Summer solstice – the longest day
Sunrise on summer solstice at Stonehenge
On June 20th, Wednesday evening, at 7:09 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.
For members we have an editable Word doc, solutions, and our Excel sheet of data and charts.
