Lunar Cycle Wonder

Overview

Today students begin a 6-lesson unit, “Making Sense of Planet Earth and Beyond,” by learning how we see different moon phases and why the moon looks different across a month. Students will practise careful observation, record what they see, and create a simple class tracking chart.

Learning intentions

• Students will notice that the moon appears to change shape in the sky over time.
• Students will describe and match the ideas of new moon and full moon to what we can see.
• Students will use a simple chart to record observations over several days.
• Students will explain their thinking using science words such as moon, phase, shadow, and sky.

Success criteria

• I can name and describe new moon and full moon.
• I can say that moon shapes change because of how we see the moon from Earth.
• I can record observations on a class chart using pictures or simple words.
• I can ask a question or share a reason for my ideas (not just a guess).

Curriculum links

• Science: Living World, Physical World—developing understanding of Earth and space through observation and modelling.
• Scientific inquiry: making careful observations, recording results, and using evidence to answer questions.
• Key Nature of Science: asking questions, using data (observations), and communicating ideas.

Lesson structure (60 minutes)

1. 5 min — Welcome and hook (talk + show)

• Show today’s moon picture cards (new moon, first quarter, full moon, last quarter) without labelling yet. Ask: “Which picture looks most like the moon you see most often?”
• Set the unit context: “Over the next 6 lessons, we’ll learn how Earth, the moon, and the sun relate.”

2. 10 min — Mini-lesson: what is a lunar phase?

• Use a simple model with a torch (sun) and a ball (moon). Keep Earth as “where we are standing” around the room.
• Explain: “The moon does not change itself like a flip book. It looks different because sunlight hits it and we see different parts as it travels around Earth.”
• Introduce and practise vocabulary: moon, phase, shadow, sky.

3. 10 min — Whole-class sort: new moon & full moon

• Give pairs a set of unlabelled phase images. Students sort into two groups: “new moon” (very dark/not easy to see) and “full moon” (bright, round).
• Teacher checks misconceptions: some students may think the moon “turns on” or “vanishes.” Reinforce the idea of “what we can see” from Earth.

4. 12 min — Guided observation practice (station activity)

• Students rotate through two stations:
• Station A: “Moon look and match” using a short sequence of printed moon images (teacher-selected, age-appropriate).
• Station B: Draw a moon you see today (or imagine seeing) and write one sentence: “Today I notice… because…”
• Teacher circulates, prompting with sentence stems: “I think it’s a new moon because…” “I notice the moon looks…”

5. 10 min — Create the class lunar tracking chart

• In groups of 3–4, students add a small “day box” to a large class chart. Each day box includes:
• Date space
• Picture space (circle/phase drawing)
• One word space (e.g., dark, bright, thin, round)
• Agree on how to record safely: observe from a classroom-safe window or with caregiver guidance, and never stare at the sun.

6. 8 min — Share and reflect

• Groups share one idea using the “claim, evidence, question” frame:
• Claim: “I think…”
• Evidence: “I noticed…”
• Question: “I wonder…”
• Teacher summarises key learning: “New moon is when the moon is hard to see. Full moon is when we see a bright round moon. Over time, the moon’s appearance changes.”

7. 5 min — Exit ticket and next step

• Each student completes an exit ticket: draw either a new moon or a full moon and write: “It looks like… because…”
• Explain homework/next lesson task (low pressure): “Tomorrow (or next viewing), try to draw the moon you can see and bring it in—or tell a family member what it looked like.”

Resources

• Printed phase picture cards (at least new moon and full moon, plus extra quarter phases)
• Torch and small ball (to demonstrate sun–moon–Earth viewing)
• Large class chart paper and markers
• Student activity sheets for station work (matching and drawing)
• Exit ticket slips (half-page)
• Timer and photo cards for engagement
• Visual word bank (moon, phase, shadow, sky, new moon, full moon)
• Seating plan with calm space option for a student with ADHD/anxiety

Assessment

• Formative: teacher observes pair sorting accuracy and vocabulary use during stations.
• Formative: collect exit tickets to check understanding of new moon/full moon and ability to give a reason.
• Ongoing: review student contributions to the class lunar tracking chart (picture clarity and effort to record accurately).

Differentiation

• Support: provide sentence starters and a word bank during drawing/writing; allow verbal recording for the student who finds writing difficult.
• Support (ADHD): clear station timers, visual checklist of steps, and a brief movement break between stations.
• Support (anxiety): offer “choose one” options (draw only, or draw plus one word) and allow quiet sharing with teacher.
• Extension: students label drawings with “thin/half/round” and add an extra question (e.g., “Why does it look different at night?”).
