Students create a compost pile and chart changes as the materials decompose. Students draw pictures of items placed into their "landfill" and predict how and whether the item will change or not. After two weeks, students write...

In this chemical reactions worksheet, students fill in 12 blanks, determine if 5 statements are true or false, match 4 types of reactions with their description and solve 2 problems related to balancing equations and chemical reactions.

In this diagonalizing a matrix worksheet, students explore matrix factorization and use diagonal decomposition. This two-page worksheet contains examples, explanations and four practice problems.

In this ocean pollution learning exercise, students read the stewardship activities for ocean pollution. Students list 3 ways to help reduce pollution. Students then draw or write the items in the correct order of decomposition along the...

In this Calculus worksheet, students evaluate problems with integrals that require the use of the trapezoidal rule, Simpson’s rule and decomposition into partial rations.  The two page worksheet contains sixteen problems. ...

In this integrals worksheet, students solve seventeen integral problems.  One problem covers completing the square, one curve length, one partial fraction decomposition, one Simpson's rule, and several are trigonometric integrals.

In this integral worksheet, students integrate eight problems using partial fraction decomposition.  A review on partial fractions is included at the top of the worksheet.

Students observe the difference between degradable and non-degradable wastes. They create their own landfill in a jar by adding four or five pieces of garbage and then covering it with dirt and water. They make observations on what they...

In this 3-day place-value activity, upper-elementary kids investigate the base 5 and base 2 systems as an introduction to exponents and powers. They create a pocket chart to help ground their understanding of bases, exponents, and...

Learners investigate the decomposition process and the parameters which influence the rate at which it occurs. They design a "controlled" experiment by comparing decomposition rates between two compost piles. Analysis questions include...

In this unit of lessons, students examine solid waste and recycling. They discover the concept of decomposition. They also observe the decomposition process and make observatins.

Young scholars work together in groups to report on different topics related to decomposition. They answer questions and share their answers with the class. They discuss any topic that is unclear.

Students examine the following concepts: If water supplies contain materials which rot or decompose, oxygen is used. Decay and decomposition require vast supplies of oxygen. The use of oxygen for decay of wastes may be a life or death...

Second graders work in groups to bury a variety of trash items and arrange them in a mini-landfill. They predict which items will biodegrade and then keep records of what the items look like every ten days. Students consider how...

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.

Young scholars 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...

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...

Young scholars 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.

Students study decomposition. In this decomposition lesson plan, students discuss the background information about decomposition. Students then complete the 'Chew It Twice' worksheet.

Young scholars 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...

In this limestone worksheet, students name three sources of calcium carbonate, write the chemical formula, and determine the three elements found in calcium carbonate. This worksheet has 7 short answer and 3 problems to solve.

For 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.

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...

For this environment worksheet, 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 it can...
