At least the days are getting longer

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

Students make guesses; compute how long, on average, the change in daylight hours should be; and finally understand the variability in our year of daylight hours.

For Adventurer 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.
