function.
 Also describes the organisation of life at the cellular level.
Overarching learning outcomes:
In building understandings about the immune system, students will integrate:
 understanding that the immune system works to fight infection in our bodies (scientific knowledge)
 an investigation into the immune system and how it functions to fight specific diseases (scientific practice)
 understanding that scientific knowledge can be used to help people (nature of science).

 use an animation from the
Science Learning Hub to explore
the immune system
 use a camera to take videos clips
of the immune response drama.

Management/materials:
 Resources: www.sciencelearn.org.nz/Contexts/Fighting-Infection, microscopes
 Equipment for the student activity Spreading diseases (optional)
Assessment:
 Imagine you are an immune cell, bacterium or virus. Write a short story about what happens to you in the body to show your understanding
of the immune system.
 Alternatively, the mind map could be an assessment activity.

 In small groups or as a class,
read the article Infection.
Discuss terms such as
‘microorganisms’, ‘pathogenic’,
‘vaccination’. This could be
done as a class using an IWB –
scientific words could be
highlighted and discussed.
Key student outcomes
 Students will understand that
snot is formed by the body to
protect the body against
invading particles and ‘germs’
that may cause an infection.
 Students will know that
infection is the invasion of
pathogens into the body.
