Variables
The variable that the scientist is changing
WHICH CHARACTERISTIC OF LIFE:
Over time species change because their environment changes
Evolutioin
What is the largest level of organization?
Biosphere
Define Homeostasis
Maintaining a stable environment
The variable that is being measured
Dependent Variable
A cat having kittens represents which characteristic of life?
Reproduction
What is the smallest unit of life?
Cell
What are the three parts to a feedback loop?
-Stimulus
-Sensor
-Response
A group that is used for comparison in an experiment can also be the group that is left alone or considered 'normal'.
The Control Group
Which characteristic of life are feedback loops most related to?
Homeostasis
Heart, Lungs, Stomach for example are all included in which level of organization?
Organ
If someone has high blood sugar, explain the feedback loop that is associated with this.
-Stimuli
-Sensor
-Response
- High blood sugar will send a stimulus to the brain
- The pancreas releases insulin
- The blood sugar will rise to normal
Something that remains the same throughout the entire experiment for all groups.
Which characteristic of life is responsible for digesting your food?
Metabolism
A group of organs working together for a specific function. EXAMPLE: Respiratory System
Organ System
Why are feedback loops important?
To maintain homeostasis so there is no cell death or tissue damage
Sing the song for IV / DV / Hypothesis as a group!
Independent variable, I independently change. Dependent variable, thats the one we measure.
What is a hypothesis? IF...THEN...BECAUSE !
Name the 8 characteristics of life

3. Metabolism
4. Evolution within a species
5. Homeostasis
6. Growth & Development
7. Response
8. Genetic Information
All the catfish in the Delaware River are an example of which level of organization?
Population
An organism’s reaction to something in its environment is called
a stimuli or response to stimuli
