Use a science word with a cause, not only a definition. Rotation is spinning about an axis. Revolution is travel around another body. Earth’s rotation gives day and night; its revolution changes the night-side view through the year. Axial tilt together with revolution gives seasons. Moon phases come from our changing view of its sunlit half. Safety: Paper only; no Sun viewing or eclipse observation. Stop: Stop at the drawing and captions. Do not demand spelling tests or a month of sky observations.

Materials: Paper; Pencil; One paper Earth disk and one paper Moon disk 1. Write a reference bank: axis—imaginary spin line; tilt—axis lean, about 23.5° from the line perpendicular to Earth’s orbital plane; orbit—curved path around a body; gravitational force—mutual attraction between masses; atmosphere—layer of gas around a body; light-year—distance light travels in one year. 2. Add: rotation—spin; revolution—one journey around another body; lunar phases—changing appearance of the lit Moon; waxing—visible lit fraction increasing; waning—visible lit fraction decreasing; solstice—one of two yearly times of extreme solar declination, giving the longest or shortest daylight at many latitudes; equinox—Sun appears directly over Earth’s equator, with day and night approximately equal; eclipse—one body blocks light or enters another’s shadow. 3. Draw Sun, Earth and Moon as labelled circles. Put a rotation arrow on Earth, a revolution path around the Sun, an axis through Earth, a tilt mark, and a Moon orbit. Write not to scale. 4. Using the bank, compose three linked captions: rotation and day/night; tilt, revolution, solstice and equinox; lunar phases, waxing, waning and eclipse. Add a fourth sentence using atmosphere, gravitational force and light-year accurately. Done: Finish the labelled drawing and four captions, with every bank term used or pointed to meaningfully. Proof: Keep the captions and bank. Note read-aloud support, copied definitions, and any independently composed cause sentence. Stop: Stop at the drawing and captions. Do not demand spelling tests or a month of sky observations.
