 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.

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.
