Scientific method includes some steps that are necessary for conducting the successful experiment.
1. Make an observation
You observe the growth of the plant under the influence of light (phototropic effect) and you notice that some plants successfully grow under artificial light. You want to compare that growth with growth under the sunlight.
2. Ask a question
How does the light influence plant growth?
Are the wavelengths of the light important?
Is natural light source (sun) better for plant growth...
3. Form a hypothesis - it is a testable potential answer to the question
For example: Sunlight induces higher phototropic reaction.
4. Make a prediction
Sunlight is richer in red and blue hues which are both extremely important to plant growth.
5. Test the prediction
Design an experiment by putting one pot with beans outside on sunlight and other under the light bulb. Other conditions such as water must be the same. Monitor their growth for about 2 weeks and measure the results.
6. Analyze the data and make a conclusion.
Answer:
Make observations. Plants appear to grow toward natural sunlight.
Ask questions. Would plants grow toward an artificial source of light?
Construct the hypothesis, and make predictions. Plants will grow toward both sources of light.
Test the hypothesis. Use two identical plants. Place one plant on a windowsill in sunlight. Place the other plant near a desk lamp. Observe the growth of the plants for two weeks.
Analyze the results, and make a conclusion. After two weeks, determine whether both plants grew toward the light source.
Test and modify the experiment. Repeat the experiment if the experiment proved the hypothesis. If not, modify the hypothesis and design a new experiment.
