• Paid Travel opportunities
• Engaging classes ()
• School activities match your interest

19. Populations
Population: organisms in the same species and live in the
same geographical area (close enough to interbreed)
Some factors that ecologists consider when they study
populations:
Geographical range: the size of the area the
population lives in
Density: how close together organisms in a
population live together
Age Structure: The percentage of people in different
age groups
Growth rate: how fast or slow is the population size
increasing
20. Food for Thought
On the issue of human overpopulation…
Do you think everyone should have the right to
reproduce? Even if they don’t have the financial,
physical, or social ability to provide for their offspring?
What if this reproduction rights had an effect on how
much taxes you have to pay? Etc. Should everyone
still have the right to reproduce?
22. Eugenics
• the social movement claiming to improve the
genetic features of human populations through
selective breeding and sterilization
23.
24. Eugenics in US Law
• Indiana became the first state to enact sterilization
legislation in 1907, followed closely by Washington and
California in 1909.
• 1927 Supreme Court case Buck v. Bell which legitimized
the forced sterilization of patients at a Virginia home for
the mentally retarded.
• An IQ of 70 or lower meant sterilization was appropriate
in North Carolina.
• The American Breeder’s Association was the first eugenic
body in the U.S. The ABA was formed to “investigate and
report on heredity in the human race, and emphasize
the value of superior blood and the menace to society
of inferior blood.” Membership included Alexander
Graham Bell, Stanford president David Starr Jordan and
Luther Burbank.
25. Eugenics in US Politics
• Margret Sanger founder of planned parenthood:
Margaret Sanger saw birth control as a means to
prevent unwanted children from being born into a
disadvantaged life, and incorporated the
language of eugenics to advance the movement
26. Eugenics in California
• The state of California was at the vanguard of the
American eugenics movement, performing about
20,000 sterilizations or one third of the 60,000
nationwide from 1909 up until the 1960s.
• Almost 19 million people attended the Panama-
Pacific International Exposition in San Francisco.
o Conference for 10 months to address stopping disease and inferior
characteristics through eugenics
27. Why and Who to Sterilize
• Men and women were compulsorily sterilized for
different reasons. Men were sterilized to treat their
aggression and to eliminate their criminal behavior,
while women were sterilized to control the results of
their sexuality (prostitution)
28. How to Sterilize and
Euthanize
• A mental institution in Lincoln, Illinois fed its incoming
patients milk infected with tuberculosis (reasoning
that genetically fit individuals would be resistant),
resulting in 30-40% annual death rates.
• Unknown “Cure”
• Medical Neglect
29. Eugenics Cali to Germany
• California eugenicists began producing literature
promoting eugenics and sterilization and sending it
overseas to German scientists and medical
professionals. By 1933, California had subjected
more people to forceful sterilization than all other
U.S. states combined. The forced sterilization
program engineered by the Nazis was partly
inspired by California's
31. Eugenics Cali to Germany
• Upon returning from Germany in 1934, where more
than 5,000 people per month were being forcibly
sterilized, the California eugenics leader C. M.
Goethe bragged to a colleague:
• "You will be interested to know that your work has
played a powerful part in shaping the opinions of
the group of intellectuals who are behind Hitler in
this epoch-making program. Everywhere I sensed
that their opinions have been tremendously
stimulated by American thought . . . I want you, my
dear friend, to carry this thought with you for the rest
of your life, that you have really jolted into action a
great government of 60 million people."
32. End-ish of Eugenics
A few years after end of WWII and Nazi Germany
1968-1969 (End of WWII - 1945)
- Feminist Movement
33. Good Afternoon!
Warm up:
1. Warm up questions
How engaged did you feel yesterday? Why?
On a scale of 0-100. (0 being unproductive and 100 being
highly productive) What would you rate yourself?
2. Turn in your STAR Packet. Make a neat pile on the table
in front of the fridge.
Agenda:
P1 – Sex in a Cup (HIV/AIDs Transmission)
P2 – Guest Speaker
P3 – Guest Speaker
P4 – Sex in a Cup (HIV/AIDs Transmission)
34. HIV/AIDs Activity
Title: HIV/AIDs – Sex in a Cup
Purpose: To demonstrate how HIV can spread and
how pathologists locate patient zero (the patient that
first contracted the disease)
Method:
1. Get a cup filled with fluids and the post-it attached
to it. (Do not sniff or drink your fluid cup. If fluids get
in contact with skin, rinse immediately with cold
water)
35. HIV/AIDs Activity
Method:
2. Read the post-it privately to yourself. The post-it will
determine your behavior in trial 1. Keep it a secret.
3. When you exchange body fluids, pour your fluids in their
cup and take back and equal amount of fluid you gave
away to your partner.
4. You must ask permission to exchange fluids and you may
not tell the person your role.
5. Keep track of who you exchanged body fluids with in the
results table
6. Only exchange fluids if you role allows you too.
7. After exchanging fluids for 5 times you will be
administered an AIDs test
