When leaving a movie theater, a person notices that the sidewalk is now wet. If the person assumes it rained during
the movie, the person is making...
a hypothesis.
an inference.
an observation.
a prediction.
Alexander was studying the effect of playing rock music on plant growth. One of the plants was exposed to rock music for 24 hours a day for a period of 6 weeks. Data on the growth of the plant was collected at the end of each week and plotted in a graph. Based on the data, which would be the MOST reasonable measurement at the end of an 8 week period?
2 dm
6 dm
8 dm
16 dm
When designing an experiment, scientists will test a relationship between a “cause” and an “effect.” The “effect,” also represented by what the scientist measures and records, is known as the
dependent variable
constant
independent variable
control group
The work of scientists generally begins with
analyzing results
drawing conclusions
asking questions
testing a hypothesis
The control group in an experiment is the
point at which observations are made.
one that does not receive any experimental treatment.
careful measuring and recording of data.
point at which variables are made.
Thinking that it is going to rain when you see dark clouds in the sky is a (an)
variable
theory
inference
observation
Science should be based on
feelings
observations
opinions
faith
Which of the following is an example of an observation?
My favorite food is French fries.
The frog has brown stripes on its back.
The insect was lonely so it flew away.
Biology is the best class ever.
An inference is
the same as an observation
a way to avoid bias
a statement involving numbers
a logical interpretation of an observation
A scientific Law is
a proposed explanation for an observation
is basically a hypothesis
is a statement based on repeated experimental observations that describes a phenomenon in nature
an observation about the world around us
The _____________ variable is variable that the experimenter has control over. The reason the experiment is being done. It is what I change.
controlled
independent
dependent
first
The study of life is:
zoology
botany
microbiology
biology
The _________________variable is the factor that is measured in an experiment.
dependent
independent
controlled variables
constants
Scientific Inquiry starts with:
a hypothesis
an observation or question
an experiment
a conclusion
Constants in an experiment are:
variables that are changed by the experimenter
variables that stay the same in the control and experimental group
variables that are effected by the manipulated variable
the standard for comparison in an experiment
A controlled experiment is an experiment in which:
only one variable is being tested
only one constant is added then taken away
only two variables are tested
only two variables are measured
All of the following is qualitative data EXCEPT:
The baking soda and vinegar bubble up and overflowed out of the beaker
the beaker got really cold after mixing the two substances
the baking soda and vinegar make a stinky smell
the mass of the baking soda and vinegar was 53.2 g
An experiment:
is a problem to be solved.
may be revised or replaced.
is always true.
is testing the hypothesis.
If you wanted to display data that shows trends over time you would use a/an:
bar graph
pie chart
line graph
If you wanted to display data that was counted or data that is non numerical you would use a/an:
bar graph
line graph
a pie chart
A scientific theory is considered a/an:
proposed explanation of a natural phenomenon
experiment
set of observations about the world around us
well substantiated explanation acquired through the scientific method and repeatedly tested and confirmed through observation and experimentation
All of the following is quantative data EXCEPT:
The mass of the baking soda is 22.0 g and the mass of the vinegar is 31.2 g.
the beaker got really cold after mixing the two substances
the volume of the vinegar is 50.0 mL
the mass of the baking soda and vinegar was 53.2 g
