Exploring the Moon

Overview

In this 60-minute session, students connect what they know about space to explain why the Moon matters in the solar system and how it affects Earth. This builds writing skill by organizing ideas clearly in an informative/explanatory paragraph.

Learning intentions

• Students will be able to introduce a topic and group related information together in writing.
• Students will be able to explain one way the Moon affects Earth using facts and clear organization.
• Students will be able to select and arrange information to convey an explanatory idea accurately.
• Students will be able to write over a short time frame to produce an informative response.

Success criteria

• I can describe one way the Moon affects Earth (such as tides, light at night, or stabilizing Earth’s tilt).
• I can include a clear topic sentence and supporting details in my writing.
• I can add a simple illustration that matches my explanation.
• I can revise my writing by fixing unclear words or adding one more fact.

Curriculum links

• Writing — Informative/explanatory texts that examine and convey information clearly.
• Grade 3 Writing — Write informative/explanatory texts that examine a topic and convey ideas clearly.
• Grade 3 Writing — Introduce a topic and group related information together; include illustrations when useful (CCSS.ELA-LITERACY.W.3.2a).
• Grade 3 Writing — Write routinely over shorter time frames for tasks like this informative paragraph.

Lesson structure (60 minutes)

1. 0–6 min · Warm-up conversation. Teacher prompts: “What do you already know about the Moon, and why might it matter to Earth?” Students share quick answers; teacher records 3–5 student ideas on chart paper.

2. 6–18 min · Mini-lesson: Moon significance. Teacher shows a Moon-and-Earth diagram (or hands-on model) and explains: the Moon’s gravity affects tides, the Moon’s light helps us see at night, and the Moon helps stabilize Earth’s tilt (kept simple and factual). Students repeat the key idea they choose and point to the related part of the diagram.

3. 18–30 min · Guided inquiry with models. Teacher sets up two simple stations:

• Tides station: demonstrate “pull” using a magnet/ball on a string around a bowl model of Earth with two “oceans” dots.
• Light station: use a flashlight “Sun,” a small ball “Moon,” and a dark box or sheet to show reflected light at night. Students rotate, and for each station they answer: “What is the Moon doing?” Teacher listens for accurate cause-and-effect language.

4. 30–40 min · Plan an explanatory paragraph. Teacher provides a graphic organizer with three boxes: Topic sentence / Detail 1 / Detail 2 (+ optional illustration). Students choose one effect of the Moon and draft 2–3 short facts. Teacher supports with sentence frames as needed.

5. 40–52 min · Write informative/explanatory text. Students write their paragraph:

• Start with a topic sentence: “The Moon affects Earth by ______.”
• Add one to two supporting details explaining how/why.
• Add a quick drawing (Moon + Earth + arrows or labels). Teacher conferences with one student at a time (for your single-student setting, use “coach mode”: prompt, model one sentence, then have the student try).

6. 52–57 min · Quick revision check. Teacher asks a revision question: “Does your paragraph clearly explain the way the Moon affects Earth?” Student rereads, then underlines one key fact and corrects one unclear word or adds one extra detail.

7. 57–60 min · Share + exit ticket. Student reads the paragraph aloud. Teacher asks one final question: “Name one way the Moon affects Earth from your writing.” Student answers as an oral exit check.

Resources

• Moon-Earth diagram (printed or on a tablet)
• Small balls or foam spheres (Earth and Moon models)
• Flashlight (Sun light) and dark box or dark paper backdrop
• Magnet/string or an alternative gravity demonstration materials
• Graphic organizer (Topic / Detail 1 / Detail 2 / Illustration)
• Lined paper, pencil, crayons/colored pencils
• Sentence starter cards (optional)

Assessment

• Formative: Teacher checks whether the student can state a clear Moon-to-Earth connection during the guided inquiry stations.
• Formative: During drafting and revision, teacher listens for accurate cause-and-effect wording and clear organization (topic sentence + details).
• Exit check: Student orally states one way the Moon affects Earth, matching the written response.

Differentiation

• Support for speech delay: Provide sentence starters and allow the student to dictate one detail while you scribe, then the student copies key words; use shorter chunks and repeat questions with visual pointing.
• Visual scaffolds: Require a labeled illustration (Moon, Earth, arrows) because it reduces language load and supports comprehension.
• Advanced option (since your learner is advanced): Ask for one extra precise detail (example: “Tides happen because gravity is stronger on the side facing the Moon”) and encourage “because” clauses.
• Chunking: If attention dips, offer a “plan in 3 bullets” before writing, then a “write for 5 minutes” timer.

Extension (optional)

• Research moon phases and meanings: Student chooses one phase (new, first quarter, full, last quarter), finds a simple explanation from a book or notes, and adds a 3-sentence “moon phases mini-entry” to the back of the paragraph explaining what the phase means observationally.
