Overview

In this learning sequence students investigate the role and structure of the circulatory system as well as focus on the functions of the heart and blood. Students learn about the urinary system, as the main part of the excretory system, and the function of the kidneys. Students investigate the structure and function of the skeletal and muscular systems in protecting and supporting the internal structures of the body and allowing body movement. 

There are opportunities for students to do a number of simple experiments involving the circulatory system and skeletal/muscular system. In addition, there are further exploration ideas and resources provided.  

Students are learning to:

• describe the structure of the circulatory or cardiovascular system

• describe the structure of the heart

• explain the circulation of blood between the heart, lungs and the rest of your body

• explain how exercise affects the circulatory and respiratory system

• conduct first-hand investigations to measure the effect of exercise on heart rate

• describe the roles of blood working with systems around your body and its composition

• investigate blood donation and possible uses of donated blood

• understand how the circulatory and respiratory systems work together to provide cells with oxygen and get rid of waste carbon dioxide

• describe how the urinary system removes wastes from the body and identify its parts

• investigate the structure of bones and muscles and describe the function of the skeletal and muscular systems

• tabulate, graph and analyse first hand and secondary data.

Outcomes

• LW3 Multicellular organisms contain systems of organs that carry out specialised functions that enable them to survive and reproduce

• LW3e Students describe the role of the digestive, circulatory, excretory, skeletal/muscular and respiratory systems in maintaining a human as a functioning multicellular organism.

• LW4 Scientific knowledge changes as new evidence becomes available, and some scientific discoveries have significantly changed people's understanding of the world.

• LW4a Students research an example of how changes in scientific knowledge have contributed to finding a solution to a human health issue.

• LW4c Students describe, using examples, how developments in technology have contributed to finding solutions to a contemporary issue, eg organ transplantation, artificial joints/limbs, treatment for diabetes, asthma, kidney or heart disease.

• LW4d Students give examples to show that groups of people in society may use or weight criteria differently in making decisions about the application of a solution to a contemporary issue, eg organ transplantation, control and prevention of diseases and dietary deficiencies.

• SC4-1VA appreciates the importance of science in their lives and the role of scientific inquiry in increasing understanding of the world around them

• SC4-6WS follows a sequence of instructions to safely undertake a range of investigation types, collaboratively and individually  

• SC4-7WS processes and analyses data from a first-hand investigation and secondary sources to identify trends, patterns and relationships, and draw conclusions

• SC4-9WS presents science ideas, findings and information to a given audience using appropriate scientific language, text types and representations 

• SC4-14LW relates the structure and function of living things to their classification, survival and reproduction

• SC4-15LW explains how new biological evidence changes people's understanding of the world
