Scientific Method
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
what is a factor, feature, or quantity that can be changed or measured during an experiment?
Variable
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?
Conclusion/Sharing your results
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
The group that remains unchanged, used as the comparison in an experiment,
Control
True or False: It is important to conduct multiple trials in an experiment.
Gathering information by using your senses
Observation
In what step of the scientific method do we want to use graphs?
Analyze data
What is the second step of the scientific method?
Doing research on your topic
True or False: An experiment is successful when new information is learned, even if the original hypothesis is not supported by the results of the experiment.
True
When a scientist shares their findings with other scientists, what step of the scientific method are they completing?
Sharing Results
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
A scientist who wants to study the affects of fertilizer on plants sets up an experiment. Plant A gets no fertilizer, Plant B gets 5 mg. of fertilizer each day, and Plant C gets 10 mg of fertilizer each day. Which plant is the control group?
Plant A
What step of the scientific method has us making sense of the data, looking for patterns, finding trends, ect.
Analyze data
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
A scientist wants to test a pill that lowers a persons anxiety levels. Group A receives this new pill, while Group B receives a sugar pill so that neither group knows if they are receiving the new pill. Group A reports 50% of its members having less anxiety after the experiment, while Group B reported 12% of their group members having less anxiety. Why might Group B have members who reported feelings of lower anxiety?
