SM 1
A series of steps designed to help you solve problems and answer questions
A) scientific method
B) experiment
C) hypothesis
D) observation
A) scientific method
any factor, trait, or condition that can exist in differing amounts or types
Variables
What is the 1st step of the scientific method?
Make an Observation
The information (evidence) gathered from observations and experimentation is called
Data
Scientists are the only individuals who use the scientific method True or False
False - WE ALL USE IT
What is the last step of the scientific method?
Conclude
What is a hypothesis?
An educated guess or prediction of what you think the outcome will be
What 2 words should always be in your hypothesis statement?
If, Then
What type of data is Numerical Data and Measurements
Quantitative
What type of data is Descriptive or Physical Data
Qualitative
unchanged, used as the comparison in an experiment
Control
statement that answers the question/ statement of your understanding of the results
Claim
Gathering information by using your senses
Observation
A graph that shows data over time
line graph
A graph that shows percentages/parts of a whole
circle graph or pie graph
Data, details, and facts that support your claim
Evidence
graph for comparing data collected by counting
bar graph
the variable you manipulate, control, or vary in an experimental study to explore its effects
A. | Dependent |
B. | Independent |
C. | Control |
D. | Uncontrolled |
B- Independent
evidence or arguments that are used to contradict, disprove, or counter the claim
Rebuttal
Making sense of the data, looking for patterns, finding trends, ect.
Analyze
A scientist conducted an experiment to determine how the amount of salt in a body of water affects the plants that can live in the water. In this experiment the independent variable is
A) the types of plants
B) the amount of salt in the water
the amount of salt in the water
What are the steps to the scientific method?
Observation
Question
Research
Hypothesize
Experiment
Analyze
Conclude
what changes as a result of the independent variable manipulation in experiments (what we measure)
dependent variable.
Different preservatives were tried in foods to determine which best restricted the growth of molds. What is the dependent variable?
Growth of Mold
