Question

which problem is best solved using the scientific method?

• design a robot that walks.
• determine how much sunlight a sunflower needs to grow.
• research the surface temperature difference between earth and mars.
• create a new recycling system for the local middle school.

Explanation:

The scientific method involves formulating a hypothesis, testing it through controlled experiments, and analyzing results. To determine how much sunlight a sunflower needs to grow, we can set up an experiment with different sunlight exposure levels (hypothesis, testing, analysis), which fits the scientific method. Designing a robot or a recycling system is more about engineering/design, and researching surface temperature differences is more about data collection/observation without the experimental manipulation core to the scientific method here.

Answer:

B. Determine how much sunlight a sunflower needs to grow.
