In this activity, students investigate the fascinating and complex process of decomposition and lay the foundation for deeper understanding of concepts related to matter and energy transfer in ecosystems. Through exploration and discussion, students go beyond simple definitions. Instead, students discover key characteristics of decomposition as they struggle with creating a sequence for decomposing wood and leaves. They learn the difference between physical decomposition and chemical decomposition and that many things contribute to decomposition, but certain organisms are classified as decomposers. They also search for and discuss evidence of decomposers, make model diagrams to further develop their ideas about the process of decomposition, and discuss decomposition and its role in the cycling of matter. Finally, students are challenged to recognize the evidence and impact of decomposition in the ecosystems they explore.
- Explore, observe, and compare samples of decomposing materials and use reasoning to determine the level of decomposition among them
- Search for and classify decomposers (or evidence of them) as fungi, bacteria or invertebrates
- Investigate and discuss decomposition as the process of breaking down dead organisms and their waste materials into smaller and simpler forms of matter
- Create a model diagram for the process of decomposition
- Discuss the role decomposers play in making matter available to living plants
A free online course created by TRAC Tenant Resource and Advisory Centre and the Justice Education Society. Designed for first-time renters, the course covers both practical and legal topics to consider before deciding to rent. Students can complete activities such as creating a budget, thinking about their housing needs, preparing a list of references, writing a cover letter and pet resume, and ordering a credit report. The course is video-based, and sections can be viewed in any order. Students who complete the course and pass the final exam earn a certificate that can be presented to landlords when they apply for tenancy. By completing the course, students will be better equipped to find rental housing and succeed in their tenancies. Core skills, such as financial literacy, smart decision making, effective communication, and problem solving are a key focus of the material.
