Emergent Property - answer✔A property that a complex system has but the individual members

of the system do not.

Sum is greater than the parts

Ex: Salt (NaCl, not salty individually, but together they are) Skin cells




It's the property where living things become more and more complex as it goes from cellular

level (exp humans are made of cells) to organ system (exp humans are made of organ system

composed of millions of cells).

Respond to stimuli

Homeostatic

Grow and Develop

Have the capacity to adapt


Homeostasis - answer✔the ability of an organism to maintain its internal environment, despite

changes to its internal or external environment


Law - answer✔Describes a pattern in nature, the "WHAT"


Ex: The law of evolution, Law of gravity


Theory - answer✔Explanation to why a pattern exist, the "WHY" or "HOW"


What does a theory do? - answer✔1) explains a natural phenomenon- how nature works


2) predicts future occurrences or observations of the same kind

3) can be tested through experiment or otherwise verified through empirical observation

4) is supported by a vast body of reliable evidence


Difference between a Law and Theory? - answer✔theory- explains natural phenomena: how

nature works

law- describes natural phenomena: how it works under certain conditions


Null Hypothesis - answer✔It is a statement about the population that either is believed to be true

or is used to put forth an argument unless it can be shown to be incorrect beyond a reasonable

doubt.

Alternative hypothesis - answer✔It is a claim about the population that is contradictory to the

Null and what we conclude when we reject Null.


inductive reasoning - answer✔makes generalizations based on collecting and analyzing a large

number of specific observations.




Specific Details, Theory,

Observation of pattern, General Truth




Ex: Every dog I have ever seen has 4 legs; Dogs are 4 legged animals.


Deductive Reasoning - answer✔Flows from general premises to predicted and specific results.




reasoning in which a conclusion is reached by stating a general principle and then applying that

principle to a specific case




Ex: The sun rises every morning, therefor the sun will rise on Tuesday


Variables - answer✔anything you can change or control in an experiment.

Ex: temperature, duration of the experiment, composition of a material, amount of light, etc.


Three different kinds of variables - answer✔Controlled Variable


Independent variable

Dependent variable


Independent/Experimental Variable - answer✔the one factor that you are changing




Ex: If you are trying to determine whether heating water allows you to dissolve more sugar in the

water then your independent variable is the temperature of the water. This is the variable you are

purposely controlling.


dependent/Responding variable - answer✔variable you observe, to see whether it is affected by

your independent variable.




Ex: In the example where you are heating water to see if this affects the amount of sugar you can

dissolve, the mass or volume of sugar (whichever you choose to measure) would be your

dependent variable


confounding variable - answer✔an extraneous variable whose presence affects the variables

being studied so that the results you get do not reflect the actual relationship between the

variables under investigation
