Cards in this deck (21)
- 1What is Science?knowledge covering general truths tested through the scientific method
- 2How does science operate?By using the scientific method!
- 3What are the steps of the scientific method?1. observation
2. hypthothesis
3. make a prediction
4. test the hypothesis
5. accept or reject the hypothesis - 4Example of Initial Observationthe student is always sleepy in class
- 5Example cont.: HypthothesisThe student is always sleepy in class because she is not getting enough hours of sleep at night
- 6Example cont.: Make a predictionIf the student sleeps more at night, then she will not be sleepy in class anymore
- 7Example cont. : test the predictionhave the student sleep more at night and see if she is no longer sleepy in class
- 8Example cont.: Accept or reject the hypothesisthe student is still sleepy in class, so reject the hypothesis (There is some other reason why the student is sleepy in class)
- 9What are the different "types" of science?Pseudo science and Science?
- 10What are some key characteristics of science?-science challenges its claims and looks for evidence that might make those claims false.
-its testable - 11How does science differ from religion?religion doesn't make any testable predictions
- 12HypothesisA statement that's based on an observation that should make a prediction that can be tested & therefore be rejected or accepted.
- 13TheoryA set of ideas that explain many observations.
A theory incorporates several hypotheses that have been tested and accepted. - 14Lawis a simple statement that explains all occurrences of a particular phenomenon. There are usually no exceptions to a law.

- 17What is the power of a theory and a hypothesis1. its ability to explain a large variety of phenomena.
2. its ability to make many (testable predictions) - 18Why is the theory of Plate Tectonics a powerful one?it explains why we have mountains, volcanoes, earthquakes, and many other physical features and phenomena at various locations on Earth
&
it makes a lot of predictions! - 19What do scientists use in order to avoid making subjective judgements when making measurements?instruments
- 20What's a difficult step in the scientific method?making sure to analyze the data with an open mind and not make implicit assumptions
