Days are getting longer

Clicking on this image will take you to to the University of Nebraska's astronomy simulation in a new window.

What's your guess?  How fast are the number of daylight hours changing each day?  Will the changes be dramatic or subtle?

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.

The activity: Daylength2018.pdf

For members we have an editable Word docx, solutions, and two Excel charts and graphs to show daylight change through just January and February and daylight changes throughout the year.
