S3.12.6 For the adult
Day length and the Sun's height
Why are some days longer than others? Can I track the Sun with a stick?
What this chapter teaches
Day length changes through the year, more and more away from the equator, and the north and south have opposite patterns. A high midday Sun gives a short shadow, and the shadow points away from the Sun. The learner graphs day length and tracks a stick's shadow.
Three questions to ask
There is no one right wording. Listen for the idea.
- Why are the days longest in different months in the north and the south?
- What does a shorter midday shadow tell you about the Sun?
- Which way does a midday shadow point where you live, and why?
After the chapter, the learner can
- Graph day length through a year from a table
- Track the Sun's midday height by measuring a stick's shadow
What they copy into their notebook
Day length changes through the year, except near the equator. North and south have opposite patterns. A high midday Sun gives a short shadow, pointing away from the Sun.
