A plant problem
Not what you're looking for?
You grow three plants with a light to the left of them and three plants with a light to the right of them.
The leaves of the plants with the light on the left turned toward the left and the tops of the plants grew toward the left. The leaves of the plants with the light on the right turned toward the right and the tops grew toward the right.
Does that support the hypothesis that plants respond to the light?
Help is given in these areas:
Include each step of the scientific method in the experiment.
Include an example of how you used the scientific method in everyday life.
Describe each step of the scientific method using real-life examples.

Solution Summary
A plant problem is solved using the scientific method.
Solution Preview
We can outline the scientific method like this:
Step 1: Question
Step 2: Hypothesis
Step 3: Test Hypothesis (Experiment)
Step 4: Collect Data
Step 5: Analyze Data
Step 6: Reassess Hypothesis
In this case, we have a question, "Do plants respond to light?"
Our hypothesis could be, "Yes, plants do respond to light?"
To test the hypothesis, we set up an experiment with six plants. Each plant responded to light by turning its leaves toward the light and by bending toward the light in new growth. I suppose we could have had "control" plants which just had the light from the top, but I think that the data is pretty clear. These plants exhibit what is called phototropism, or "growth affected by light." In this specific ...
