By the end of Year 7 students explain how biological diversity is ordered and organised. They represent flows of matter and energy in ecosystems and predict the effects of environmental changes. They model cycles in the Earth-sun-moon system and explain the effects of these cycles on Earth phenomena. They represent and explain the effects of forces acting on objects. They use particle theory to explain the physical properties of substances and develop processes that separate mixtures. Students identify the factors that can influence development of and lead to changes in scientific knowledge. They explain how scientific responses are developed and can impact society. They explain the role of science communication in shaping viewpoints, policies and regulations.

Students plan and conduct safe, reproducible investigations to test relationships and aspects of scientific models. They identify potential ethical issues and intercultural considerations required for field locations or use of secondary data. They use equipment to generate and record data with precision. They select and construct appropriate representations to organise data and information. They process data and information and analyse it to describe patterns, trends and relationships. They identify possible sources of error in methods and identify unanswered questions in conclusions and claims. They identify evidence to support their conclusions and construct arguments to support or dispute claims. They select and use language and text features appropriately for their purpose and audience when communicating their ideas and findings.

It is based on the cognitive domain and assumes that learning should be structured from easy to difficult in the following 6 steps:

1. Remember

2. Understand

3. Apply

4. Analyze

5. Evaluate

6. Create

It is excellent for visual learners and the drag-and-drop components make these accessible to kinaesthetic learners. These activities aim to help students move up to higher levels of cognitive processing specifically, applying and analysing.

This lesson teaches students how to separate mixtures using magnetism, decantation, evaporation, filtration, chromatography and distillation.
