Students explore what problems might occur if oxygen decreases in a body of water. They model what happens in a situation where decomposition is occurring. Students obtain, organize, graph, and interpret information. They i interpret...
Curated OER
Forest Floor Terrarium
Young scholars 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...
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...

Organic Matter
Written for an agriculture curriculum, this presentation on organic matter is also informative for gardening or horticulture classes. It details the chemical makeup, affecting factors, functions, maintenance, and composting to create a...
Curated OER
Decomposition vs. Synthesis Reaction
Young scholars define the term chemical reaction, identify the reactants and products in a chemical reaction, distinguish between decomposition and synthesis reactions and construct reactions using food items.
Curated OER
Look At A Landfill
Students explore how landfills function. In 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
Case of the Missing Pumpkin
Students explore the process of decomposition in plants. In this plant biology lesson, students use a cleaned out pumpkin and observe how the decomposition process takes place. Students write down adjectives to describe the pumpkin.
Curated OER
Composting
Using 2-liter bottles, junior ecologists create composting tubes in which they place nitrogen-rich and carbon-rich materials. They observe what changes occur over two weeks' time. Provide more specific direction to your class as to what...
Curated OER
Where Does Al the Waste Go?
Young scholars construct a sanitary mini-landfill and an open mini-dump. Over a thirty day period, they compare the two methods and determine landfills are envorinmentally safer. They observe a demonstration of burning waste. They create...
Curated OER
Science: Fossil of a Carbonized Plant
Students classify leaves by shape and margins and use them to create models of plant fossils. By using paper over a leaf, they simulate fossilization of organisms onto sedimentary rocks. Following instructions on worksheets, students...
Curated OER
Sample Midyear Examination (Chemistry and Biology)
A 12-page midterm exam sample can be given to young scientists in preparation for an exam. This particular installment is geared toward a class that delves into both ecology and chemistry concepts. There is no way to separate the 50...
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 on...
Curated OER
H2O2 Decomposition Lab I
Students conduct an experiment to determine how much hydrogen peroxide (H2O2) is actually in a store-bought solution of H2O2.
Curated OER
Now You See It, Now You Don't
Students explore organic and inorganic objects. In this environmental lesson plan students perform a composting experiment using flowers in different soils. Students record their observations.

Predicting the Products of a Reaction
In this reactions instructional activity, students predict the products of 5 equations and write the equations for 5 reactions using their knowledge of types of reactions.
Curated OER
Compost in a Bag!
Fourth graders experiment to see which objects decompose. For this compost lesson, 4th graders observe the changes of labeled objects in a bag. Leave the objects for one month and record the changes by observation and weight. Students...
Curated OER
"Leaf" It in Your Yard
Students research about the process of composting. Students apply their research by creating a compost pile at school that will be maintained once or twice a month for the remainder of the school year.
Curated OER
Composting Conundrum
Learners research cafeteria composting. In this composting lesson, students design a vessel that would allow the cafeteria staff to collect food scraps for composting. Then learners build a prototype and present it to the class. Lastly...
