Nature of Science
What is the field of imitation science?
Pseudoscience
The variable being manipulated by the scientist?
Independent variable
A signal from an organisms environment that causes a change
Stimulus (stimuli)
Homer notices that his shower is covered in a strange green slime. His friend Barney tells him that coconut juice will get rid of the green slime. Homer decides to check this out by spraying half of the shower with coconut juice. He sprays the other half of the shower with water. After 3 days of "treatment" there is no change in the appearance of the green slime on either side of the shower.
What is the hypothesis?
IF Homer use coconut juice on the slime THEN it will be cleaned.
An example of pseudoscience?
Astrology, Scientific Racism, Feng Shui, Hyponosis, Conversion Therapy
An explanation of a natural phenomenon supported by many observations and experiments
Theory
Variable that changes in response to the independent variable?
Dependent variable
This is the term used to explain how an organism maintains a stable internal environment
Homeostasis
Homer notices that his shower is covered in a strange green slime. His friend Barney tells him that coconut juice will get rid of the green slime. Homer decides to check this out by spraying half of the shower with coconut juice. He sprays the other half of the shower with water. After 3 days of "treatment" there is no change in the appearance of the green slime on either side of the shower.
What is the control?
The half of the shower sprayed with water.

Characteristic of life wherein an organism increases in size or # of cells and/or undergoes natural changes over its lifetime?
Growth and development
Homer notices that his shower is covered in a strange green slime. His friend Barney tells him that coconut juice will get rid of the green slime. Homer decides to check this out by spraying half of the shower with coconut juice. He sprays the other half of the shower with water. After 3 days of "treatment" there is no change in the appearance of the green slime on either side of the shower.

Metabolism
Homer notices that his shower is covered in a strange green slime. His friend Barney tells him that coconut juice will get rid of the green slime. Homer decides to check this out by spraying half of the shower with coconut juice. He sprays the other half of the shower with water. After 3 days of "treatment" there is no change in the appearance of the green slime on either side of the shower.
What is the dependent variable?
The level of cleanliness
A change in an organism's ability over time?
Development
A process by which the procedures used during an experiment and the results are evaluated by other scientists who are in the same field or who are conducting similar research?
Peer review

Inherited adaptations that lead to species long term survival?
Evolution
Homer notices that his shower is covered in a strange green slime. His friend Barney tells him that coconut juice will get rid of the green slime. Homer decides to check this out by spraying half of the shower with coconut juice. He sprays the other half of the shower with water. After 3 days of "treatment" there is no change in the appearance of the green slime on either side of the shower.
What is the conclusion?
Hypothesis was REFUTED (NOT supported)...no change in the appearance of the green slime on either side of the shower.
