Science
Jaxsen researched chemical changes related to waste and used that information to answer every question on the worksheet. He likely learned that chemical changes can produce new substances, and he practiced identifying how waste materials can be altered through processes such as decomposition, combustion, or recycling-related treatment. By completing the worksheet, Jaxsen showed he could gather information, read for key scientific ideas, and apply what he found to explain real-world waste issues. This activity helped him build science understanding about matter, change, and environmental impact in a way that a 12-year-old could connect to everyday life.
Tips
To deepen Jaxsen’s learning, he could compare chemical changes with physical changes in different kinds of waste and sort examples into each category. He could also create a simple flow chart showing what happens to a waste item during decomposition, burning, or processing, which would help him visualize cause and effect in science. A hands-on extension could be investigating how different materials break down over time and discussing which types of waste create more environmental concerns. Finally, Jaxsen could write a short explanation or present a mini poster about one waste-management method and how chemical change plays a role in it.

- Composting by Gail Gibbons: A clear introduction to how organic waste breaks down and changes through decomposition.
Learning Standards
- Science inquiry and research: Jaxsen gathered information from sources to answer questions, matching research-based learning and evidence use.
- Properties and changes of matter: The activity focused on chemical changes, including how waste materials can transform into new substances.
- Environmental science: The worksheet connected science concepts to waste management and human impact on the environment.
- Canadian Curriculum connections: This aligns broadly with grade 6–8 science expectations related to matter and energy, chemical change, and environmental stewardship (specific provincial codes vary).
