By studying key processes in the carbon cycle, such as photosynthesis, composting and anaerobic digestion, students learn how nature and engineers "biorecycle" carbon. Students are exposed to examples of how microbes play many roles in various systems to recycle organic materials and also learn how the carbon cycle can be used to make or release energy.

The foamy fun of "Elephant's Toothpaste," also known as the catalytic decomposition of hydrogen peroxide, helped Camille Schrier win her job as Miss America 2020! In this episode, Camille re-creates this winning chemical reaction and teaches us all about the science of catalysts and decomposition. Explore questions such as: What is a catalyst? What does a catalyst do? Why do we need a catalyst to make "Elephant's Toothpaste"? It’s a HUGE, wonderful, foamy mess that's all powered by science! Developed for students in grades 6 - 10.

Students bury various pieces of trash in a plotted area of land outside. After two to three months, they uncover the trash to investigate what types of materials biodegrade in soil.

Students investigate decomposers and the role of decomposers in maintaining the flow of nutrients in an environment. Students also learn how engineers use decomposers to help clean up wastes in a process known as bioremediation. This lesson concludes a series of six lessons in which students use their growing understanding of various environments and the engineering design process, to design and create their own model biodome ecosystems.

In a multi-week experiment, students monitor the core temperatures of two compost piles, one control and one tended, to see how air and water affect microbial activity. They daily aerate and wet the "treated" pile and collect 4-6 weeks' worth of daily temperature readings. Once the experiment is concluded, students plot and analyze their data to compare the behavior of the two piles. They find that the treated pile becomes hotter, an indication that more microbes are active and releasing heat. Through this activity, students see that microbes play a role in composting and how composting can be used as a carbon management process.

Students explore the concept of biodegradability by building and observing model landfills to test the decomposition of samples of everyday garbage items. They collect and record experiment observations over five days, seeing for themselves what happens to trash when it is thrown "away" in a landfill environment. This shows them the difference between biodegradable and non-biodegradable and serves to introduce them to the idea of composting. Students also learn about the role of engineering in solid waste management.

In this lesson, students will be introduced to the idea of decomposition. Specifically the lesson caters to math word problems, but could be easily modified to any subject (as found in the modificaitons section of the lesson plan). Students will engage with each other and the vocab to work through an easy process to decompose word problems into manaeagable pieces as a strategy to solve. All activities are low prep and can be modified to your needs. This can be a stand alone lesson or expanded by using Part 2 and Part 3 to deepen understanding through coding activities. 

This lesson expands upon the ideas of decomposition by using GameChangineer to incorporate commands to create a coded mini game from decomposing word problems. Students will assist the teacher in this guided lesson on how to create commands and use the website before engaing independently in Part 3. Activities are low prep with modifications included, but do require organized planning to implement effectively. If you have not done a lesson on decomposition, it is suggested you use Part 1 to help student's gain the necessary understandings of the processes used in this lesson. 

This is the final part of an extended lesson on decomposition. Students will create a word problem to decompose and then use GameChangineer to create a mini game that is reflective of the word problem and its solution. Students will be using the plan, design, and review process thourhgout their creations. A rubric and self reflection tool for the final products are included. Activities are low prep with modifications included, but do require organized planning to implement effectively. If you have not done a lesson on decomposition, it is suggested you use Part 1 to help student's gain the necessary understandings of the processes used in this lesson. If you have not done a lesson on writing commands and using GameChangineer, it is suggested you use Part 2 before implementing this independent activity. 

Students design and conduct experiments to determine what environmental factors favor decomposition by soil microbes. They use chunks of carrots for the materials to be decomposed, and their experiments are carried out in plastic bags filled with dirt. Every few days students remove the carrots from the dirt and weigh them. Depending on the experimental conditions, after a few weeks most of the carrots will have decomposed completely.

Students become “experts” and make creative presentations about the different ecological roles of producers, consumers, and decomposers at local and global scales.

Students learn about energy and nutrient flow in various biosphere climates and environments. They learn about herbivores, carnivores, omnivores, food chains and food webs, seeing the interdependence between producers, consumers and decomposers. Students are introduced to the roles of the hydrologic (water), carbon, and nitrogen cycles in sustaining the worlds' ecosystems so living organisms survive. This lesson is part of a series of six lessons in which students use their growing understanding of various environments and the engineering design process, to design and create their own model biodome ecosystems.

Hands on Chemistry is a resource designed for use in traditional, online, and blended high school Chemistry classrooms. It was developed by Blue Ridge PBS in collaboration with Virtual Virginia. In this video, Chemistry teacher Fred Mitchell demonstrates decomposition using Hydrogen Peroxide and catalyst Manganese Dioxide.

Students observe the decomposition of a pumpkin under controlled circumstances. These observations are used to take notes and develop questions.

This activity shows you how to make a mold terrarium using a jar and leftover food. Learners explore mold, an "icky but necessary" thing that helps living matter rot, return to the soil, and provide nutrients for other plants. If you use a variety of food scraps, with preservatives and without, you'll see the different kinds of mold and be able to compare the rate of growth on various foods. Note: don't put meat or fish in your mold terrarium--after a few days, these would start to smell very, very bad.

Students will use decomposition strategies to predict what will happen in a story based on the pictures through the use of the 5W and 1H question words. Students will identify the characters and setting of the story and make a prediction based on the information they gained from the images.These materials were created by CodeVA in partnership with George Mason University and were funded by the National Science Foundation under Grant Award #1837380

Students investigate what types of materials biodegrade in the soil, and learn what happens to their trash after they throw it away. The concepts of landfills and compost piles will be explained, and the students will have an opportunity to create their own miniature landfill in which the difference between organic and inorganic waste will become clear.
