Do you think vampires exist?

If its possible, I wonder

• How long it would take vampires to take over this
  school?
  

How long before they would take over your
town?

How long it would take for vampires to take
over the USA?

Your Mission

• Your mission...should you choose to accept itis
  to use Excel to find out how long it would take
  for vampires to take over this school, this town,
  and the USA.
• You may work individually or in partners of no
  more than 2.
  
• If you need help, ask a neighbor or the teacher.

The Details

• The first day, day 0, youll start with 1 vampire
  and no one bitten.
  
• Each day after that each vampire will bite 1
  person.
  
• Use Excel to find out the answers to the three
  questions
  
• How long will it take them to take over the
  school?
  
• The town?
• The USA?

The Setup

Any short cuts?

• Are there any short cuts you can use in Excel to
  complete the chart faster?
  
• Review your notes and talk with your neighbors.

What does it look like?

• Graph your chart from day zero until the day
  vampires have taken over the school.
  
• What do you see?
• Can you describe what kind of slope that is?
• Why does it look like this?
• Answer these questions and turn in your paper,
  with the graphs, at the end of class.
  
• If youre working in a group of 2, one sheet with
  both names written at the top is acceptable.

  the day vampires have taken over the town? The
  USA?

  a separate sheet of paper that you will hand in
  with your graphs for our next class.
