Chapter 1: Measurement & Scientific Method KEY
1. What is SCIENCE?
The knowledge about the nature of things that is obtained by
doing experiments.
2. What is technology?
The application of science to make new products or tools
people can use.
3. What is the scientific
method
4. Steps of the scientific
method
General way of organizing your thinking about questions
5. What is the difference
between a model and
an experimental
question?
6. How is a law different
from a theory?
A model is a representation of an object that you can study to
better understand or see something. An experimental question
is a problem you can have several different hypotheses about
to test.
A scientific law has been proven by repeated experiments to be
true. Laws allow us to make predictions about how a system
will behave. A theory is always questioned and examined.
They explain observations clearly and have not been
“disproven.”
7. How is an observation
different from an
inference?
An observation is the gathering of information by using our five
senses: Sight, Smell, Hearing, Taste, Touch
1.

5.
6.
Ask a question/ identify the problem
Gather information
Form a hypothesis
Develop a procedure (test the hypothesis)
Analyze results
Come up with a conclusion (is your hypothesis
accepted)
Inferences are an explanation for an observation you have
made. They are based on your past experiences and prior
knowledge.
8. Data can be qualitative
or quantitative. What
is a quantitative
observation?
Give an example of a
quantitative observation.
9. What is a qualitative
observation?
An observation that contains measurements and numbers.

10. Data is often
represented in a
graph. What type of
data is best
represented by a pie,
bar, and line graph?
11. What are 3 things
you should include
when writing a
conclusion.

12. What is the
independent/
manipulated
variable?
13. What is the
dependent/
responding variable?
14. All other variables
should stay ___.
15. How many variables
should be tested at a
time?
16. What is the control
group? Give one
example.
The independent variable is the ONE thing you purposely
manipulate in the experiment.
17. What tool and units
should be used to
measure LENGTH?
18. What is mass?
Pie Graph-show the parts of a whole
Bar Graph- compares the values of items
Line Graph- show continuous changes over time
1. Whether your data supports your hypothesis or not
2. Possible errors that may have occurred, things that may
not have gone the way you thought they would in the
experiment.
3. What you may do differently if you were to do the
experiment again.
The dependent variable is what you measure, the variable that
is responding to what you changed.
CONSTANT
ONE!
The group of subjects in your experiment that you do nothing
to- no changes for independent variable.
If you are testing how much fertilizer makes a plant grow the
best, a control group would have NO fertilizer.
Tool-ruler/ meterstick
Units:
Length of a paperclip- mm/ millimeters
Length of a pencil-cm/ centimeters
Length of a room- m/ meters
Length of a road- km/ kilometers
The amount of matter in an object (aka stuff)
19. What tool and unit
are used to measure
mass?
20. What is volume?
Tool- triple beam balance
21. How do you measure
Tool- graduated cylinder
Base Unit- grams
The amount of space something takes up.

the volume of a
liquid?
22. What is a meniscus?
23. How do you measure
the volume of a box,
which has a regular
shape?
24. How do you measure
the volume of a
figurine, which has
an irregular shape?
25. How do you know the
volume of a gas?
Hour___________
Base Unit- liter
The curved shape at the top of a liquid
Formula- length x width x height (l x w x h)
Units-cm3/ CUBIC units
Water displacement- steps
1. Measure the initial water level in graduated cylinder
2. Put in object
3. Measure final water level
4. Final water level – initial water level = volume of object
The volume of a gas is the volume of the container.
