Year 9 Science Notes

Compare body systems in coordinated responses and explain a negative feedback mechanism.

Compare reproductive cells, organs and processes and connect them to species survival.

Represent carbon movement through Earth systems and explain key biological and chemical processes.

Use wave and particle models to describe energy transfer through media and evaluate model usefulness.

Analyse inputs, useful outputs, transfers and transformations in simple systems.

Explain changes in atomic models and how natural radioactive decay can produce more stable atoms.

Model atomic rearrangement using word and simple balanced equations.

Explain how publication, scrutiny, replication and evidence refine scientific knowledge.

Investigate reciprocal relationships between scientific understanding, technologies and engineering.

Analyse how evidence, trust, needs, values and access affect research priorities and adoption.

Develop testable relationship questions, reasoned predictions and explanatory models.

Plan controlled methods, precision, sample size, risk and ethical or intercultural considerations.

Construct tables, graphs, statistics, models and relationships to analyse scientific data.

Evaluate methods and claims, construct evidence arguments and communicate for purpose and audience.
