1
A factor that changes because of the independent variable:
hypothesis
controlled variable
dependent variable
independent variable
2
"I propose that student achievement will be based on the amount of studying done" is a:
Scientific Theory
Conclusion
Hypothesis
Scientific Law
3
Which of these would not include dependent and independent variables?
effect of different mass on falling object
effect of temp on bacteria reproduction
model car air flow resistance at different wind speeds
observing bird populations
4
Which of the following is an example of an observation?
How much water a plant needs per day
An object in motion will continue until acted on by an outside force.
The height of my plant is 12.2 cm
Based on evidence I gathered, the best way to feed a cat is in a bowl.
5
Will the amount of plant food affect the height of a plant? What is the independent variable?
amount of light
The amount of plant food
height of the plants
The soil
6
What is a characteristic of a GOOD experiment?
results can be replicated
variable procedures for collecting data
small sample size for collecting data
uncontrolled surroundings
7
Hypothesis: The more sunlight a plant receives increases the number of seeds. The light is the
controlled variable
observed variable
dependent variable
independent variable
8
Which of the following describes a scientific law?
Based on opinion.
explain why events and conditions occur as they do
Can be created without experimentation.
Describes what always happens.
9
Scientific law and a scientific theory are similar in that both:
represent a large amount of scientific investigation and evidence.
explain why events and conditions occur as they do in the natural world.
are based on what we expect to happen based on natural history.
describe the events that can be observed in nature.
10
Al wants to use 3 baits for his fishing to see which catches more fish. The bait is the:
independent variable
hypothesis
controlled variable
dependent varaible
11
Ashley wonders on the effects of water for seed sprouting. How can Ashley determine if her results are replicable?
Ashley can ask other students to perform the experiment.
Ashley can carefully record her observations.
Ashley can conduct her experiment with large sample sizes.
Ashley can perform the experiment multiple times.
12
During a scientific investigation, which step will a scientist do first?
conclusion
organize data
experiment
state the problem
13
How is a scientific theory different from a regular theory?
Scientific theory is about science
scientific theory is based on popular opinion
A scientific theory is about physics and math
Scientific theory concerns nature and is supported by data
14
After doing an experiment, how should you check to see if conclusions are valid?
Make a graph to view your data.
Repeat the experiment to see if the first set of data were accurate.
Conduct the experiment with more independent variables
Publish a report with your findings.
15
How can a scientific theory change over time?
older models based on opinons
different scientists have different ideas
New evidence leads to changing the current scientific theory
The scientists are completely wrong about a theory
16
How does technology increase the advancement of science?
identifying the variables
generating explanations of phenomena
planning the experiment
gathering the data for the investigation
17
Why is it important to keep accurate and precise records of everything done in an experiment?
Make the data easier to understand for regular people
Allow you to repeat the experiment and check results
ensure that the hypothesis is correct
Make sure data is conclusive
18
During a scientific investigation, which step occurs after a scientist collects data
Follow the procedure
Plan the experiment
Draw conclusions
Form the hypothesis
19
How are biology (study of life) and astronomy (study of space) similar?
They both sound sciencey
Both use telescopes
Both subjects are based on the same scientific principles.
Both reach the same conclusions
20
“What kind of sound makes the best music?” Which of the following is correct about the statement:
The question is not scientific because it involves personal opinions
is scientific because it can be answered by gathering data
It is scientific because the study of sound is scientific topic
The question is not scientific because it is too difficult to observe
21
What makes cell theory a theory and not a law?
it is a guess
It explains how cells relate to life
It says what happens
It is just a hypothesis
22
How is universal confirmation achieved about a scientific topic?
through many repetitions of an experiment by the original scientist observi
through many replications of an experiment and debate by other scientists
through five scientists observing a result that was predicted and repeating
through the decisions made by only the top experts in the field of science
23
What makes Newton's second law of motion a law and not a theory?
the outcome it predicts may vary
It has been tested but not proven
it shows a mathematical relationship (equation)
it cannot be tested
24
Hypothesis: The more sunlight a plant receives increases the number of seeds. The seeds are the
independent variable
controlled variable
manipulated variable
dependent variable
25
Which statement
best
describes the term theory as used in the gene-chromosome theory?
A theory is a law that is never revised
A theory refers to an assumption
A theory refers to a scientific explanation that is strongly supported
A theory is a hypothesis that has been supported by one experiment
