Population of Salisbury, MD 30,484 How long will it take the virus to consume the entire city?

VIRUS A 500 people are infected by the zombie virus EVERY DAY! VIRUS B There is one zombie. Every zombie infects one person to stay alive each day. VIRUS B There is one zombie. Every zombie infects one person to stay alive each day. Which strand of the ZOMBIE VIRUS will infect the entire population of Salisbury quickest? Don’t tell anyone what you picked! Write it down with a brief explanation.

VIRUS A 500 people are affected by the zombie virus EVERY DAY!

Day 1 Day 2 Day 3 Day 4

Day of Infection Total Infected Fill in the following table of values based on the spread of the zombie virus Scenario people are affected by the zombie virus EVERY DAY!

Day of Infection Total Infected ,000 21,500 32,000 42,500 53,000 Fill in the following table of values based on the spread of the zombie virus How fast is the virus spreading? How fast is the virus spreading? How many people are infected?

VIRUS B Only one person is affected day one, then two people day two, then four people day four, and so fourth. VIRUS B Only one person is affected day one, then two people day two, then four people day four, and so fourth.

Day 0 Meet Patient Zero Every day, each zombie infects one more person Day 1 New Infected

Day 2 New Infected

Day 3 New Infected

Day 4 New Infected Day 4 ?

Day 5?

Day of Infection Total Infected Fill in the following table of values based on the spread of the zombie virus

Day of Infection Total Infected Fill in the following table of values based on the spread of the zombie virus

Day of Infection Total Infected How long will it take for the entire city of Salisbury to be infected? Day of Infection Total Infected ,000 21,500 32,000 42,500 53,000 Virus A Virus B Population of Salisbury, MD 30,484

How long will it take for the entire city of Salisbury to be infected? Create a graph that compares virus A to virus B. Create a graph that compares virus A to virus B.

Did you still like the virus you picked in the beginning? Explain. Did you still like the virus you picked in the beginning? Explain.

Is one virus ALWAYS worse than the other? Explain. Is one virus ALWAYS worse than the other? Explain.

VIRUS C Every 1 person can affect 3 people a day! How could you model this scenario? How much faster will people turn?

Day 0 Day 1

Day 2

Day 3 This is too hard to draw!

Day of Infection Total Infected Virus C VIRUS C Every 1 person can affect 3 people a day!

Day of Infection Total Infected ? Virus C VIRUS C Every 1 person can affect 3 people a day!

How many days until the Entire Earth is zombies? 6.8 Billion People

We need an equation to help us figure this out! Let s = starting number of infected n = number infected per day (by one zombie) d = number of days Virus C

Day of Infection Total Infected ? Virus C Does the equation work with our table?

Approximately how many days until the Entire Earth is zombies? 6.8 Billion People 6,800,000,000 People

A scientist gathered the following information before turning into a zombie. The police need you to determine what it means!

The Police need you to draw the next zones of infection!

Number of Hours RadiusArea As a scientist you need to organize your findings and present to the police!

How could you or the police use this information?
