1. Earth's Systems

1. States of Matter Vocabulary: Name and distinguish the three states of matter — solid, liquid, and gas — using properties vocabulary: hard, rigid, runny, flows, keeps its shape, fills its container; use 'change of state' to describe what happens when materials are heated or cooled
2. Shapes of land and water: Develop a model to represent the shapes and kinds of land (mountains, valleys, plains) and bodies of water (rivers, lakes, oceans) in an area
3. Preventing Erosion: Compare multiple solutions designed to slow or prevent wind or water from changing the shape of the land

2. Biological Evolution: Unity & Diversity

1. How animals adapt to environments: Identify how animals and plants are adapted to suit their environment and understand that adaptation may lead to evolution over time

3. Ecosystems: Interactions, Energy, and Dynamics

1. Pollination & Seed Dispersal: Understand the life cycle of flowering plants including pollination, seed formation, and seed dispersal
2. Water Transport in Plants: Investigate how water is transported within plants, using observations such as coloured water being drawn up through a stem

4. Matter and Its Interactions

1. Heating & Cooling Changes: Observe and describe that some materials change state when heated or cooled, and measure the temperature at which changes occur in degrees Celsius
2. Taking Apart & Rebuilding: Observe that an object made of a small set of pieces can be disassembled and made into a new object, understanding that the pieces still exist
3. Choosing the Right Material: Identify and compare the suitability of everyday materials for particular uses, explaining why specific materials are chosen for specific purposes
4. Properties of materials: Compare and group different kinds of rocks based on their appearance and simple physical properties such as hardness, texture, and colour
