Scientific Method Flashcards
What is the Scientific Method?
- to showcase the different ___ of ____ based on different ____
- a ____ that contains ____ (#) steps
- done through the formulation of a _____ on the basis of f____ f____
- to showcase the different ways of observation based on different scientists
- a cycle that contains 7 steps
- done through the formulation of a hypothesis on the basis of few facts
1st step (3 bullet points)
- o_____
- r_____
- know what _____ to ____
“Define the problem”
- observation
- realization
- know what questions to ask
2nd step (2 bullet points)
- state ____ and ____
- know what _____ is/will be ____
“Statement of the problem”
- state clearly and concisely
- know what problem is/will be solved
3rd step (1 bullet points)
- c___ and i____ the “____” from p______ ______
“Collect information”
- collect and identify facts from previous studies
4th step (2 bullet points)
- e_____ g____
- to find the r_____ for the problem
“Formulate hypothesis”
- educated guess
- to find the reason for the problem
5th step (2 bullet points)
- to obtain c___ and r___ data through _____
- “_____ EXPERIMENT” - most widely used design in p___, c____ and n____ sciences
*all possible factors that have bearing on the problem are not held/held constant— and manipulated one at a time in experiments
“Test hypothesis”
- to obtain clear and repeatable data through experimentation
- “CONTROLLED EXPERIMENT” - most widely used design in physics, chemistry, and natural sciences
*all possible factors that have bearing on the problem are held constant— and manipulated one at a time in experiments
6th step (2 bullet points)
- g____ and o____ all data into correct g____, c____ or t____
- use appropriate s____ tools
“Correlation and interpretation of data”
- gather and organize all data into correct graphs, charts, or tools
- use appropriate statistical tools
7th step
Hypotheses can be
- correct -> ____
- not supported by evidence -> _____ *
- This leads to more _____ asked and a new _____ formulated and tested.
*Thus, it becomes a ____ from:
-> ___ (o______ -> t______)
-> ___ (t___ of why it went wrong -> o__)
-> ___ (o______ -> t______ again)
“Drawing conclusions”
Hypotheses can be
- correct -> accepted
- not supported by evidence -> modified *
- This leads to more questions asked and a new hypothesis formulated and tested.
*Thus, it becomes a cycle from:
-> inductive (observations -> theory)
-> deductive (theory of why it went wrong -> observations again)
-> inductive (observations -> theory)
