Inside, children explore a watershed wall showing the plants and animals of a creekside ecosystem, open discovery drawers, try interactive lake and creek habitat activities, and read from a shelf of science and nature books. A 'play in the park' corner lets little ones build a picnic from food-shaped toys, and YSI's live animal ambassadors are on view. Behind the center, the short Viola Anderson Native Plant Trail is good for a quiet walk. YSI also offers drop-in-style community programs on weekends, such as arthropod meet-and-greets and teen chinchilla sessions (registration required). ## Similar picks in San Jose - [Science Fridays & Science Saturdays at the EcoCenter](https://grassyknees.com/san-jose/activities/science-fridays-and-science-saturdays-at-the-ecocenter--listing-28726cf98e800dad2a6afbe6) — Sat, Oct 24 (+8 more dates) · 10:00 AM – 1:00 PM · Environmental Volunteers EcoCenter, Palo Alto · All ages · Free · checked Oct 24.
