Curated OER
What's the Matter with My Orange?
Students use oranges to informally explore decomposition, dehydration, fermentation, the water cycle, bacteria, yeast, food webs, the needs of living things, and physical vs. chemical change over a period of three or more months.
Curated OER
Introduction to Worm Bin Project
Students observe the decomposing process of the food chain in a worm bin. They observe whether the type of food fed to worms affect the castings given off during the decomposition process. They learn and practice graphing their findings.
Curated OER
pH Potential
Students experiment to determine the positive and negative impacts of human activities on environmental change. They examine how physical and biological processes such as decomposition affect soil characteristics while looking at the pH...
Curated OER
Uranium On a Diet
Students examine how nuclear reactions differ from other chemical reactions they have studied. They add up atomic masses of both the product and reactant side of an example of uranium decomposition, demonstrating mass loss involved.
Curated OER
Cows, Worms, and Compost
Students study decomposition. In this decomposition lesson, students discuss the background information about decomposition. Students then complete the 'Chew It Twice' worksheet.
Curated OER
Magic Genie
Students observe the chemical change that occurs when sodium iodide is dropped into a flask containing 30% hydrogen peroxide. They discuss how this exothermic reaction occurred as they study the chemical equation involved in the reaction.
Curated OER
Solid Waste and Recycling
In this unit of lessons, students examine solid waste and recycling. They examine the relationship between Native Americans and land. They also decorate bags in which they discover the concept of decomposition.
Curated OER
Selecting Soil Organisms in Compost
Students conduct an experiment to demonstrate that many of the enzyme systems needed to break down society's wastes exist in nature among the decomposers in a compost pile. They culture compost bacteria on starch agar to examine the...
Curated OER
The Akron Global Polymer Academy Lesson Plan Format
Students identify types of garbage that will decompose quickly and the ones that do not. In this decomposing lesson students observe and record the photo degrading of six pack rings.
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
Integrals by Partial Fractions
Students integrate integrals by the method of partial fractions. They then decompose fractions into two or more fractions to make them simpler rational expressions so that they can apply the basic integration formulas. Students also...
Curated OER
Lab: Percent of Composition of KClO3
Students find the percent of oxygen in potassium chlorate. In this percent composition lesson plan, students heat a solution of potassium chlorate using a catalyst, manganese dioxide, to decompose the potassium chlorate and release...
Virginia Department of Education
The Effects of Heat and Acid on the Enzyme Catalase
How quickly do enzymatic reactions occur? Assist the class as they examine heat and pH change to determine the rate of chemical reactions using catalase as an enzyme. Watch them "glow" with excitement!
Curated OER
Organic and Inorganic Waste
Students conduct a scientific investigation about organic or inorganic waste. In this organic or inorganic waste lesson, students create a compost heap to determine the difference between inorganic and organic waste. Students...
American Chemical Society
A Catalyst and the Rate of Reaction
More than 90 percent of chemical products are made using a catalyst. Lesson demonstrates the way a catalyst changes the rate of reaction without altering the chemical reaction. A catalyst doesn't appear as a reactant or a product, yet it...
Curated OER
Partitioning a Hexagon
The task at hand is to partition a hexagon into two, four, and eight congruent figures. Make sure to give your wizards a sheet of triangle grid paper on which to decompose the hexagons. Have them explain which rotations, reflections, or...
Curated OER
Glasses
Provide your class some practice with the dimensions of geometric figures. Here you have a set of three different-shaped, stemmed drinking glasses with diameters and heights provided. Math-minded individuals calculate the volume of each....

Perimeter and Area of Polygonal Regions in the Cartesian Plane
How many sides does that polygon have? Building directly from lesson number eight in this series, learners now find the area and perimeter of any polygon on the coordinate plane. They decompose the polygons into triangles and use Green's...
Curated OER
Lead and Mercury Ion Catalase Inhibition
Students participate in a laboratory investigation in which they observe the effect of temperature and pH on enzyme activity. Students also examine exposure to heavy metal ions and the effect that may have on enzyme activity.
United Nations
Compost Monitor Training
What should go in the trash, and what can be composted? Guide your young conservationists through the process of composing their trash with a lesson about the different ways we can dispose of garbage. Using a trash bag with clean...
West Contra Costa Unified School District
Divisibility Rules Justified
How do you know if a number is divisible? Instructors first prove the divisibility rules for three and four and then class members use this modeling to prove given divisibility rules for eight and nine either individually or in...
Curated OER
Weathering and Erosion
Students examine the similarities and differences between weathering and erosion. They participate in a lab in which they test the effects of different materials when exposed to weathering and erosion. They record their observations.
Curated OER
Conservation in Small Places - Composting
A fabulous lesson introduces the art of composting to your gardeners. In it, youngsters learn about the composting process and how it actually works. They discuss the environmental benefits of composting, and use the "lasagna" method...
Curated OER
Solid Waste
Students determine the percentage increase in output of solid waste in the U.S. They determine the length of time it takes for throw away items to decompose.
