A scientist observes that a specific plant species thrives in sunny conditions and hypothesizes that increased sunlight promotes its growth. Which statement best represents the next logical step in applying the scientific inquiry process to test this hypothesis?

  • A: Conclude the hypothesis is correct because the initial observation supports it.
  • B: Design an experiment where one group of plants receives varying amounts of sunlight and another group receives no sunlight, while controlling other factors.
  • C: Seek out existing theories that explain plant growth and assume the hypothesis aligns with them.
  • D: Immediately publish the findings, as the observation provides sufficient evidence.

Explanation

After forming a hypothesis, the next crucial step in scientific inquiry is to design and conduct an experiment or make further observations to test it. A well-designed experiment will involve manipulating the independent variable sunlight and measuring the dependent variable plant growth , while controlling other factors to ensure the results are due to the manipulated variable.
