Answers
1
Why is it important to do multiple trials in an investigation and average the results?
verify results, decrease the effect of outliers
develop a theory, decrease the effect of outliers
revise each step of the procedure
to test multiple variables
2
In an investigation the standard of comparison is....
the changed variable
the group that does get the independent variable
the group that does NOT get the independent variable
things that must stay the same
3
A procedure in an investigation is....
a written conclusion to an investigation
not a part of an investigation
all of the variables identified
numbered, very specific directions how to complete testing
4
What would NOT help a scientist collect accurate data in an experiment?
having a standard of comparison group to measure against
failing to record data
having controlled variables
writing a clear, testable hypothesis
5
What should be a controlled variable? "Does the amount of water affect the growth of a plant?"
plant growth
amount of sunlight
height of plant
amount of water
6
What kind of data is this? 5 cm, 15 cm, 8 cm, 9 cm, and 12 cm
quantitative
subjective
conditional
qualitative
7
True or False? Solubility rate would be graphed on the Y axis (it's the dependent variable).
True
False
8
True or False: Line graphs show changes in data over time.
False
True
9
In this experiment, the standard of comparison is the rats that are not taking the memory drug.
True
False
10
Which tool would be good for collecting quantitative data?
nose to smell
mouth to taste
ears to hear
balance to measure mass
11
What is the dependent (responding) variable: How does the amount of water affect plant growth?
amount of water
amount of plant growth
amount of sun
amount of plant food
12
What kind of data is descriptive and is collected with the senses?
summative data
qualitative data
quantitative data
numerical data
13
True or False:Investigations that are repeated over and over with the same results are invalid.
False
True
14
Pseudoscience (such as astrology)
is real! Everyone knows that!
is not supported by scientific testing or evidence.
relies on facts to make educated decisions.
15
What is NOT a characteristic of a good scientific investigation?
working with other scientists
keeping records
sloppy measuring
using expensive science equipment
16
In this experiment, the average length of time to complete the maze is graphed on the Y axis.
True
False
no way to know
17
IV: Does basketball, running, or swimming cause the largest increase in heart rate?
blood pressure
heart rate increase
the exercises (basketball, running, swimming)
resting heart rate
18
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.
reduces the effect of outliers and experimental errors
they are lazy, it's easier to graph averages!
19
An analysis of experimental data must include
quantitative data.
your hypothesis.
research.
explanation of why.
20
T or F? It's ok for an experimenter to change data to support the tested hypothesis.
True-they don't want to be embarrassed!
False- never change data! Just report your actual results!
21
True or False: To infer means to explain or tell the meaning of data after testing.
True
False
22
In the data table, the independent variable is
volume
not shown
millilters
temperature
23
A hypothesis is....
an educated guess.
a changed variable.
a conclusion.
what you measure.
24
True or false? According to the data table, the independent variable is rate of solubility.
False
True
25
During which step of the scientific method would an experimenter take measurements?
ask a question
construct a hypothesis
analyze data and make a conclusion
test your hypothesis by doing an experiment
26
Which variable goes on the y-axis on a graph?
standard of comparison
independent (manipulated)
dependent (responding)
controlled variables
27
What kind of graph shows categories of data compared to each other?
line
pictogram
pie
bar
28
What is the appropriate unit or label for measuring mass?
average mass
age
kilograms
years
29
The independent (manipulated) variable is __ by the experimenter.
measured
kept the same
found
changed
30
Which axis of the graph shows the independent (manipulated) variable?
Neither X nor Y
Both X and Y
X axis
Y axis
31
The independent (manipulated) variable is "length of time to complete a maze."
False
True
32
Scientists may reject a hypothesis (and form a new one) in this step of the scientific method.
writing a procedure
identifying variables
analyzing data/making a conclusion
determining the independent and dependent variables
33
IV?: The temperature of Diet Coke- mixed with Mentos- impacts the spray height.
soda spray height
temperature of Diet Coke
the number of Mentos
type of soda
34
Which part of the scientific method is this?
procedure
problem
hypothesis
conclusion
35
T or F? From the data, we can conclude that solubility decreases when temperature increases.
True
False
36
Scientific theories
are supported by evidence.
are guesses, so evidence doesn't matter.
are always true.
are exactly the same as hypotheses.
