Science

In the Carbon Cycle and Climate Change unit, pupils will build on their understanding of fuels and energetics to learn about the carbon cycle and the impact of human activity on climate.

In the Understanding chemical reactions unit, pupils learnt about how atoms move around to form new substances in chemical reactions and about some common types of chemical reactions.

This unit examines energy changes in state, exothermic and endothermic reactions, and energy transfers in various processes. It emphasises objectivity, accuracy, and precision in scientific enquiries, data interpretation, and the use of tables, graphs, and reliable methods.
