Skills
- predict (changes in the length of day and night throughout a planet's orbital year) #dok3
- analyze (the relationship between latitudinal position and the variation of day/night length) #dok2
- explain (how changing latitude affects day and night duration) #dok2
Learning Targets
- I can identify how the length of day and night changes during a planet's orbital year. #dok1
- I can describe the relationship between latitude and the variation in day and night length. #dok2
- I can explain how the position on a planet affects the duration of daylight over a year. #dok2
- I can predict how moving to a different latitude changes the day/night cycle throughout the year. #dok3
Big Ideas
- Latitude determines how daylight varies throughout a planet's year.
- The length of day and night is not constant across a planet and changes with both latitude and orbital position.
Essential Questions
- How does a planet’s latitude affect the amount of daylight an area receives throughout the year?
- Why do some locations on a planet experience very long days or nights at certain times of the year?
- How does the tilt of a planet influence the variation in day and night lengths at different latitudes?
- How can we predict changes in day and night duration for different places on a planet during its orbit?
