Year 4 Science

Autumn Term


In this unit the boys will identify common appliances that run on battery and mains electricity, and name some appliances that do the same job but are operated manually. They will learn the names and functions of simple electrical components including batteries, bulbs, buzzers, wires and switches. They will understand the need for a complete loop for a bulb to light or a buzzer to buzz, and will construct simple circuits to light a bulb and make a buzzer buzz. They will then insert a switch into the circuit to turn the bulb/buzzer on and off. 

Dangers to Living things

In this unit children will work towards answering the Quest question ‘How can changes to the environment affect the things that live there?’ They will construct and interpret food chains, identifying producer, prey, consumer and predator. They will realise that the availability of food is an important factor when considering how animals respond to change in the environment. Children will investigate the effect of a small change to an environment by placing carpet or other covering on the ground, and will consider the impact of larger changes to the environment such as fire and flood. They will consider how humans can reduce the impact of some environmental changes. They will finish by answering the Quest about the effects on pond life of diverting a river to build new houses, when the original course of the river feeds into the pond. 

Spring Term

Summer Term

Grouping Living Things

We will be explaining how living things can be classified into different groups such as vertebrates and invertebrates as well as looking at how both animals and plants have adapted to their environment. We will also study different animal and plant habitats and recognise that these habitats can be affected by humans. This topic includes a visit to a local area for pond dipping and following an eco-trail. 

Changes of state 

We will be looking at the differences between states of matter and the processes by which those states can change. We will also look at how temperature affects the change of state of a variety of materials.
