Term 2

Background Information
The principal focus of science teaching in Upper Key Stage 2 is to enable pupils to develop a deeper understanding of a wide range of scientific ideas.
They should do this through exploring and talking about their ideas; asking their own questions about scientific phenomena; and analysing functions, relationships and interactions more systematically. At Upper Key Stage 2, they should encounter more abstract ideas and begin to recognise how these ideas help them to understand and predict how the world operates.
They should also begin to recognise that scientific ideas change and develop over time. They should select the most appropriate ways to answer science questions using different types of scientific enquiry, including observing changes over different periods of time, noticing patterns, grouping and classifying things, carrying out comparative and fair tests and finding things out using a wide range of secondary sources of information.
Pupils should draw conclusions based on their data and observations, use evidence to justify their ideas, and use their scientific knowledge and understanding to explain their findings.

In this unit the children will…
Identify and name the main parts of the human circulatory system, and describe the functions of the heart, blood vessels and blood
Recognise the impact of diet, exercise, drugs and lifestyle on the way their bodies function
Describe the ways in which nutrients and water are transported within animals, including humans
Work scientifically by exploring the work of scientists and scientific research about the relationship between diet, exercise, drugs, lifestyle and health

By the end of this unit….
All children will:
be able to identify and name the main parts of the human circulatory system.
be able to plan pattern-seeking enquiry.
be able to describe the ways in which nutrients and water are transported within animals, including humans.
be able to recognise the impact of diet, exercise, drugs and lifestyle on the way their bodies function.
be able to present findings from enquiries.
be able to record results using a line graph.
Most children will:
be able to explain the functions of the heart, blood vessels and blood.
draw conclusions based on their data and observations,
Some children will:
use evidence to justify their ideas, and use their scientific knowledge and understanding to explain their findings.

The children will explore:
What they know already (KWL grid)
What is the function of the heart?
Draw a human heart and label it with its main parts
What happens to the rate at which our hearts beat when we perform different exercise?
Plan own investigation—record using a line graph.
What are the funcions of the blood? Make components of the blood
Why do we need to drink water?
Research drugs, diet and exercise
iWhat We h materials allow electricity to pass through them?
Which metals are the best conductors of electricity?
What are the best conditions for dissolving sugar in the fastest time?
What is the best material for filtering?
Which changes cannot be easily reversed?
