using a web)
1. Setting the stage. On the board write down the two
leading questions from the previous day that the lesson
ended with: 1) Why did this (epidemics) happen at this
time in history? and 2) How did this (epidemics) happen?
During this exercise students will take notes within
a web, (see Overhead 1), Reasons Diseases become Epidemic!
(Have students take notes to further explore how to
diseases becoming epidemic. The two questions triggered
by lesson 1 are not sufficient to prepare them to address
how to investigate disease in history so additional
questions and their possible answers must be addressed.)
Overhead 1 and have students create the web on their
note sheets. You will help to fill it out. They must
write down notes as they are developed.
Explain that the web shows a different set of Why? and
but now introduces Where? When?
Ask students Why do diseases become epidemic? Diseases
happen for a number of reasons but they
caused as a result of a.) Human/animal contact
and b.) Poor
human hygiene habits.
Ask students How do diseases become Epidemic? Epidemics
occur because the disease
hosts to contaminate
and invade. Epidemics are facilitated through
human movement and travel. Ask students what would be
reasons for humans
to move? (Answers: Trade, wars, & city industry.)
Ask students Where do diseases become epidemic?
This occurs where people congregate or where
people and animals
congregate. Ask students: Where do people come
closely together? (Answers: In cities, during
through trade along trade routes.)
By now students should start seeing some patterns in
factors help diseases
The following question should address examples
become epidemic? Ask students to share their
ideas here. Answers should include: bad hygiene
systems, ignorance of treatment, and new
Finally, address: Who do epidemic diseases target? Pose
the question: Do diseases affect
poor, the rich, or both equally? Maybe
the distribution of
disease is based on age or gender? Write
down student ideas to what they would choose
Possible answers would be:
the poor because they can’t
afford luxuries that help hygiene,
b. the poor because they live in areas
with poor sewage systems or without running
c. the poor because they can’t afford medicines,
d. or both because diseases don’t care who they
affect so long as they have a body to live in.
e. children because they aren’t fully grown.
f. The aged because they are weaker.
The student webs should be filled out. End by noting that
all of these questions will help them answer the two
major questions: 1) Why did this (epidemics) happen
at this time in history? and 2) How did this (epidemics)
happen? The questions have not been forgotten but in
order to fully comprehend what epidemic diseases are,
a little ancient history needs to be explored.
