At Least the Days Are Getting Longer

Link: At Least ...

Here's another helpful lesson from Yummy Math! This lesson explores the gradual increase in daytime hours from winter to summer and decrease from summer to winter. There's a bit of measurement and data involved as students calculate daylight hours and interpret tables. Students are also asked to consider whether the data will follow a linear progression and to do some basic calculations.

This lesson involves a flash animation tool. Please ensure your students can view flash before assigning the task. Students will need Internet access to complete this lesson because of both this and other embedded links.

Additional tip for teachers: This lesson has been written by someone in the Northern Hemisphere. While he does give a link for students to look up their own location's sunrise and sunset, teachers in the Southern Hemisphere would be well-served to adjust the lesson slightly. Teachers at the Equator should note that their students may not find this lesson very interesting since sunrise and sunset are fairly consistent year round.
