Sun, Moon, and stars
Use observations of the sun, moon, and stars to describe predictable patterns such as the sun rising and setting, the moon changing shape, and stars appearing at night
Quick check
Can the learner describe patterns they've noticed in the sky — like the sun rising in the east, the moon changing shape over weeks, and stars coming out at night?
Ask this to see whether the topic is secure.
Topic // Mastery
What mastery looks like
- Describe the daily pattern of sunrise and sunset
- Describe the pattern of the moon's shape changing over about a month
- Explain that stars are visible at night and describe any seasonal patterns observed

The approach
For ages 6–7, learners notice, describe and PREDICT repeating sky patterns from sustained first-hand observation: the Sun appears to rise on one side, arc across the sky and set on the other each day; the Moon changes shape over about a month; and stars are seen at night (but are still present, outshone, by day). Teaching stays firmly at describing and predicting patterns, deferring their causes to later topics. Core activities are a month-long Moon-shape diary, safely marking the Sun's position at morning/midday/afternoon by reading a shadow stick (never looking at the Sun), and a day-sky vs night-sky sort. A screen 'sky over time' scrubber and static phase/Sun-arc references are useful supports, and a short sequence/sort check can assess the pattern knowledge.
Common misconceptions
- The Moon changes shape because clouds or something covers part of it, or it is a different Moon each night.
- The Moon only appears at night — in fact it is often visible during the day.
- Stars are not present in the daytime — they are there but outshone by the Sun.
- The patterns of Sun, Moon and stars are random rather than predictable.
- The Sun literally travels across the sky (recording the appearance is fine; the correct cause is deferred).
Useful representations
- A Moon-phase diary strip — the shape drawn each night across about a month.
- A daytime Sun-path arc with morning/midday/afternoon positions marked.
- A day-sky vs night-sky sort (Sun by day; stars by night; the Moon sometimes in both).
- A calendar/timeline showing the pattern repeating.
Teaching practices
- Ground the topic in first-hand and media observation over time — a month-long Moon-shape diary, marking the Sun's position morning/midday/afternoon, noticing stars only at night.
- Focus on describing and PREDICTING the pattern (what will the Moon look like next week?), matching the crosscutting concept that patterns can be observed and used to predict.
- Keep strictly to observation, not mechanism — do not yet explain why the Moon's shape changes or why the Sun appears to move; premature causes confuse at this age.
- Use consistent recording formats (shape drawings, photos, a class calendar) so the pattern emerges from the child's own data.
- Note carefully that the Sun and Moon APPEAR to move/change — record what is seen without over-claiming the cause.
- Gently correct 'stars aren't there in the daytime' — they are, but the Sun outshines them — while keeping the lesson observational.
Activities to try

Month-long Moon-shape diary
Why it works: The Moon's shape changes in a dependable, repeating cycle over about a month, so you can use past observations to predict what comes next — and the Moon is sometimes visible by day, not only at night.
- Whenever the Moon can be seen in a clear sky (often in the evening, but on some nights it is not up at a child's evening viewing time or cannot be seen at all), draw the shape of the Moon you can see, dating each drawing, and mark 'not seen' on other nights.
- Keep the drawings in order on a strip or class calendar so the sequence builds up over about a month.
- After a week or two, look back at the pattern and PREDICT: draw what you think the Moon will look like in a few nights.
- Check your prediction against the next real observation and talk about whether the shape is fattening or thinning.
- Watch for and record any time you spot the Moon in the daytime too.

Mark the Sun's daily path
Why it works: The Sun follows the same daily rising-arcing-setting pattern (only shifting slowly over the seasons), so its apparent position at a given time is predictable; the Sun is seen by day and the stars by night, while the Moon can be seen in either.
- At morning, midday and afternoon on the same day, record where the Sun appears — safely and indirectly, by marking the shadow cast by a fixed stick or object (a shadow stick); the Sun is on the opposite side of the stick from its shadow. NEVER look at or stare directly at the Sun.
- Compare the three recorded positions and describe the path: the Sun appears to climb higher towards midday (shortest shadow) and then get lower in the afternoon, fitting the pattern of rising on one side and setting on the other.
- Predict where the Sun will appear at lunchtime (or another time), then check by reading the shadow again — not by looking at the Sun.
- Sort a set of sky objects/pictures into 'seen by day', 'seen by night', and 'sometimes both' (Sun by day; stars by night; Moon sometimes in both).

Dim-light predict-observe-explain (stars hidden by day)
Why it works: A dim light is still on even when a much brighter light washes it out — just as the stars are still present in the daytime but hidden by the bright, Sun-lit sky.
- In a darkened room, turn on a small dim LED night-light.
- Before anything changes, PREDICT with a reason: when all the big room lights come on, will the little light still be shining or will it go off? Commit to your answer out loud.
- Turn on all the big lights and watch — the little light becomes much harder to see and may seem to vanish, even though it is still on.
- Dim the room again and watch it reappear.
- Say what this shows about why we can't see the stars in the daytime.
