Answers
1
What kind of data is this? 5 cm, 15 cm, 8 cm, 9 cm, and 12 cm
conditional
quantitative
qualitative
subjective
2
Which part of the scientific method is this?
conclusion
problem
hypothesis
procedure
3
In an investigation the standard of comparison is....
the group that does not get the independent variable
the measured variable
things that must stay the same
the changed variable
4
In this experiment, the standard of comparison is the rats that are not taking the memory drug.
True
False
5
IV: Does basketball, running, or swimming cause the largest increase in heart rate?
heart rate increase
resting heart rate
blood pressure
the exercises (basketball, running, swimming)
6
What would NOT help a scientist collect accurate data in an experiment?
failing to record data
having a standard of comparison group to measure against
writing a clear, testable hypothesis
having controlled variables
7
The independent (manipulated) variable is "length of time to complete a maze."
True
False
8
T or F? From the data, we can conclude that solubility decreases when temperature increases.
False
True
9
Why do scientists take averages of the data from multiple trials?
There would be too much data, otherwise.
They all really, really like math. A lot.
they are lazy, it's easier to graph averages!
reduces the effect of outliers and experimental errors
10
A hypothesis is....
a conclusion.
a changed variable.
what you measure.
an educated guess.
11
In this experiment, the average length of time to complete the maze is graphed on the Y axis.
no way to know
False
True
12
An analysis of experimental data must include
research.
your hypothesis.
explanation of why.
quantitative data.
13
What kind of data is descriptive and is collected with the senses?
summative data
quantitative data
qualitative data
numerical data
14
Scientific theories
are exactly the same as hypotheses.
are supported by evidence.
are always true.
are guesses, so evidence doesn't matter.
15
What is the appropriate unit or label for measuring mass?
average mass
kilograms
years
age
16
Pseudoscience (such as astrology)
is real! Everyone knows that!
is not supported by scientific testing or evidence.
relies on facts to make educated decisions.
17
The independent (manipulated) variable is __ by the experimenter.
measured
found
changed
kept the same
18
What kind of graph shows categories of data compared to each other?
bar
line
pictogram
pie
19
Why is it important to do multiple trials in an investigation and average the results?
develop a theory, decrease the effect of outliers
verify results, decrease the effect of outliers
revise each step of the procedure
to test multiple variables
20
IV?: How does the temperature of the Diet Coke (when mixed w/Mentos) affect the spray height?
soda spray height
the number of mentos
temperature of Diet Coke
type of soda
21
What should be a controlled variable? "Does the amount of water affect the growth of a plant?"
amount of sunlight
amount of water
height of plant
plant growth
22
A procedure in an investigation is....
not a part of an investigation
a written conclusion to an investigation
all of the variables identified
numbered, very specific directions how to complete testing
23
Which tool would be good for collecting quantitative data?
ears to hear
nose to smell
mouth to taste
balance to measure mass
24
What is NOT a characteristic of a good scientific investigation?
working with other scientists
using science equipment
keeping records
sloppy measuring
25
Which variable goes on the y-axis on a graph?
standard of comparison
dependent (responding)
independent (manipulated)
controlled variables
26
True or False: Line graphs show changes in data over time.
False
True
27
True or False? Solubility rate would be graphed on the Y axis (it's the dependent variable).
False
True
28
Scientists may reject a hypothesis (and form a new one) in this step of the scientific method.
identifying variables
writing a procedure
analyzing data/making a conclusion
determining the independent and dependent variables
29
T or F? It's ok for an experimenter to change data to support the tested hypothesis.
False- never change data! Just report your actual results!
True-they don't want to be embarrassed!
30
True or false? According to the data table, the independent variable is rate of solubility.
True
False
31
True or False:Investigations that are repeated over and over with the same results are invalid.
True
False
32
Which axis of the graph shows the independent (manipulated) variable?
X axis
Both X and Y
Neither X nor Y
Y axis
33
What is the dependent (responding) variable: How does the amount of water affect plant growth?
amount of plant growth
amount of sun
amount of water
amount of plant food
34
During which step of the scientific method would an experimenter take measurements?
ask a question
test your hypothesis by doing an experiment
construct a hypothesis
analyze data and make a conclusion
35
In the data table, the independent variable is
temperature
millilters
volume
not shown
