Case Study: The Curious Case of the Crumbling Cliffs and the Spr

Develop a hypothesis that connects the crumbling cliffs to the measles outbreak.

Explain how the environmental changes caused by the weathering of the granite could have influenced the spread of the disease.

How is measles transmitted?

• Measles is transmitted through respiratory droplets.
• Measles is transmitted by direct skin contact.
• Measles is transmitted through contaminated water.
• Measles is transmitted via insect bites.

What is an incubation period? Why is it important in understanding the spread of a disease?

• The incubation period is the time when a person is immune to a disease.
• The incubation period refers to the duration of treatment for a disease.
• The incubation period is the time it takes for a vaccine to become effective.
• The incubation period is the time between exposure to a pathogen and the onset of symptoms; it is important for understanding disease spread.

Could the unusually high rainfall contribute to the spread of the measles? Explain.

What role could the seagulls and raccoons play in the spread of the measles?

• Seagulls and raccoons could potentially spread measles by contaminating surfaces or food after contact with infected individuals.
• Seagulls and raccoons are immune to measles and cannot spread it.
• Only humans can spread measles; animals have no role.
• Seagulls and raccoons can directly transmit measles through bites.

How could the school prevent future outbreaks?

• Increase class sizes to reduce contact
• Limit outdoor activities during school hours
• Implement regular health screenings and promote vaccination.
• Encourage students to share personal items

How might the collapse of the cliff and the measles outbreak be connected? Consider the role of the environment and animal vectors.

Create a diagram that shows both the rock cycle, and the possible transmission of the measles in Granite bay.
