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). 1. 2. 3. 4.5.

Reminders:

• Cell Analogy due in one week!

• Reading Quiz Tomorrow 9/15, pages 97-100

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:

Hyperthermia Heat receptors in the skin

Hypothalamus

StressSensors Control Center

Increased activity of sweat glands

Increased blood flow to the skin

Effectors

Effect

ed

Example: Homeostatic Regulation of Body Temperature through Negative Feedback – YOU ARE OVERHEATING!!! What happens?

Stress is reduc shutting down mechanism

Perspiration evaporates cooling

the skin

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
