In a moon-phase study, which question best promotes predictions about future observations?

• A. What do you think the moon will look like tomorrow night?
• B. Why does the moon change color during a full moon?
• C. Where is the moon located relative to the Earth?
• D. How many phases does the moon have altogether?

Answer: (A)

Predicting future observations comes from recognizing patterns and using them to anticipate what will be seen next. In a moon-phase study, the regular cycle of lunar phases provides a pattern students can apply to forecast upcoming appearances. Asking what the moon will look like tomorrow night prompts you to use the current phase and the roughly month-long cycle to predict the next phase. This type of question invites forming a hypothesis about future data and then testing it by actual observation, a core scientific practice. Other questions focus on explaining why the moon changes color, describing where the moon is in relation to Earth, or recalling how many phases there are—these are descriptive or explanatory rather than oriented toward predicting what will be observed in the near future.
