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?
Students 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...

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
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...
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 students perform a composting experiment using flowers in different soils. Students record their observations.
Curated OER
Compost in a Bag!
Fourth graders experiment to see which objects decompose. In 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...
Curated OER
Recycling
Students explore the recycling process. In this recycling lesson plan, students gain understanding of how garbage is disposed of. Students makes lists of things that can be recycled. Students discuss how animals and plants are damaged by...
Curated OER
Identifying and Explaining Reactions
Introduce high schoolers to chemical reactions with this series of activities. In a little over an hour, scientists observe four gas-producing reactions: the combination of hydrochloric acid and sodium hydroxide, placing pasta in...
Curated OER
FBI
Fourth graders experiment with compost. For this Science lesson, 4th graders begin a worm compost as well as an outdoor compost. Students discuss decomposition.
Curated OER
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...
Curated OER
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.
Curated OER
Litter Garden
Young scholars discuss what man-made and natural materials are visible in litter. Using a sample of litter, they review the concept of decomposition between the two types of materials. They examine the two samples once and a while and...
Curated OER
All I Want for Christmas is a Nice, Clean Earth
Students observe properties of items, determine time it takes for organic/inorganic items to decompose, identify differences/similarities between decomposition, identify practical uses in litter/garbage control, & establish reasons...
Curated OER
Investigating Soil
Fourth graders swap local soil samples with another school and examine the differences. They research soil properties, identify organisms that live in soil, create and maintain a biome of soil decomposition and design a poster to present...
Curated OER
Coal Formation
Students create a condition in an aquarium which allows the formation of coal. Students observe changes in decomposition and color of materials present in aquarium before a coal layer appears. Plant "fossil" imprints will be left behind.
Curated OER
Forensic Entomology: What the Blowfly Saw
Students read a paragraph describing various insects and decomposition rates, then fill in the table indicating when the three insects arrived or left the body. They write paragraphs explaining when the person died, and how they know.
Curated OER
H2O2 Decomposition Lab II
Students conduct an oxidation experiment in which they must determine how much hydrogen peroxide (H2O2) is actually in a store-bought solution of H2O2.
Curated OER
COMPOSTING: WHY BOTHER?
Students explore the composting process and participate in a contest to make the most compost the fastest from the school's kitchen and yard waste.
