S2.9.3 For the adult
The Sun seems to move
Why does the Sun seem to cross the sky?
What this chapter teaches
The Sun seems to cross the sky from east to west because the Earth turns toward the east. A shadow stick can find east and west, so no compass is needed.
Three questions to ask
There is no one right wording. Listen for the idea.
- Why does the Sun seem to move across the sky?
- How could you use a stick and two stones to find east and west?
- Which way will a shadow point in the afternoon, and why?
After the chapter, the learner can
- Explain why the Sun seems to cross the sky east to west
- Find east and west with a stick and two shadow marks
What they copy into their notebook
The Earth turns toward the east. So the Sun seems to rise in the east. It seems to set in the west. A shadow stick finds them. Stone 1 is west. Stone 2 is east.
