A student wants to test if a bean plant will grow taller under green light than under sunlight. Select from the drop-down menu the correct step of the scientific method that each statement describes. Two identical bean plants are grown next to each other. They receive the same amount of water and sunlight. One plant is covered with a green, light-filtering plastic cover, and the other with a clear plastic cover. Measurements of the bean plants’ heights are recorded every day for two weeks.

A student wants to test if a bean plant will grow taller under green light than under sunlight. Select from the drop-down menu the correct step of the scientific method that each statement describes. Two identical bean plants are grown next to each other. They receive the same amount of water and sunlight. One plant is covered with a green, light-filtering plastic cover, and the other with a clear plastic cover. Measurements of the bean plants’ heights are recorded every day for two weeks. The student writes a lab report detailing the experimental procedure and results. The bean plant grown under the green filter will grow taller than the bean plant grown under unfiltered sunlight. Green light makes plants grow taller. The measurements show that the plant grown in natural sunlight grew taller than the green-filtered plant. So green light does not make plants grow taller. Plants are colored green, so maybe they grow more in green light.

Explanation:

1. An experiment is a procedure carried to test a hypothesis in order to support, reject or confirm the hypothesis. The steps below are for an experiment to whether bean plants grow taller under green light or sunlight.

Two identical bean plants are grown next to each other. They receive the same amount of water and sunlight. One plant is covered with a green, light-filtering plastic cover, and the other with a clear plastic cover. Measurements of the bean plants’ heights are recorded every day for two weeks.

2. Results of the experiment are recorded. The statement below indicates that results were recorded.

The student writes a lab report detailing the experimental procedure and results.

3. Predictions are expected results based on an initial hypothesis. The statement below is a prediction.

The bean plant grown under the green filter will grow taller than the bean plant grown under unfiltered sunlight.

4. A hypothesis is a statement that seeks to explain an observed phenomena. The statement below is a hypothesis:

Green light makes plants grow taller.

5. Analysis and conclusion:  the results of the experiment are analysed and conclusions are then drawn. The statement below shows analysis and conclusion based on results of the experiment:

The measurements show that the plant grown in natural sunlight grew taller than the green-filtered plant. So green light does not make plants grow taller.

6. Observations and Questions are necessary parts of the scientific method. Observing phenomena around and asking questions about our observations helps in the process of making a hypothesis. The statement below is illustrates observation and questioning:

Plants are colored green, so maybe they grow more in green light.
