All ages are invited to join us at the Lapham-Patterson House for a special weekday edition of Make History! A Salute to Spring! March 20 is the vernal equinox, a day marking the start of spring and a day in which there are equal day and night hours. On this day each year, a unique phenomenon occurs on the third floor of the Lapham-Patterson House. Science, history, and creativity collide for a unique celebration of spring’s arrival. To view nature’s trick of light and shadow, please visit the Lapham-Patterson House between 2:30pm and 5:30pm. The peak viewing hour for the “Equinox Effect” is 3:30-4:30pm. In addition to viewing the light show, the event will include crafts and activities based on the science of the equinox. This event is presented at no charge and all are welcome.
