The Changing Moon

Active learning helps students grasp the dynamic nature of the lunar cycle by engaging them directly with observation and modeling. Hands-on activities transform abstract concepts into tangible experiences, fostering deeper understanding and retention of how we perceive the moon's changing appearance.

Activity 01

Outdoor Investigation Session300 min · Individual

Moon Phase Journal: Daily Observations

Students will observe the moon each night (or as visible) and record its shape and position in a dedicated journal. They can draw what they see and note the time of observation.

Explain why the moon appears to change shape every few nights.

Facilitation TipDuring the Moon Phase Journal activity, encourage students to note not just the shape but also the moon's location in the sky relative to landmarks, reinforcing the concept of observation from Earth.

Activity 02

Lunar Cycle Model Building

Using a light source (representing the sun), a ball (the moon), and a student's head (the Earth), students can physically model how the changing angles create the different moon phases.

Justify why the moon does not actually disappear during a New Moon phase.

Facilitation TipWhen facilitating the Lunar Cycle Model Building, remind students to consistently move the 'moon' ball in the same direction (counter-clockwise) around the 'Earth' person to accurately represent its orbit.

Phase Identification Relay

Prepare cards with images of different moon phases. Students race to correctly order the phases or match phase names to images.

Predict the impact if the moon's brightness were comparable to the sun's.

Facilitation TipIn the Phase Identification Relay, circulate to ensure students are discussing and justifying their placement of phase cards, reinforcing the sequence and visual characteristics of each phase.

A few notes on teaching this unit

This topic benefits from a concrete, observational approach. Teachers can effectively guide students by emphasizing that the 'changing' moon is about perspective, not physical transformation. Avoid simply lecturing about phases; instead, use student-led observation and modeling to address misconceptions directly.

Students will be able to accurately track and describe the moon's phases over time, demonstrating an understanding that the moon itself does not change shape. Successful learning is evident when students can articulate the relationship between the Earth, Moon, and Sun's positions and the resulting observed phases.


Watch Out for These Misconceptions

  • During Lunar Cycle Model Building, watch for students who incorrectly position the 'moon' ball or 'Earth' person, suggesting a misunderstanding that the moon changes shape itself.

    Redirect students by having them physically demonstrate how the light from the 'sun' source illuminates different parts of the 'moon' ball as it orbits the 'Earth' person, highlighting that our view of the lit portion changes.

  • In the Moon Phase Journal, students might draw a completely black circle for the new moon, implying it has vanished.

    When students record a new moon, prompt them to use the Lunar Cycle Model. Ask them to show where the moon is in relation to the Earth and Sun during this phase and discuss why we can't see the sunlit side from Earth.
