Sunrise on summer solstice at Stonehenge

On Sunday, June 20th, at 11:31 pm EDT, 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 in the Northern Hemisphere and the summer solstice ... 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.
