Curated OER
Chemical Reactions
In this chemical reactions instructional activity, students determine the half-life of a chemical compound for a decomposition reaction. Students determine the activation energy for the reverse of a reaction. This instructional activity...
Curated OER
Integrals by Partial Fractions
Young scholars 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...
Curated OER
"Boy Meets Chemistry... and has a Reaction!"
Students identify the four main types of reactions: synthesis, decomposition, single replacement, and double replacement. They explore the four main types of chemical reactions through an analogy of "Boy Meets Girl" and then "act out"...
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
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
Coal Formation
Pupils 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
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
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
Deconstructing, Decomposition and Compost
Pupils create and tend to an outdoor compost pile. They research about decomposition and composting. They create two activities for their peers to complete.
Curated OER
Decomposition
Students are introduced to the concept of decomposition. They examine decomposition in their school orchard. They write about their findings in a journal.
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
Watching Waste Rot
Students investigate what types of materials decompose, and at what speeds.
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
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.
