What is an observation?
information you notice and record using your five senses
scientific idea with a lot of evidence
something in your experiment that can change
What is an variable?
information you notice and record using your five senses
scientific idea with a lot of evidence
something in your experiment that can change
What is your favorite flavor of ice cream?
What is a scientific hypothesis?
scientific idea with a lot of evidence
educated guess/prediction for a single experiment
What is an independent variable in a scientific experiment?
the variable that changes
the variable that doesn't change
the variable that the scientist manipulates/changes
the variable that the scientist measures/the data collected
What is the independent variable in the following hypothesis?
HYPOTHESIS: If I get more sleep at night, I will be more attentive in science class.
attentiveness in science class
amount of sleep
seat location in class
what the teacher is teaching that day
In an experiment, a scientist wants to see the effect of types of music on plant growth. What factors should remain constant in the experiment?
All plants in all groups should be the same species (type of plant).
All plants in all groups should receive the same type of music.
A student creates a research question, "How does the chemical RTA affect the number of seeds that hatch?" Which of the following is a strong hypothesis?
If RTA increases, then the numbers of seeds that hatch decrease.
As RTA increases, then the numbers of seeds that hatch decrease.
If the numbers of seeds that hatch increases, then RTA decreases.
As the numbers of seeds that hatch increases, RTA decreases.
To increase validity of an experiment, a scientist can
revise the hypothesis
make-up data
repeat the experiment to collect more data
A reliable news or information source
can be trusted to provide true information
sometimes provide false information
is not useful in understanding the world
is always the first choice in a Google search
A valid experiment should have: (Select two)
only one independent variable
a control group
multiple hypotheses
small sample size
What is a constant variable?
factors you keep the same in the experiment
the group that receives the normal treatment
scientific idea with a lot of evidence
educated prediction of what the results will look like
Which of these describes the control group? (Select two)
The group that receives no independent variable or the normal version of the independent variable.
The group that receives no dependent variable or the normal version of the dependent variable.
The purpose is to provide a group to compare to the experimental groups.
The purpose is to collect more data about the independent variable to increase validity.
