Science

Electrical Conductors and Insulators will be the focus this half term. The Cambridge Primary Learning Objectives are outlined below.

Learning Objectives

Investigate how some materials are better conductors of electricity than others.

Investigate how some metals are good conductors of electricity and that most other materials are not.

Know why metals are used for cables and wires and why plastics are used to cover wires and as covers for plugs and switches.

Can predict and test the effects of making changes to circuits including length or thickness of wire and the number and type of components.
Can represent series circuits with drawings and conventional symbols.

Food Chains will be the focus this half term. The Cambridge Primary Learning Objectives are outlined below. 

Learning Objectives

Know how food chains can be used to represent feeding relationships in a habitat and present these in text and diagrams.

Know that food chains begin with a plant (the producer), which uses energy from the Sun.

Know and understand the terms ‘producer’, ‘consumer’, ‘predator’ and ‘prey’.

Children have explored and can construct food chains in a particular habitat.

Reversible and Irreversible Changes will be the focus this half term. The Cambridge learning objectives for the topic are outlined below.

- Can distinguish between reversible and irreversible changes.

- Explore how solids can be mixed and how it is often possible to then separate them again.

- Observe, describe, record and begin to explain changes that occur when some solids are added to water.

- Explore how when solids do not dissolve or react with the water they can be separated by filtering, which is similar to sieving.

- Explore how some solids dissolve in water to form solutions and although the solid cannot be seen, the substance is still present

Human Organs and Systems will be the focus at the start of this year. The Cambridge Primary learning objectives are outlined below for this topic. 

Learning objectives

- Can identify the position of major organs in the body. 
- Can describe the main functions of the major organs of the body. 
- Can explain how the functions of the major organs are essential. 
- Can use scientific names for some major organs of body systems (heart, lungs, kidneys, stomach/intestines, brain).
