Unit A - Interaction and Ecosystems

Unit Overview
Ecosystems develop and are maintained by natural processes and are impacted by human action. To foster an understanding of ecosystems, this unit develops students' awareness of their components and interactions, as well as natural cycles and processes of change. Building on this knowledge, students investigate human impacts, and engage in studies that involve environmental monitoring and research. By reflecting on their findings, students become aware of the intended and unintended consequences of human activity, and recognize the need for responsible decision making and action.

Unit B - Plants for Food & Fibre

Unit Overview
Humans have always depended on plants as a source of food and fibre, and to meet a variety of other needs. To better meet these needs, technologies have been developed for selecting and breeding productive varieties, and to maximize their growth by modifying growing environments. ( Plant Biotechnology Resource) Long-term sustainability requires that we become aware of the practices we use, and examine impacts of these practices on the larger environment.   Alberta Environment (Website)

Unit C - Heat and Temperature

Unit Overview
The production, transfer and transformation of heat energy plays an important role in meeting human needs. In learning about heat, students investigate sources and uses of heat energy and consider the impact of their use on our long-term ability to meet energy needs. In focusing their studies, students explore different applications, investigate the scientific principles involved, and consider questions about the nature of heat. The particle model of matter is introduced to help students explain their observations and understand relationships between heat ( Thermal energy) and temperature.

Unit D - Structures and Forces

Unit Overview
Structures can be found in both natural and human-constructed environments, serving a variety of purposes and taking a wide range of forms. In learning about structures students investigate the properties of materials used, and test them under different loads and forces. They examine different ways that structural components are configured, analyze forces involved and investigate resulting effects on structural strength and stability. As part of their study, students also examine construction methods used in past and present, and learn how science and technology link together in developing safe and efficient designs that meet human needs.

Unit E - Planet Earth

Unit Overview
The scientific study of Earth is based on direct observation ( images) of landforms (Natural Resources - Canada) and materials that make up Earth's surface, and the sample evidence we have of Earth's interior. By studying this evidence, we discover patterns in the nature and distribution of the Earth's materials, and in the kinds of changes that take place. This knowledge can be used in developing models for geologic structures and processes- models that help both scientists and students enlarge their understanding of their observations, and guide further investigation and research.
