Museum DefensesPhysical Barriers of

the Museum that help keep invaders

out

Technological Systems that help identify

invaders

Museum personnel that

help identify and deal with invaders

Devices that help spread the word

of invaders

Non Museum personnel that deal

with invaders

Question 1

1. What is the purpose of the physical barriers in a museum? Are they meant to keep just invaders out? All people out? What are the advantages to this system?

Question 2

What are the different roles of museum personnel? Are they meant to indiscriminately keep people out? Or just invaders? How do they identify potential invaders?

Question 3

What are some ways that the museum personnel communicate with each other?

Question 4

Go through the 13 cards of our immune defenses. Think about how each one is analogous to a part of the museum security system. Decide where each card would best be analogous by writing its defense in the chart. ex.) Skin is analogous to a physical barrier of museum

Question 5

How did the invaders try to circumvent the various parts of the museum security system? Name two ways that body invaders circumvent the immune systems? What are similarities and differences between the two situations?
