Describe the human respiratory system in terms of oxygen from the air moving into the blood in the lungs and know that many vertebrates have a similar respiratory system.

Name the parts of the human reproductive system.

Describe the physical changes that take place during puberty in humans.

Know that some diseases can be caused by infection with viruses, bacteria, parasites or fungi that can be passed from one host to another.

Describe how good hygiene can control the spread of diseases transmitted in water, food and body fluids, and describe ways to avoid being bitten by insect vectors.

Know that humans have defence mechanisms against infectious diseases, including skin, stomach acid and mucus.

Interpret food webs and identify food chains within them.

Know that some substances can be toxic and damage living things, and that these substances can move through a food chain/web.

Identify the energy source of a food chain/web and describe how energy is transferred through a food chain/web.

Know that the temperature at which a substance changes state is a property of the substance.

Know that gases have properties, including mass.

Understand that electrical conductivity and thermal conductivity are properties of a substance.

Identify and describe physical changes that are reversible.

Describe how temperature affects solids dissolving in liquids and relate it to the particle model.

Describe the difference between boiling and evaporation.

Understand that chemical reactions involve substances, called reactants, interacting to form new substances, called products.

Observe and describe the evidence that a chemical reaction has taken place (limited to a gas being produced, colour change and change in temperature).

Describe the difference between mass, measured in kilograms (kg), and weight, measured in newtons (N)

Describe the effect of gravity and know that when gravity changes, the weight of an object changes but the mass does not.

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

Describe the effect of different forces on an object at rest and in motion.

Recognise that the mass and shape of an object can affect if it floats or sinks.

Describe how a ray of light changes direction when it is reflected from a plane mirror.

Describe how a ray of light changes direction when it travels through different mediums and know that this is called refraction.

Use diagrams and conventional symbols to represent, make and compare circuits that include cells, switches, lamps and buzzers.

Make simple circuits and compare the brightness of lamps in series and parallel circuits.

Know that rocks can be classified as metamorphic, igneous and sedimentary, and describe the identifying features of each type of rock.

Describe the way fossils can form in sedimentary rocks.

Know that there are different types of soils and they can be classified based on their clay, sand and organic content.

Know that soil composition can change, which can support, or hinder, plant growth.

Describe the rock cycle and the formation of metamorphic, igneous and sedimentary rocks in terms of solidification, erosion, sedimentation, burial, metamorphism and melting.

Describe the relative position and movement of the planets, the Moon and the Sun in the Solar System.

Observe and describe the changes in the appearance of the Moon over its monthly cycle.
