Question
Maria hypothesizes that the amount of light in an environment affects the growth of algae living in that environment.Which of the following is the best type of investigation for Maria to perform in order to test her hypothesis? A. observe algae in nature B. build a computer model of algae growth C. conduct a controlled experiment D. collect and observe different specimens of algae
Solution
C. Conduct a controlled experiment
This is the best option because it allows Maria to control the amount of light the algae is exposed to and observe the effects on its growth. She can have different groups of algae exposed to different amounts of light and compare their growth rates. This way, she can directly test her hypothesis. Observing algae in nature or collecting different specimens doesn't necessarily allow her to control the amount of light they receive. Building a computer model could be useful, but it's not as direct or reliable as conducting a real-life experiment.
