Year 7 Science Notes

Develop testable questions and reasoned hypotheses, then identify independent, dependent and controlled variables.

Plan and improve investigations so comparisons are fair, risks are managed and methods can be reproduced.

Organise and analyse data, identify trends and anomalies, and evaluate conclusions and claims using evidence and limitations.

Explain why biological diversity is classified and use and develop dichotomous keys based on observable features.

Interpret food webs and predict how changes to biotic and abiotic factors can affect populations.

Use ecosystem models to distinguish energy flow from matter transfer and recycling.

Use particle theory to explain physical properties and distinguish pure substances from mixtures.

Select and sequence separation techniques by matching differences in physical properties to mixture components.

Model rotation, revolution and changing relative positions to explain day, year, Moon phases and seasons.

Use and evaluate Earth-Sun-Moon models to explain eclipses and predictable tidal patterns.

Represent multiple contact and non-contact forces and relate balanced or unbalanced net force to changes in motion.
