What is NOT included in the scientific inquiry process? (Choose ALL that apply)
bias
prejudice
research
stating results
making a prediction
Where would Chemistry most likely be studied?
in the field
in a lab
in your garage
anywhere
Where would Geology most likely be studied
in a lab
in the field
in a garage
anywhere
What methods would be used to investigate in different fields of science? (Choose ALL that apply)
making direct observations
recording empirical evidence
selecting the results that support your hypothesis
using bias to address your research
Which of the following are ways to collect empirical evidence? (Choose ALL that apply)
collecting qualitative data
collecting quantitative data
collecting assumed data
collecting bias data
What steps should a scientist first take if a hypothesis is NOT supported?
modify the original hypothesis
revise the results to fit the hypothesis
eliminate the data that doesn't support the hypothesis
discard the experiment and start all over
Choose the example that best represents an independent variable.
The scientist is changing the amount of water given to plants.
The scientists measures the height of the plant to determine which one is taller.
The scientist doesn't give any water to one of the plants to determine how the plant is affected by the lack of water.
The scientist makes many changes to see which change affects the growth of the plant.

Choose the example that best represents an control group.
The scientist is changing the amount of water given to plants.
The scientists measures the height of the plant to determine which one is taller.
The scientist doesn't give any water to one of the plants to compare the results of the other plant growth to the plant the receives no water at all.
The scientist makes many changes to see which change affects the growth of the plant.
Which statement best represents repetition?
a scientist performs their experiment several times to ensure the accuracy of their results.
other scientists repeat your experiment to ensure the accuracy of your results.
you repeat another scientist's experiment to ensure the accuracy of their results.
a scientist performs another scientist's experiment several times to ensure the accuracy of results.
Which statement best represents replication in an experiment?
A scientist performs the same exact experiment as another scientist to ensure the accuracy of the initial scientists' results.
A scientist performs the same exact experiment as they did before to ensure the accuracy of the initial findings.
A scientist replicates an experiment several times in an experiment by running 3-5 trials.
An experiment is replicated when a scientist performs the same experiment several times to calculate an average of their overall data collection
Why do scientists replicate experiments?
to ensure accuracy and reliability.
to ensure averages and replication
to ensure a scientists' ability to collect data correctly
to ensure an accurate and readable hypothesis
What is necessary for experimental results to be acknowledged by they scientific community? (Choose ALL that apply)
the experiment must be repeated by yourself multiple times.
the experiment must be conducted by other scientists.
the experimental findings must be discussed and debated by a panel of scientists.
the experiment must be done in a lab setting
How do scientists communicate experimental results? (Choose ALL that apply)
writing science journals
speaking at science conferences
exchanging information on the internet
sharing information about recent findings with their friends
How can debate among scientists benefit the scientific community? (Choose ALL that apply)
Modifications of science ideas
New technological developments
New science theories and/or laws being developed.
Ensures separation among scientists in the community
What statement best models a scientific theory? (Choose ALL that apply)
all living things are made of cells
Energy is neither created nor destroyed.
Earth's outer shell is divided into pieces known as tectonic plates
all things are made of matter.
What statement best models a scientific law? (Choose ALL that apply)
all living things are made of cells
Energy is neither created nor destroyed.
Earth's outer shell is divided into pieces known as tectonic plates
all things are made of matter.
What are the benefits of using scientific models? (Choose ALL that apply)
models allow us to study processes too big for real life
models allow us to study processes too small for real life
models are so exact that we can assume the results we gather from using them are accurate.
the scalar size of models is not necessary because scientists are trained to exact the difference.
Some limitations of using the scientific method are, (Choose ALL that apply).
models are not always exactly to scale
models are not always accurate
models may change when new findings are made
models may not be exact representations of what they are trying to show.
