Longer and Shorter Days
Read daylight data for Atlanta through the year and describe the pattern: longest in June, shortest in December.
Warm-up, learn, try it together, practice, then a quick check. About 15 minutes.
What children learn in Level 2
- Have you noticed that it's still light at dinnertime in summer, but dark in winter? Day length changes through the year.
- Here's real data for Atlanta: about how many hours of daylight it gets in each month.
- The days grow longer from January to June, the longest, then shorter until December, the shortest. Then the pattern repeats every year.
- A whole day is 24 hours, so when daylight is long, night is short. In June, Atlanta gets about 14 and a half hours of daylight and only about 9 and a half of darkness.
Georgia Standards of Excellence in Science:
- S4E2.a — Develop a model to support an explanation of why the length of day and night change throughout the year.
