|
Pathogens are microorganisms that cause infectious disease. |
|
What are pathogens? Microbe blind date activity.
Students not involved answer the questions on the work sheet. (found in T drive) |
|
|
|
Students should be able to describe the non-specific defence systems of the human body against pathogens, including the:
- skin
- nose
- trachea and bronchi
- stomach. |
|
What are the humans natural defence systems against pathogens? Label an outline of the human body with the bodies natural defences |
|
|
|
Students should be able to explain the role of the immune system in the defence against disease. |
|
What is the role of the immune system in the defence against disease? |
|
|
|
If a pathogen enters the body the immune system tries to destroy the pathogen. |
|
How does the immune system respond if a pathogen enters the body? |
|
|
|
White blood cells help to defend against pathogens by:
- phagocytosis
- antibody production
- antitoxin production. |
|
How do white blood cells help to defend against pathogens? (give 3 ways) Model the effects of white blood cells using plasticine or MWB. Take photos and stick into students books. |
|
|
|
Students should be able to explain how diseases caused by viruses, bacteria, protists and fungi are spread in animals and plants. |
|
How do the different pathogens spread in animals and plants? Put glitter onto your hand and greeting students at the door see how the glitter transmits around the classroom.
Each student gets a test tube of water except for one who gets a weak acid. Students swap with 3 others in the room. Then work backwards to try and establish who started with the disease. Test with Universal indicator solution or paper to see they have the disease (red means infected) |
|
|
|
Students should be able to explain how the spread of diseases can be reduced or prevented. |
|
How can the spread of diseases be reduced or prevented? Watch this video before showing a class. Consider if it is appropriate, in particular with any ASD students in the class.

|
|
Pathogens may be viruses, bacteria, protists or fungi. |
|
What four categories can pathogens fall into? . |
|
|
|
Pathogens may infect plants or animals and can be spread by direct contact, by water or by air. |
|
What can pathogens infect and how are they spread? |
|
|
|
Bacteria and viruses may reproduce rapidly inside the body. |
|
What do bacteria and viruses do once inside the body? |
|
|
|
Bacteria may produce poisons (toxins) that damage tissues and make us feel ill. |
|
How do bacteria make us feel ill? |
|
|
|
Viruses live and reproduce inside cells, causing cell damage. |
|
How do viruses cause damage to the cells? EW: (Construct a matrix map) To compare fungi, virus, bacteria and protists to include size, site of reproduction and effects in the body |
