Students investigate temperate forest ecosystems. In this environmental lesson, students discover different forms of decomposition and its effect on the environment.

Students investigate methods of decomposition in order to make compost. In this decomposition science lesson, students set up compost bags using food and materials which decay over time. The initial lesson is approximately 30 minutes,...

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...

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...

Students 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...

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...

Written for an agriculture curriculum, this presentation on organic matter is also informative for gardening or horticulture classes. It details the chemical makeup, affecting factors, functions, maintenance, and composting to create a...

Learners define the term chemical reaction, identify the reactants and products in a chemical reaction, distinguish between decomposition and synthesis reactions and construct reactions using food items.

Students explore how landfills function. In this landfill lesson, students explore the use of landfills and the decomposition process by creating a model landfill. Students discuss pros and cons to landfills and how potential problems...

Students explore the process of decomposition in plants. In this plant biology activity, students use a cleaned out pumpkin and observe how the decomposition process takes place. Students write down adjectives to describe the pumpkin.

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...

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...

Pupils 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...

A 12-page midterm exam sample can be given to young scientists in preparation for an exam. This particular installment is geared toward a class that delves into both ecology and chemistry concepts. There is no way to separate the 50...

Pupils create their own compost.  In this soil lesson, students fill a bag with waste and soil, in order to create a mini compost bin. Pupils observe the baggies over a 6 week period, they record their findings and collect data on...

Students conduct an experiment to determine how much hydrogen peroxide (H2O2) is actually in a store-bought solution of H2O2.

Students explore organic and inorganic objects. In this environmental lesson students perform a composting experiment using flowers in different soils. Students record their observations.

In this reactions activity, students predict the products of 5 equations and write the equations for 5 reactions using their knowledge of types of reactions.

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...

Learners 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.

Students research cafeteria composting. In this composting lesson plan, students design a vessel that would allow the cafeteria staff to collect food scraps for composting. Then students build a prototype and present it to the class....

In this writing chemical reactions worksheet, students solve 15 problems on their own paper using a 3 step-problem solving approach. In addition, students write six balanced equations and classify each reaction. They also write equations...

In this balancing equations worksheet, students balance twelve equations by placing the proper coefficients in front of reactants and products and they identify the type of reaction each equation represents.

In this chemical reactions worksheet, students learn about the 5 types of chemical reactions as well as endothermic and exothermic reactions. Students are given 5 equations to balance and they identify the type of reaction for each...
