Questions
100
the degree of conformity of a measure to a standard or a true value.
What is accuracy?
100
the factor in an experiment that changes as a result of a change in an independent variable.
What is dependent variable
100
a question used to focus the purpose of a scientific investigation and the procedures used to complete it.
What is research question?
100
Other scientists carry out the same experiment to see if they get the same result.
What is how does the scientific community confirm that a scientist's work is valid?
100
Fair test makes a change in just one independent variable at a time to see how it effects the dependent variable. Many variables are at work when conducting an experiments it's hard to name them all.
What is Paco's hypothesis, independent variable, dependent variable, and constant in his experiment?
200
A decision based on investigation and evidence
What is conclusion?
200
an experiment in which one independent variable is tested by keeping all other independent variables the same.
What is fair test
200
the number of observations or data.
What is sample size?
200
4-2-1-3
What is in which order should Dietrich conduct these steps?
200
In order for Juanita to know the distances the longest and shortest she must measure the distance of each flight, and record each distance she measures.
Name two things Juanita must do to know the distance of the shortest and longest flights.
300
a controlled variable in an experiment that is kept the same from trial to trial.
What is constant
300
an idea that can be tested by a scientific investigation.
What is hypothesis?
300
an investigation in which all variables are identified and recorded so that the investigation can be repeated
What is systematic investigation?
300
The season of the year
What is what was the independent variable in Jack's study?
300
she should test one independent variable at a time.
If you were Juanita which of the three variables would you test first?
400
a set of observations made in an experiment, in which the independent variables are not changed, to be sure that the dependent variable remains the same also.
What is control group?
400
a variable that is isolated for study in an experiment in that experimenter manipulates.
What is independent variable?
400
a factor that changes in an experiment.
What is variable?
400
Experimental results must be reproducible to be accepted as valid.
What is what do these events say about the process of scientific inquiry?
400
She should conduct her trials in the gym where wind stays the same.
Suggest how Juanita can keep factors such as wind speed and direction constant in her trials?
500
a variable that is kept the same from trial to trial
What is control variable?
500
having the ablity to get similar results from multiple trials
What is reproducible?
500
test tube temperature and reaction duration
What is parameters were held constant in Annessa's experiment?
500
The sample size was much too small.
What is what error did Lewis make in his investigation?
500
Ten test flights was her control group.
Juanita already has her control group. What is it?
