A Design You’ll Dig: Designing a Habitat for Worms
Students discover how worms contribute to the balance of the environment. In this composting lesson, students study the composting and decomposition processes. Students then create habitats for worms that allow them to do their jobs.

Let's Build a Worm Bin
Students explore the process of decomposition. In this ecology and measurement lesson, students prepare a worm home to be used for vermicomposting. Students weigh a group of worms and the added food, recording this information on a data...

Slow Rot or Not?
Fifth graders examine how environmental factors affect decomposition. In this decomposition activity, 5th graders experiment with the decomposition of grapes in five different environmental settings. They look at images of items that...
SF Environment
Compost Tag
Composting is a great way to get children involved in recycling. First, they discuss how biodegradable products decompose to make compost. Then, they talk about what can and cannot be composted. They play a game similar to around the...

Environment: Banana-in-a-Jar Experiment
Students conduct experiments using bananas sealed in jars to observe the effects on biodegradable waste in landfills. They cover the lid with a plastic sandwich bag to create an airtight seal. Students observe how the oxygen is used...
Curated OER
Dirty Decomposers
Seventh graders design and conduct experiments to determine what environmental factors favor decomposition by soil microbes. They use chunks of carrot for the materials to be decomposed, and their experiments are carried out in plastic...
Curated OER
Rotten Truth
Pupils complete activities to study decomposition. For this decomposition lesson, students work in pairs to observe a decay buffet experiment. Pupils keep compost bag journals. Students define and discuss the process of decomposition.

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...

Forest Floor Terrarium
Students study the aspects of a forest floor ecosystem, including decomposition, the water cycle, food webs, the needs of living things, and physical vs. chemical change over an extended period. In addition, students conduct observations...
Curated OER
Look At A Landfill
Students explore how landfills function. For this landfill lesson, students explore the use of landfills and the decomposition process by creating a model landfill. Students discuss pros and cons to landfills and how potential problems...
Curated OER
Garbage in the Garden
Students create their own compost. In this soil lesson, students fill a bag with waste and soil, in order to create a mini compost bin. Students observe the baggies over a 6 week period, they record their findings and collect data...

Case of the Missing Pumpkin
Students explore the process of decomposition in plants. In this plant biology activity, students use a cleaned out pumpkin and observe how the decomposition process takes place. Students write down adjectives to describe the pumpkin.

Backyard Bacteria
Students experiment with different bacterias that they found and make predictions of their growth. In this investigative activity students use petri dishes to grow their bacteria then summarize what has happened.
Curated OER
The Rotten Truth
Students study the process of decomposition using lunch leftovers and soil. They complete the inquiry over set periods time as they observe the how composting takes place and finally, they sort the materials into biodegradable,...
Curated OER
Compost Cake
Students examine the decomposition process. They create their own class compost pile and record their observations. They discover which materials decompose at a different rate.
Curated OER
Funky Fungus
Students 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 locate...
Curated OER
Microorganisms: Good Guys or Bad Guys?
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...
