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 a dependent variable
100
a question used to focus the purpose of a scientific investigation and the procedures used to complete it
What is a research question
100
Why do you think Jauntia decided that this was not the best way to figure out how to improve her glider.
What if she should test one independent variable at a time.
100
What is Juanita's independent variable?
What is the independent variable is the 25 gram clip.
200
a controlled variable in an experiment that is kept the same from trial to trial.
What is a constant
200
an experiment in which one independent variable is tested by keeping all other independent variables the same
What is a fair test
200
the numbers of observation or data
What is a sample size
200
If you were Jaunita, which of the three variable would ypu test first? Why?
What is you should always test one variable at a time. I would test shortening the wind span first for more aerodynamics and more surface to get lift.
200
what is Juanita's dependent variable
What is the dependent variable is the distance the glider glides
300
a decision based on investigation and evidence.
What is conclusion
300
an idea that can be tested by a scientific investigation
What is a hypothesis
300
an investigation in which all variables are identified and recorded so that the investigation can be repeated
What is systematic investigation
300
Suggest how Juanita can keep factors such as wind speed and direction constant in her trials
what is she should conduct her trials in a gym where wind remains constant
300
Juanita's friend Charelle says that Juanita is working too hard. Charelle says that each time Juanita moves the clip she should throw the glider only once. Will this method produce a sufficient sample size? Explain your answer
What is more traits are necessary for Juanita to determine the best place to add weight to the glider
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 a control group
400
a variable that is isolated for study in an experiment and that the experimenter manipulates.
What is an independent variable
400
a factor that changes the experiment
What is a variable
400
Juanita already has a control group. What is it?
What is her control group was the first ten test flights and the wind speed.
400
Why is it important that Juanita write down the location of the clip and the result each time?
What is she must match the location of the clip to the length the flight and record keeping will let her know which location of the clip works best
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
name two thing Juantia must do to know to distances of of the shortest and longest flights.
What is in order for Jauntia to know the distances between the longest and shortest flights she must measure the distances of each flight and record each each distance.
500
Juanita's hypothesis is now more focused. Restate it.
What is if I put 25 grams in a certain spot on the glider then it will glide further.
500
Examine Juanita's data table find the unusual value and explain why they stand out from the others
What is trials four and five are drastically different because the clip could have moved or the wing could of broke.
