Warm Up (Silent) 9/14
Track a protein through a cell, from where the
information is stored to make the protein to where the
protein leaves a cell. Include each organelle and the
function of the organelle.
(Hint: One organelle is used twice).

Homeostasis
A condition in which the internal environment
of the body remains relatively constant despite
changes in the external environment.
What conditions does your body have to keep in
equilibrium? (temperature… what else?)
Cupples Activity
• Read the short intro and then fill out
the ‘Definitions’ and ‘Driving
Homeostasis’ sections
Learning Target: Develop and use a model to
illustrate the hierarchical organization of interacting
systems that provide specific functions within
multicellular organisms.
Function: Maintaining Homeostasis
Topic: The control of Blood Oxygen/Carbon
Dioxide content during and after exercise
Model: Concept Map
Essential Question:
• How and why does heart rate increase with
exercise?
– Class brainstorm:
• Tell me what you know about the relationship between
heart rate and exercise
– We will concept map this later
What is a Concept Map?
• A web of boxed terms/concepts connected by
arrows
• Arrows are labeled with words that describe
the connection between boxes
• Boxes should be connected so that the map
can be followed in a logical way to organize
ideas
• Here are examples of good concept maps:
Example: Homeostatic Regulation of Body Temperature through
Negative Feedback – YOU ARE OVERHEATING!!! What happens?
Hyperthermia
Stress
Stress is reduced
shutting down
mechanism
Perspiration
evaporates cooling
the skin
Effect
Heat receptors in
the skin
Hypothalamus
Control Center
Sensors
Increased activity
of sweat glands
Increased blood
flow to the skin
Effectors
Class Concept Map:
• Let’s generate a list of everything we know
about heart rate and exercise and put it on a
class concept map
• Think about how we maintain our
homeostasis
Task: Make a concept map on diabetes and
how blood sugar is regulated in your body
• Use our class concept map as a starting point
• You will read the article “How Diabetes Works”
independently
• Develop a list of key concepts and words that should be
included on your map Notes Section
