Ask a question
Hypothesis
Independent Variable
The problem that this experiment is trying to
solve
What will happen if I mix liquid with
baking soda?
The expected outcome of this experiment.
Includes an “if….then” statement
If I mix baking soda with vinegar, it
will generate a gas, if I mix it with oil
or water, there will be no reaction
The part of the experiment that is changed by
the person doing the experiment
I will change the liquid that I mix with
the baking soda.
I will observe the mixture and notice if
there is a reaction. An expected
reaction would be a color change or
the creation of a gas
Dependent Variable
The part of the experiment that is affected by
the independent variable
Constant
The parts of the experiment that stay the same
in all of the trials
I will always use the same amount of
baking soda.
I will use the same volume of liquid
Control
The part of the experiment where the
independent variable is removed;
This is used as a basis of comparison
I will mix water with baking soda to
see if there is a reaction so I have
something to compare to the other
reactions.
Data
Information that is measured or observed
I will record if I see a reaction
Conclusion
The part of the experiment that answers the
problem question or leads to another question.
It tells if the hypothesis was correct and
evaluates the experiment for problems or
improvements
I will identify and communicate which
liquids react with baking soda
Ask a question
The problem that this experiment is trying to
solve
If ice floats in water, will it float in other
liquids?
Hypothesis
The expected outcome of this experiment.
Includes an “if….then” statement
If I put ice in a liquid, than it will float
Independent Variable
The part of the experiment that is changed
by the person doing the experiment
I will test if ice cubes will float in alcohol,
water and vinegar
Dependent Variable
The part of the experiment that is affected by
the independent variable
I will observe if the ice cube floats or sinks
Constant
The parts of the experiment that stay the
same in all of the trials
The liquids are the same color
The liquids are the same temperature
The same volume of each liquid
Control
The part of the experiment where the
independent variable is removed;
This is used as a basis of comparison
I put ice in water so I would have
something to compare to the other liquids.
Data
Information that is measured or observed
I will record if the ice cube floats or sinks
The part of the experiment that answers the
problem question or leads to another
question. It tells if the hypothesis was
correct and evaluates the experiment for
problems or improvements
I will identify and communicate which
liquids the ice floats in

The problem that this experiment is trying
to solve
Does the color of light affect the growth of
a plant?
Green light will make plants grow better.
Hypothesis
The expected outcome of this experiment.
Includes an “if….then” statement
Independent Variable
The part of the experiment that is changed
by the person doing the experiment
Dependent Variable
The part of the experiment that is affected
by the independent variable
Constant
The parts of the experiment that stay the
same in all of the trials
Control
The part of the experiment where the
independent variable is removed;
This is used as a basis of comparison

Conclusion
Information that is measured or observed
The part of the experiment that answers
the problem question or leads to another
question. It tells if the hypothesis was
correct and evaluates the experiment for
problems or improvements
I will grow plants under green light, red
light and sun light.
I changed the color of the lights. The red
light and the green light are different.
I will use the same kind of plant in each
trial. I will give the plants the same
amount of water. I will give the plants the
same exposure time to lights.
I will grow plants under their normal
condition, sun light, so that I have
something to compare to the other plants.
I will count the number of leaves and
flowers that are on the plant after 3 weeks
of growing.
The plants that were exposed to green
light died. The plants that were exposed
to sunlight thrived. The plants exposed to
red light survived.
