### We found 148 resources with the concept decomposition

Lesson Planet: Curated OER

#### Energy Resources Scavenger Hunt

In this environment learning exercise, students complete each of the statements with its correct energy resource. They identify and name various types of plants and rocks. Students also identify and explain how fertilizer works and how...

Lesson Planet: Curated OER

#### Fossil Fuel Scavenger Hunt

In this earth science worksheet, students complete each of the statements with the correct fossil fuel. They identify when and where electricity first became available. Students also define fossil fuels and where they first got their...

Lesson Planet: Curated OER

#### The Nitrogen Cycle

Fifth graders investigate the nitrogen cycle and examine the concepts of decomposition and nitrification. Students participate in a class discussion about the creation of waste and ammonia compounds, then using nitrogen cycle cut-outs...

Lesson Planet: 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...

Lesson Planet: Curated OER

#### Activity #19 Oxygen For Yeast

Students observe and record what occurs when yeast is added to hydrogen peroxide. They indicate why a chemical reaction (decompostion) must have occurred during the experiement. Pupils explain why yeast was used. Students comprehend the...

Lesson Planet: Curated OER

#### Down the Drain

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...

Lesson Planet: Curated OER

#### Rate of Decomposition

Students experiment with the decomposition rate of garbage. They discover that environments are fragile and need to be protected and resources are not always used wisely. They then think about their own environment and then about the...

Lesson Planet: Curated OER

#### Forest Floor Terrarium

Pupils 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...

Lesson Planet: Curated OER

#### 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...

Lesson Planet: Curated OER

#### 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...

Lesson Planet: Curated OER

#### Decomposition, Soil, and Life Cycle Research

Students conduct background research on the decomposition process, soil composition, and the life cycle using the resources provided for Internet searches. They work in collaborative groups to research topics as a particular plant, soil...

Lesson Planet: Curated OER

#### Vermicomposting

Third graders study vermicomposting. In this vermicomposting instructional activity, 3rd graders prepare to begin a unit on decomposition by constructing a worm bin. Students collect worms to be used later in experiments.

Lesson Planet: Curated OER

#### Stoichiometry

In this stoichiometry worksheet, students calculate balance the chemical equations and then calculate the moles needed to complete or activate the chemical reaction. Students also calculate the volume or grams needed for each chemical...

Lesson Planet: Curated OER

#### Stoichiometry Homework: 3

In this stoichiometry worksheet, students balance chemical equations. Students apply the concepts of stoichiometry to solve for each problem provided.

Lesson Planet: Curated OER

#### Chemical Reactions

In this chemical reactions worksheet, 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 worksheet has 2 problems to solve.

Lesson Planet: Curated OER

#### Integrals by Partial Fractions

Learners 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...

Lesson Planet: 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"...

Lesson Planet: 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...

Lesson Planet: Curated OER

#### Litter Garden

Students 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 record...

Lesson Planet: 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.

Lesson Planet: 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...

Lesson Planet: 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.

Lesson Planet: Curated OER

#### Deconstructing, Decomposition and Compost

Students create and tend to an outdoor compost pile. They research about decomposition and composting. They create two activities for their peers to complete.

Lesson Planet: 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.
