HW: Research an Endocrine System Disorder and be ready to explain it
to the class tomorrow
CONTENT OBJ: SW relate parts of the brain to their function, and
differentiate between negative and positive feedback loops
LANG. OBJ: SW read articles, write CER paragraphs, talk in pairs and
listen to teacher/videos
AGENDA:
Right/Left Brain Self Assessment (15 min)

Feedback Loops (10 min)
Feedback Loop mini skits (10 min)
Right Brain/Left Brain
Self-assessment
What type of brain are you?
Were your scores very lop-sided, or fairly even?
Look at the back page. Which strategies might
apply to you?

Read story
What part of his brain was damaged?
Use only 10% of your brain?
Read handout and write CER
paragraph answering this question.
How does the brain send
signals?
Thoughts??
Signaling*
*Endocrine system: Made up of many glands
and cells that produce and release chemical
messengers into the blood
*Chemical messengers = hormones
“Raging hormones” ?
Levels change as you sexually mature, but
hormones help maintain homeostasis for people
of all ages
Hormones*
Chemical substance produced by the body that
controls the activity of cells or organs*
Blood transports hormones past every cell of the
body, but only certain “target” cells/organs can
respond
Cells must have the right receptor for that hormone*
*Receptors are proteins that fit the shape of a
specific hormone molecule
Lock & key interaction*
Example: Water shortage in the body
Hypothalamus
Sensory
neurons
Pituitary gland
Increased
sodium
Carried throughout body
More water
reabsorbed by body
kidneys
Vasopressin
Feedback Loops*
Negative feedback: systems work to shut off the
response that the body had to being out of
balance
Ex. Vasopressin (once body is back to normal
sodium levels, the hypothalamus stops releasing
vasopressin)
Positive feedback: adjusts internal conditions
towards the initial condition
Ex. blood clotting
Feedback Loop Examples
In pairs, come up with a mini skit
for each (positive & negative).
You have 7 minutes. Be prepared to share.
Homework
Research “Endocrine System Disorders”
online and choose one disorder to explain to
the class tomorrow.
Either write notes in your journal or print out
an article to help guide your explanation.
Make sure to reference which part of the
endocrine system is not properly functioning.
