Ah, the days are getting longer

Daylight Hours Explorer

Clicking on this image will take you to to the University of Nebraska’s astronomy simulation.

What’s your guess as to how fast the number of daylight hours will change each day from now until June 21st?  Will the changes be dramatic? Will the lengthening days be only a subtle change?

Students make guesses; compute how long, on average, the change in daylight hours should be; play with a cool piece of comparison technology; and finally understand the variability in our year of daylight hours.
