100
In a controlled experiment, there is only one factor that can change at a time. This tested factor that might affect the outcome of the experiment is called this.
What is the independent variable?
100
These five steps are found in the scientific method.
What are ask a question, form a hypothesis, collect the data, analyze the data and report conclusions?
100
Information gained from observations.
What is data?
100
A pie chart is most appropriate for showing this type of relationship.
What is the proportion of the parts to the whole?
100
The symbol for the base unit "liters."
What is capital "L" ?
200
A second factor measured by scientists in an experiment, this factor results from changes to the independent variable.
What is the dependent variable?
200
In the first step of the scientific method, this (a direct method of gathering information in an orderly way) and this (combining what you know and what you have learned to make logical conclusions) might be made.
What are observations and inferences?
200
Biologists all use similar ones of these to gather information and to answer questions.
What are scientific methods?
200
This type of representation is used to see if there is a correlation.
What is a scatter plot?
200
M
What is "Mega" ?
300
This is the group in an experiment exposed to the factor being tested.
What is the experimental group?
300
In the second step of the scientific method, you make one of these. This is important because this is a statement showing what you want to test therefore defining how you change your variables.
What is the hypothesis?
300
When a biologist conducts one of these to test a hypothesis, he or she investigates a phenomenon in a well defined laboratory setting.
What is a controlled experiment?
300
This variable is usually plotted on the x-axis of a scatter plot.
What is the INDEPENDENT variable?
300
The prefix and base unit symbols meaning "one billion seconds."
What is " Gs " ?
400
In an experiment, this group is used for comparison.
What is the control group?
400
In the last two steps of the scientific method, biologists find themselves asking themselves about this. Often, the investigation must be repeated many times to obtain consistent results. Later, after being carefully examined by reviewers, they can publish their findings in a journal.
Possible answers: What is "Has my hypothesis been supported?" What is "Is more data needed?" What is "Are different procedures needed?" (Any question regarding whether or not they have accurate findings.)
400
This is a logo designed to alert you about a specific danger.
What is a safety symbol?
400
This type of representation is used to show grouped data.
What is a bar chart?
400
The symbol for the prefix that means "one billionth" of any base unit.
What is " n " ? (name = nano)
500
In an experiment, these are factors that remain fixed while the independent and dependent variables change.
What are the controlled variables?
500
These are the four branches of the third step in the scientific method. In other words, these are the four things biologists will set up while conducting an experiment during the fourth step of the scientific method.
What are controlled experiments, experimental designs, data gathering, and investigations?
500
This is the occurrence of accidental or unexpected but fortunate results.
What is serendipity?
