2. Look up the word ‘physician’. What does it mean?

3. What causes cholera disease?

4. What is ‘miasma’?

Activity 3.3 Detecting and treating disease

5. Why did John Snow order that the handle be removed from the Broad Street pump?

Activity 3.3 Detecting and treating disease

Activity 3.4 Defending against infectionNotebook: Defending against infection1. List two barriers that prevent pathogens entering the human body and

explain how they work.

2. What is the role of the white blood cells called phagocytes in protecting us from disease?

Activity 3.4 Defending against infection

3. Explain how the white blood cells called lymphocytes destroy pathogens that enter our blood.

4. Do you know how the parts of the immune system work together to prevent disease? Make a concept map using the following terms:-

Lymphatic vesselsLymph fluidThymusWhite blood cellsPhagocytesLymphocytesSpleenBone marrowLymph nodes

Lesson Outcomes Checklist Part 3NAME:

ACTIVITYLESSON OUTCOMESAt the end of these activities I can:

Please indicate if you achieved each learning

outcome:

= Yes

? = Partly

X = No

Activity 3.1 What is a disease?

list infectious diseases and suggest their causes

Activity 3.2 What causes disease?

identify the main types of pathogens that cause diseases in humans

list the pathogens, symptoms, methods of spread and treatments of several diseases

Activity 3.3 Detecting and treating disease

Describe the role of an epidemiologist

Recount how John Snow used his scientific knowledge of the intestinal damage of cholera disease to determine that it was water-borne, which led to his finding the source of the outbreak, which led to improved public health.

Activity 3.4 Defending against infection

identify the cells, tissues and organs that are part of the immune system

explore and summarise the three lines of defence the body uses against disease; namely the physical and chemical barriers, phagocytes and lymphocytes

Activity 3.5 How have scientists contributed to our understanding of disease?

summarise how scientists have contributed to our understanding of disease and immunity

appreciate how the work of scientists through time have significantly affected my life and the lives of others
