Over a two-month period, a kindergarten teacher has taken pictures of the phases of the moon. During that time, the teacher and students have pasted each new picture on the corresponding date on a large calendar. The class has had several lively discussions about the students' own observations of the moon and its changing appearance. In the context of developing students' science skills, which of the following questions would be most appropriate for the teacher to pose at this time?

• A. What do you think the moon will look like tomorrow night?
• B. How far away is the moon on different nights?
• C. What caused the moon to appear brighter tonight?
• D. Why does the moon sometimes disappear from view?

Answer: (A)

The main idea here is helping young learners practice predicting from what they have observed. By collecting and posting pictures of the moon’s phases on a calendar, the class has a simple, visible pattern showing how the moon changes over time. Asking what the moon will look like tomorrow night invites students to use that pattern and the data they’ve gathered to make a forecast, which is a foundational science skill at the kindergarten level. It also encourages reasoning with evidence from their own observations and discussions.

The other questions require ideas that are either too abstract or not directly tied to the data the class has been collecting. Thinking about how far away the moon is involves a concept beyond what kindergarteners typically encounter. Asking why the moon looks brighter tonight or why it disappears touches on causes and explanations that can be explored later, but predicting the next appearance directly builds on the observed sequence and strengthens inquiry habits right now.
