Circulatory System

Year 6

Unit Overview

This project teaches children about the transport role of the human circulatory system, its main parts and primary functions. They learn about healthy lifestyle choices and the effects of harmful substances on the body.


Fun and interactive scientific investigation in to the impact of exercise on our bodies.


We will be writing non-chronological reports detailing how to stay healthy


We will take part in a range of exercise outside and investigate its impact on our circulatory system.

Unit Sequence: Learning Intentions

  1. Name and describe the purpose of the circulatory system and the functions of the heart, blood vessels and blood.

  2. Take accurate, precise and repeated measurements in standard units, using a range of chosen equipment.

  3. Structure and function of the heart

  4. To understand the function of blood.

  5. To understand the function of blood vessels.

  6. To carry out an investigation in to classifying foods

  7. To investigate the effects of smoking, drugs and alcohol on the human circulatory system.

  8. Plan an investigation in to the effect of exercise on heart rate.

  9. Carry out an investigation in to the effect of exercise on heart rate.

  10. Create a results table and analyse the results of my investigation, drawing conclusions.

Scientific Enquiry: Investigations

What can your heart rate tell you?

    • Plan different types of scientific enquiries to answer questions, including recognising and controlling variables where necessary.

    • Record data and results of increasing complexity using scientific diagrams and labels, classification keys, tables, scatter graphs, bar and line graphs.

    • Report and present findings from enquiries, including conclusions, causal relationships and explanations of and degree of trust in results, in oral and written forms such as displays and other presentations.

    • Recognise the impact of diet, exercise, drugs and lifestyle on the way the human body functions.


The unit will culminate in children performing a five minute presentation in small groups to the rest of the class based around a chosen part of our topic.
