43
What is the definition of a derived unit?
A mathematical combination of two or more units.
44
Define a "standard" as it is used in the term standard measurement.
An exact quantity that people agree to use for comparison
45
Why is it so important for industrial countries to have a standard of measurement?
Measurements can be compared to each other.
46
Why is a cubic centimeter a derived unit?
It\_s a mathematical combination of two or more units. (cm x cm x cm)
47
Why is the unit for speed, m/s, a derived unit?
It is a mathematical combination of two or more units. (meters divided by seconds)
48
Why are the points on a bar graph not connected?
There is no data between points that could be graphed.
49
Can a diagram be used as a model?
Yes, a model is used to help people better understand an idea, event, or object. A diagram serves in this function.
50
Explain how the lack of a control in an experiment impacts the experiment.
Without a control, there is no basis for comparison.
51
Abbreviation for the International System of Units
SI
52
Arrange in order from smallest to largest. (cm, km, m, mm, nm
nm, mm, cm, m, km
53
Sometimes an experiment has a whole set of hypotheses. The hypothesis that says that changing the independent varialbe will have no effect on the dependent variable is called what?
The Null Hypothesis
54
The "Null Hypothesis"
The hypothesis that their is no significant relationship between the independent and dependent variable.
55
True or False. The "Null Hypothesis" predicts that changes in the independent variable will affect the dependent variable.
False
56
The Null Hypothesis predicts what relationship between the independent and dependent variables?
No relationship at all. (Changine the independent variable has not effect on the dependent variable.)
57
You use your brain for
Inferences
58
You use your senses for
Observations
59
Which one below means the same as a constant? A Control A Controlled Variable
A Controlled Variable. A controlled variable is one of the possible variables in an experiment that you keep the same on purpose.
60
You are doing an experiment to see if ducks fly faster when listening to music with special "duck" headphones. You equip 300 ducks with these special headphones and measure their flight speed to be 43mph. You then conclude that ducks do fly faster with headphones. What is missing?
A control You would need "A Control" as a basis for comparison. In other words, you would need to measure the flight speed of a group of ducks without headphones. Then you could compare.
