A few weeks ago, a group of 5th graders were grappling with the idea of day length. Why does day length vary in New England? First, students created a model to help them solve this problem. By creating a model, they were able to recognize that if the earth's axis was not tilted, day length would always be the same. With a tilted axis, day length changes, and seasons are created! Students discovered this all on their own with no adult/teacher direction. Pretty great thinking!
After student's developed an understanding of why day length changes, they were then asked to set to work creating a lesson about this phenomenon. The lesson needed to be appropriate for students as young as 3rd grade.
You'll see one example of such a lesson below. Just click on the image to head over to Educreate. Isn't technology wonderful?! Enjoy!
