The group that is exposed to the independent variable
What is the experimental group
100
The basic structure of all living things
What are cells
100
Scientists use this system of measurements so that data from all over the world can be compared.
What is the International System of Units (or SI units)
100
These types of observations and data do not include numbers
What are qualitative
200
All experiments should be done in such a way as to be repeatable by other scientists. The process of repeating another scientist's work is this
What is peer review
200
The one variable that changes during an experiment
What is the independent variable
200
The process of maintaining a stable environment in response to internal and external stimuli
Homeostasis
200
The purpose for performing an experiment several times and/or running multiple trials
What is to obtain consistent results, to have a larger data pool, to verify or eliminate unusual or unexpected results.
200
This is the SI unit of measurement for mass
What is gram or kilogram
300
Scientists use these to gather data about a proposed hypothesis
What are experiments or detailed observations
300
All variables that remain the same in all groups and throughout the experiment
What are constants
300
Growth in living things happens by one of these two processes (both are generally occurring constantly in large organisms)
What is cell enlargement and cell division
300
A description of a consistent occurrence or behavior in nature
What is scientific law
300
These practices resemble science, but cannot be supported by scientific research or experimentation
What is pseudoscience
400
After data has been collected and analyzed, a scientists either supports or challenges his/her hypothesis by forming one of these
What is a conclusion
400
The variable that is measured or observed as data during an experiment
What is the dependent variable
400
A rat scurries past a python and the python strikes at the rodent. This is an example of
What is stimulus and response
400
Combining what was known with what has been recently learned in order to come to a logical conclusion
(Hint: what do we call that conclusion?)
What is inferring (or an inference)
400
The white hair on a polar bear and the ability of a chameleon to change colors depending upon its environment are examples of this characteristic of living things
What is adaptation (or the ability to adapt)
500
All data must be review for detail, to ensure accuracy, and to check for errors. This process is called
What is analysis
500
Group that is used only for comparison
What is the control group

Name the characteristics that all living things share (there are 8)
Made of cells (organization), contains genetic information (DNA), grows & develops, reproduces, responds to stimuli
uses energy, maintains homeostasis, adapts, and evolves
500
Every scientist planning a controversial experiment must consider these, which can be both personal and societal
What are ethics
