The full moon that occurs closest to the autumn equinox is known as the Harvest Moon. Rising shortly after sunset, it treats observers to a warm, orange glow. That’s the inspiration for this week’s Art and Science Workshop project: a Harvest Moon Kaleidocope. Kids ages 4 to 10 are invited to climb aboard The Science Barge and learn how a kaleidoscope creates colorful images using reflected light from mirrors and shiny objects. Then, they can make one to take home.

When: 2 p.m., Sunday, Sept. 30

Info: The Science Barge, 99 Dock St., Yonkers; 914-513-7354; www.groundworkhv.org/programs/science-barge/events-workshops; $3 suggested donation; free admission for kids 10 and under; $5 suggested supplies fee
