Sci. Method, Graphing, and Topography
Question 1
What is the first step in the scientific method?
Forming a hypothesis
Analyzing data
Asking a question
Drawing a conclusion
Question 2
A hypothesis must be
complex
testable
always correct
proven true
Question 3
What do scientists do after making observations?
publish results
create a graph
form a hypothesis
start over
Question 4
What is the purpose of an experiment?
argue with other scientists
to prove opinions
to test a hypothesis
to write a book
Question 5
What is the variable changed by the scientist?
dependent
independent
controlled group
experimental group
Question 6
The factor that is measured in an experiment is called
independent variable
hypothesis
dependent variable
constant
Question 7
What should you do if your hypothesis is not supported by the data?
change the data
start over again with a new question
ignore the results
revise your hypothesis
Question 8
Which of these best describes a control group?
The group with the variable being tested
group that receives no experimental treatment
the group with the most changes
the group that changes the hypothesis
Question 9
Why are repeated trials important in an experiment?
to waste time
to ensure results are reliable
to prove the scientist is right
to use more materials
Question 10
Which is not a step of the scientific method?
ask a question
form a hypothesis
conduct an interview
analyze data
Question 11
Data collected in an experiment is used to
create a hypothesis
make observations
draw a conclusion
write a question
Question 12
Which of the following is a testable hypothesis?
cats are the best pets
music sounds nice
plants grow faster with sunlight
math is hard
Question 13
A scientific theory is
a guess
a proven law
a well-tested explanation
a personal belief
Question 14
Why must experiments be repeatable?
to keep students busy
to confirm the results are consistent
to make the experiment longer
to add more variables
Question 15
In which step of the scientific method do you record what happened?
forming a hypothesis
analyzing data
observing and collecting data
communicating results
Question 16
What does it mean to analyze data?
guess what the results mean
change the results
look for patterns or trends in the results
throw away bad results
Question 17
Peer review is important because it
slows down the process
adds more opinions
allows copying of results
ensures the experiment was valid and reliable
Question 18
What kind of graph is commonly used to display experimental data?
line graph
circle graph
flowchart
venn diagram
Question 19
What is the last step in the scientific method?
forming a hypothesis
drawing a conclusion
collecting data
asking a new question
Question 20
What is a constant in an experiment?
a variable that changes
A factor that stays the same
a type of graph
the outcome
Question 21
Why is it important to control variables in an experiment?
To make it easier to write
to shorten the experiment
to confuse the reader
to ensure only one factor is tested
Question 22
What can scientists do to communicate their results
keep them secret
tell only their friends
publish in journals or present findings
destroy their notes
Question 23
Which of these statements about a hypothesis is TRUE?
it must be correct
it must be untestable
it's an educated guess
it's a fact
Question 24
Which of these shows the correct order of steps in the scientific method?
Hypothesis → Conclusion → Question → Data
Question → Hypothesis → Experiment → Analyze Data → Conclusion
Experiment → Hypothesis → Question → Conclusion
Conclusion → Experiment → Hypothesis
Question 25
What is the difference between a theory and a law?
A theory is proven, a law is not
a law describes what happens, a theory explains why
they are the same
a theory becomes a law over time
Question 26
On a topographic map, contour lines that are close together indicate:
flat area
steep slope
a valley
a riverbed
Question 27
The elevation difference between adjacent contour lines is called the:
map scale
contour interval
relief
index line
Question 28
Which direction does a river flow on a topographic map?
toward higher elevation
in the direction the contour lines bend
opposite to the direction the contour lines "point"
parallel to the contour lines
Question 29
The term "relief" refers to
the average elevation of the map
the difference between the highest and lowest elevation
the steepness of a slope
the distance between contour lines
Question 30
On a line graph, the independent variable is usually plotted on the
Y axis
X axis
legend
grid lines
Question 31
The purpose of a graph in science is to
replace all numerical data
make data visually easier to interpret (read and understand)
eliminate the need for experiments
predict data with no evidence
Question 32
Which graph type is best for showing different parts of a whole (a breakdown of each "group")?
line graph
bar graph
pie chart
scatter plot
Question 33
The best reason for using a line graph instead of a bar graph is
you want to compare categories
you are showing change over time
you have no numerical data
you are showing percentages
Question 34
A graph's title should
be one or two words
describe what the graph shows clearly
list every data point
match the y-axis label exactly
Question 35
If the x-axis shows “days” and the y-axis shows “height of plant,” then the dependent variable is:
days
height of the plant
the plant itself
the graph title
Question 36
The y-axis is usually
vertical, showing the dependent variable
horizontal, showing the independent variable
always labeled with time
plotted without units
