- Science Understanding – “Cells are the basic units of living things and have specialised structures and functions. Multi-cellular organisms contain systems of organs that carry out specialised functions that enable them to survive and reproduce.”
- Science Inquiry Skills – “Construct and use a range of representations, including graphs, keys and models to represent and analyse patterns or relationships, including using digital technologies as appropriate.”
Learning Intention and Success Criteria: Students will be able to identify the structure and function of organs in the circulatory system and be able to name and describe the components of blood. Students will complete a labelled diagram of the heart and circulatory system and be able to describe how it works.
1. Work your way through the National Geographic – Heart Interactive. Label the blank heart diagram with the names of each structure, including the atria, ventricles, aorta and valves.
2. Watch the National Geographic Video – Cardiovascular system and then colour the cardiovascular diagram showing oxygenated (red) and deoxygenated (blue) blood.
3. Access the Blood Buddies – the Australian Red Cross Blood Service website and find out how you are tested for your blood type. Do you know what blood group you belong to? Create a graph (bar graph or pie chart) showing the different blood groups:
- O positive – 40%
- O negative – 9 %
- A positive – 31%
- A negative – 7 %
- B positive – 8%
- B negative – 2%
- AB positive – 2 %
- AB negative – 1%
- Australian Red Cross Blood Service – information for students
- Video – Human Circulatory System
- Video – The Heart and Circulatory System
- Labelled diagram – Chambers and valves of the heart
- Through the microscope – blood cells
- Scanning electron microscopic images of red blood cells
- Nice drawings of red and white blood cells
