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 are charts used for
to collect Data
supplies and equipment used during an experiment
Materials
Equal; Both items have the same value
Equivalent
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.
True
Gathering information by using your senses
Observation
the act of gathering or grouping something together
Collection
a scientific procedure to make a discovery
Experiment
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
A scientist wants to test how fertilizer affects plant growth. The plants that do not receive fertilizer are part of this group.
What is the control group?
What is the second step of the scientific method?
Doing research on your topic
using the scientific method to answer a question, using observation and experimentation
Investigate
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/Ask
Research
Hypothesize
Experiment
Analyze/Test Hypothesis
Conclude
In what step of the scientific method do we want to use graphs?
Analyze data
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
A hypothesis that has been tested many times and is widely accepted by scientists is called this.
