Strand A: STEM Skills and Connections

Using research, experimentation and design processes, coding, and understanding what people have contributed to science and technology (expectations A1, A2, A3).

  1. Who helped build science and technology? Analysing what different communities have contributed to science and technology (A3.3). Invention × 3

Strand B: Life Systems

How plants benefit society and the environment, how human activity affects them, and what plants are, how they are used and how they respond to their surroundings (expectations B1, B2).

  1. What does a plant need from its land? Describing what plants need, including water and nutrients, and what can threaten their survival (B2.1). Invention

Strand C: Matter and Energy

The effects of forces on society and the environment, and how forces cause motion and changes in motion (expectations C1, C2).

  1. When wind and earth strike what people built Assessing what the forces of natural phenomena do to natural and built places, and how people responded (C1.1). Story × 2

Strand D: Structures and Mechanisms

The importance of form, function, strength and stability in structures, and the factors that affect them (expectations D1, D2).

  1. What is a dome made of? The properties of materials in building, and how forces such as wind can affect a structure (D2.5, D2.6). Place

Strand E: Earth and Space Systems

The importance of soils, how human activity affects them, and their composition, types and the practices that affect their health (expectations E1, E2).

  1. What is added to the soil, and which soil suits which crop? Identifying what is added to soil, and examining soil types and the crops each suits (E2.2, E2.3). Invention
