Drag the tiles to the correct boxes to complete the pairs. Your teacher asks you to design an experiment that shows how plants respond to changes in their environment. You have two identical plants to do your experiment, and you may add any other equipment of your choosing. Using the scientific method, design an experiment that meets your teacher’s criteria. Match each step of the scientific method with a step of the experiment.
Make observations.
Ask a question.
Test the hypothesis.
Analyze the results, and make
a conclusion.
Test or modify.
Put one plant under a white lightbulb, and
place the other plant under a red lightbulb.
Measure the growth of the two plants.

If you observe no change, repeat the
experiment with different colors of
lightbulbs. If there is a change, repeat
the experiment for one or two more trials
to ensure that the color of the lightbulb
contributes to the change.
arrowRight
Do plants grow as well under a different
color of light?
arrowRight
Determine whether the plant grown under
the white lightbulb or the plant grown
under the red lightbulb grew better.
