Humans have marked the vernal equinox - when equal hours of daylight and darkness signal winter's end - since ancient times. The Sphinx, Stonehenge, and Mayan pyramids all align with its sunrise. Today's rites of spring run from a "festival of colors" in India to NCAA basketball's March Madness. Your engineers will step back in time with this month's activity. See who can beat the clock - or buzzer!

Activity: Build a Sundial
Students in grades 6 to 8 investigate the accuracy of sundials and the discrepancy that lies between "real time" and "clock time" by tracking the position of the sun as they make a shadow plot, a horizontal sundial, and a diptych sundial.
