The degree of conformity of a measure to a standard or true value.
What is accuracy?
100
The factor in an experiment that changes as the result of a change in an independent variable.
What is dependent variable?
100
A question used to focus the purpose of s scientific investigation, and the procedures use to complete it.
What is research question?
100
She should test one independent variable at a time.
Why do you think Juanita decided that this was not the best way to figure out how to improve her glider?
100
If I put a 25 gram clip in a certain spot along the glider the it will glide further.
Juanita's hypothesis is now more focused. Restate it.
200
a decision based on investigation and evidence.
What is conclusion?
200
An experiment in which the 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
You should always test a variable at a time. I would test shortening the wingspan first for more aerodynamics and more surface area to get more lift.
If you were Juanita, which of the three variables would your test first? Why?
200
The independent variable is the 25 gram clip.
What is Juanita's independent variable?
300
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 the investigation can be replaced.
What is systematic investigation?
300
She should conduct her trials in a gym where wind remains constant.
Suggest how Juanita can keep factors such as wind speed and direction constant in her trials
300
It is the distance the glider travels.
What is Juanita's dependent variable?
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.
What is control group?
400
A variable that is isolated for study in an experiment in that the experimenter manipulates.
What is an independent variable.
400
A factor that changes in an experiment.
What is variable?
400
It is difficult because she has to test the different speeds with constant changing.
Why might it be difficult to test just one independent variable at a time? Use the example of Juanita and her glider in your answer.
400
She must watch the location of the clip to the length of the fight and record keeping will let her know which location of the clip works best.
Why must it important that Juanita write down the location of the clip and the result each time?
500
a variable that is kept the same from trial to trial.
What is controlled variable?
500
Having the ability to get similar results from multiple trials.
What is reproducible?
500
In order for Juanita to know the distances of the longest and the shortest flights. She must measure the distance of each flight and record each distance she measures.
Name two things Juanita must do to know the distances of the shortest and longest flights.
500
Her control group was the first ten flights.
Juanita has a control group. What is it?
500
Trials four and five are drastically different because the clip could have moved or the wing could of time.
Examine Juanita's data table. Find the unusual values and explain why they stand out from the others.
