Earth's resources and sustainable development

Fractional distillation of crude oil

Cracking fractions of crude oil

Polymer structures

Developing a reactivity series for metals

Extraction of metals by reduction

Life cycle assessments (LCAs)

In the Atmosphere and Changing Climate unit, pupils will build on their understanding of Earth's resources to learn about the evidence for the composition and evolution of the Earth's atmosphere and the impact of human activity on climate change.

In the Earth's Resources unit, pupils learned about the composition and structure of the Earth, and the rock cycle.

This unit covers crude oil, its role as a hydrocarbon source, and separation by fractional distillation. It explores cracking, metal reactivity, and extraction methods, including biological alternatives. Emphasis is on recycling, life-cycle assessments, and evaluating decisions.

Properties of Group 1

Properties of Group 7

Reactions of the halogens: including displacement practical

In the Chemical Analysis unit, pupils will build on their knowledge of the periodic table to explore various techniques for analysing substances and interpreting data.

In the Patterns in the Periodic Table unit, pupils learned about the arrangement of elements in the periodic table and the trends in properties of elements.

This unit explores how elements' reactions are related to electron arrangement and atomic number. It covers the properties of Groups 1, 7, and 0 and explains how these depend on outer electrons. It also predicts element reactivity and reactions based on their positions in the periodic table.
