Social calendar filling up already? You could celebrate Earth Day and National Poetry Month at the same time at Jiyeon Song's One Day Poem Pavilion , a clever low-impact light show. Sunlight passes through holes in the sculpture (pictured above), projecting a different poem according to the season and time of day.

Writing poetry is also a great Earth Day activity for children. Find some kid-friendly songs and poems here , and then help your children submit their own Earth Day poems here .
