Science is a way of knowing...
Science is based on... Science is... |
Science is a way of knowing about the natural world.
Science is based on a body of facts. Science is experimental, repeatable by others, and is subject to change. |
|
History is...
|
History is document-based knowledge about the past. History is NOT experimental.
|
|
Religion is...
|
Religion is an authority-oriented belief system. Religion is NOT experimental.
|
|
Philosophy is based on...
Philosophy is... |
Philosophy is based on ideas about how and why things are what they are.
Philosophy is NOT experimental. |
|
What stages are the process of doing science?
|
Observations
Hypothesis Experimentation Analysis of Data Reverse Hypothesis |
|
Observation
|
Studying / watching closely a specific subject in order to gain information.
|
|
Hypothesis
|
An educated guess about some phenomenon that must be testable and falsifiable.
|
|
Experimentation
|
Testing your hypothesis.
|
|
Analysis of Data
|
Will support / contradict hypothesis.
|
|
Reverse Hypothesis (or Inductive)
|
Reasoning might lead to an explanation.
|
|
What is the difference between a hypothesis and a theory?
|
A hypothesis is a widely accepted guess that is supported by evidence.
A theory is an idea or speculation that is evidence-based. |
|
What is the difference between evidence and inference?
|
Evidence is physical proof and inference is simply a conclusion based on logic or little evidence.
|
|
Why can scientific hypotheses never be proven?
|
You cannot test every instance of a hypothesis.
|
|
What is the difference between precision and accuracy?
|
Precision is reliable and consistent measurement. Accuracy is being correct.
|
|
Independent Variable
|
What the experimenter changes.
|
|
Dependent Variable
|
Factor which the experimenter measures because they think it is affected by the I.V. (they cannot change the the D.V.)
|
|
Constants
|
Controllable variables that are kept the same.
|
|
Level of Treatment
|
Changes or variations in the amount of the I.V.
|
|
Repeated Trials
|
The repeating of an experiment many times to achieve very accurate data.
|
|
Theory
|
An explanation might come from reasoning and logic.
|
|
Control
|
Comparison group that does not change the I.V.
|
|
What is a good number of repeated trials to have?
|
Five.
|
|
What was the I.V. in the grape lab?
|
The peeled grapes.
|
|
What was the D.V. in the grape lab?
|
Whether the grapes floated or not.
|
|
Name five constants from the grape lab?
|
- The solution which the grapes are in.
- The number of grapes. - Size and type of cup. - Temperature of room. - Type of grape. |
|
What was the control group in the grape lab?
(for level of treatment) |
The unpeeled grapes.
|
|
What was the experimental group in the grape lab?
(for level of treatment) |
The peeled grapes.
|
|
What should a good title look like?
|
The effect of _______ (the I.V.) on ________ (D.V.)
(but for grape lab: The Effect of Sprite on Peeled and Unpeeled Grapes) |
|
What is a good hypothesis for the grape lab?
|
The carbonation will cause the unpeeled grapes to float and the peeled grapes will absorb the solution and sink.
