Earth & Space Vocabulary
Use technical vocabulary for Earth's motion and the wider universe — rotation, revolution, axis, tilt, orbit, light year, gravitational force, atmosphere, lunar phases, waxing, waning, solstice, equinox, eclipse — and apply these when explaining day and night, the seasons, and the Moon's phases
Lesson
Set out your lesson
“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.”
Bring to the table
- Paper
- Pencil
- One paper Earth disk and one paper Moon disk
Extra for the adult
Worked example. I write: Waxing means the visible lit part grows as the Moon orbits Earth; it is not Earth’s shadow growing. A lunar eclipse is different because Earth’s shadow falls on the Moon during a special alignment.
Optional challenge. Explain why an equinox does not mean exactly twelve hours of daylight everywhere.
What to notice. Keep the captions and bank. Note read-aloud support, copied definitions, and any independently composed cause sentence.

Check understanding
- Use 'rotation' and 'revolution' correctly to describe Earth's two distinct types of movement and explain what each causes
- Use 'waxing' and 'waning' to describe the Moon's phases and explain what causes them
- Apply 'solstice' and 'equinox' correctly when explaining why seasons exist and why day length varies
“Can your child explain the difference between the Earth rotating and the Earth orbiting the Sun — using the actual science words 'rotation' and 'revolution'?”
