1. Variation in Species: Explain variation within and between species, distinguishing between continuous variation (e.g. height) and discontinuous variation (e.g. blood group), and between genetic and environmental causes
2. Evidence-Based Classification: Give reasons for classifying plants and animals based on specific characteristics, using evidence to justify classification decisions
3. Photosynthesis: Explain photosynthesis as the process by which plants use light energy to convert carbon dioxide and water into glucose and oxygen, and describe how mineral nutrients are absorbed through roots

2. Grade 7 · Students will be able to represent observations and data in order to recognize patterns in the data, the meaning of those patterns, and possible relationships between variables.

1. Fossils as Evidence: Analyse and interpret data from fossils to provide evidence of organisms and environments that existed long ago
2. Food Webs & Interdependence: Construct and interpret food webs showing the interdependence of organisms in an ecosystem, explaining how a change in one population affects others

3. Grade 7 · Students will be able to develop, revise, and use models to represent the students' understanding of phenomena or systems as they develop questions, predictions and/or explanations, and comm

2. Cells Under the Microscope: Understand that all living organisms are made of cells and use a light microscope to observe, interpret, and record cell structure

4. Grade 7 · Students will be able to engage in argument from evidence for the explanations the students construct, defend and revise their interpretations when presented with new evidence, critically ev

1. Drawing conclusions from evidence (age 12+): Identify patterns and trends in data, draw conclusions that directly address the hypothesis with quantitative reference to evidence, and evaluate the investigation by distinguishing between systematic and random errors and proposing targeted improvements
