The longest day

Sunrise on summer solstice at Stonehenge

On Monday, June 20th, at 06:34 pm EST, the Earth’s North Pole will be tilted as far towards the Sun as it will ever be in the year.  This marks the longest day of the year and the summer solstice in the Northern hemisphere … a time that has been revered for centuries.

In this activity, students compare length of daylight to place latitude while studying the correlation, evaluating Excel generated formulas, and appreciating the significance of this date.
