1. How are diseases spread?
L/O: Explain how infectious diseases are spread. S/C: EBI: Evaluate how the spread of disease has reduced. Great: Describe how pathogens are spread Good: Define the term pathogen

2. Starter- Can you identify these?

3. Starter- Can you identify these?
Fungi
Virus
Virus
Bacteria
Protoctist
Some are harmless and/or useful
Whilst others are harmful and cause illness/infectious diseases
The microbes that cause disease are called PATHOGENS

4. What is a pathogen? Anything that causes a disease: Virus Bacteria
Protozoa

5. Which type of pathogen is the cause of these diseases?
Athletes' foot
Influenza
Measles
Chicken pox
Food poisoning
Cholera
Malaria
Rubella TB
AIDS

7. Make a list of all the ways that disease can spread
Direct (Physical) contact
Body fluids
Mother to unborn baby
Shared needles/syringes
Air particles
Food
Water
Vector (insects)
Each method needs to be explained including subcategories e.g body fluids include blood as well as fluids secreted during sexual intercourse...
Give yourself a mark out of 8

8. You are given these two sheets of paper plus a set of disease cards
Tetanus
You are given these two sheets of paper plus a set of disease cards
Arrange each card according to the method that the disease is transmitted
Leave the cards on top of the 2 sheets of paper- DON’T MOVE!
AIDS
Malaria
Salmonella

11. Fill in the table You will be given a blank table like this one:
Distribute disease fact sheets to groups. Students use each one and then circulate amongst the class. Information sheets should be placed around the class and students work their way round and fill in a grid
Write the 8 methods of disease transmission in the first column
Use the disease fact sheets to fill the rest of the table in.

True or False
Pathogens are microbes that cause disease.
True- they cause infectious diseases when spread.

19. True or False
Bacteria multiply by dividing their cells in two.
True – Virus’s need a host cell though- hence debated whether they are living or not.

True or False
It is dangerous to have microbes on your hands.
False- not all microbes are harmful.
