How do we get kids to take care of the planet? By helping them to enjoy it. Such is the philosophy of Envirichment, a nonprofit group that offers hands-on educational activities that encourage children to interact and care for the environment. On May 28, 10 a.m.–noon, Envirichment staff will bring pond-exploration activities to the Children’s Museum of Sonoma County in Santa Rosa. The event is free with admission ($11–$14 or free for babies 0–11 months). Find out more at cmosc.org.
