A complete 60-day Grade 4 Science learning path aligned with the Alberta Program of Studies. Students investigate waste and responsible resource use, explore how wheels and levers transfer force, design moving devices and vehicles, and explain the behaviour of light and shadows. Learning emphasizes inquiry, hands-on investigation, evidence-based communication, environmental responsibility, and connections to Calgary communities and environments.

Students investigate the different kinds of waste produced at home, school, and in Calgary communities. They classify materials according to properties such as reusability, recyclability, biodegradability, and toxicity, and examine how waste is transported, processed, reused, recycled, or disposed of. Students explore the environmental and social effects of waste, including landfill use, litter, hazardous materials, and resource depletion. They analyze personal and community waste practices and develop an action plan based on the waste hierarchy: reduce, reuse, recycle, and recover. Throughout the topic, students collect data, represent findings in tables or graphs, evaluate evidence, and communicate realistic recommendations for reducing waste at school or home.
