Describe the human digestive system, including the functions of the organs involved (limited to mouth, oesophagus, stomach, small intestine, large intestine and anus), and know that many vertebrates have a similar digestive system.

Know that animals, including humans, need an adequate, balanced diet in order to be healthy.

Know the stages in the life cycle of a flowering plant.

Describe how flowering plants reproduce by pollination, fruit and seed production, and seed dispersal.

Describe seed germination and know that seeds, in general, require water and an appropriate temperature to germinate.

Describe how plants and animals are adapted to environments that are hot, cold, wet and/or dry.

Describe the common adaptations of predator and prey animals.

Use the particle model to describe solid, liquids (including solutions) and gases.

Understand that substances can be gaseous and know the common gases at room temperature (limited to oxygen, carbon dioxide, water (vapour), nitrogen and hydrogen).

Know that the ability of a solid to dissolve and the ability of a liquid to act as a solvent are properties of the solid and liquid.

Know the main properties of water (limited to boiling point, melting point, expands when it solidifies, and its ability to dissolve a range of substances) and know that water acts differently from many other substances.

Describe the processes of evaporation and condensation, using the particle model and relating the processes to changes in temperature.

Understand that dissolving is a reversible process and investigate how to separate the solvent and solute after a solution is formed.

Investigate and describe the process of dissolving, and relate it to mixing.

Identify a range of forces (limited to gravity, applied forces, normal forces, upthrust, friction, air resistance and water resistance).

Know that an object may have multiple forces acting upon it, even when at rest.

Use force diagrams to show the name and direction of forces acting on an object.

Investigate how sounds are made by vibrating sources.

Describe sounds in terms of high or low pitch and loud or quiet volume.

Investigate how to change the volume and pitch of sounds.

Know the difference between a magnet and a magnetic material.

Know that forces act over a distance between magnets, and between a magnet and a magnetic material.

Know that magnets can have different magnetic strengths.

Know that the Earth is surrounded by a layer of air called the atmosphere, which is a mixture of different gases (including nitrogen, carbon dioxide and oxygen).

Understand that most water on Earth is not pure and has dissolved substances in it.

Understand that pollution is the introduction of substances by humans that harm the environment and identify examples of pollution.

Describe the water cycle (limited to evaporation, condensation and precipitation).

Describe the orbit of the Earth around the Sun (limited to slight ellipse, anticlockwise direction and the duration).

Describe how the tilt of the Earth can create different seasons in different places.

Know that a satellite is an object in space that orbits a larger object and a moon is a natural satellite that orbits a planet.
