Bicycles and the Human Machine:
An adventurous bike ride for Members of the Exploratorium and the SF Bicycle CoalitionYou don't need to be Lance Armstrong to know how important your legs are in powering a bicycle. But what do those muscles look like? And what else is going on in your body when you haul yourself uphill and stop to catch your breath at the top? Join Exploratorium educator Ken Finn and Exploratorium writer Robin Marks as they lead an 8–10 mile excursion through the physiology of exercise. Along the way, we'll dissect chicken legs to identify muscle groups, trace the path of blood flow through a pig's heart, and take some measurements on ourselves as we challenge our bodies and take in some scenery on San Francisco’s hilly and flat streets.
Participants must be Members of either the Exploratorium or the San Francisco Bicycle Coalition and must be at least 14 years of age. This group ride requires a bicycle in good working order, a helmet, and the ability to ride ten miles in a group.

Geometron Seminar
One of the featured artists in our current Geometry Playground exhibition, John Edmark, has created The Geometron, a mesmerizing visual treat. This seminar will include a presentation and discussion where Edmark will share some of his intriguing design creations. He’ll then introduce participants to The Geometron in the Geometry Playground exhibition area.
Watch a short video interview with John Edmark on our Geometry Playground Artists-in-Residence page. In this video, Edmark explains his interest in unexpected natural phenomena and how visitors can interact with The Geometron exhibit.
Edmark has taught a wide variety of courses in the Design program of the Department of Art & Art History at Stanford University since 2003. His art and design pursuits range from organically inspired cellular and kinetic works to products for storage, kitchen, and creative play. He is named inventor on nine U.S. and foreign utility patents.

Black Sand Treasure Hunt at Ocean Beach
Join Exploratorium educator Ken Finn in search of elusive “black sand” (aka the magnetic mineral magnetite) at Ocean Beach. Tools and materials will be provided, and we’ll send you home with black sand, magnets, and an activity sheet so you can make your own miniature Black Sand exhibit—just like the one at the Exploratorium. Black Sand is one of the most popular exhibits at the museum. Visitors of all ages can’t keep their hands off it! Join us at Taraval & Great Highway, and bring the fun home.
