Science centers connect people with science. Science centers give science a presence in the community and offer people of all ages and backgrounds the opportunity to ask questions, discuss, and explore. Visit a science center, and you’ll encounter hands-on exhibits like giant levers, wave tanks, and walk-in kaleidoscopes. While you are there, you may go to a demonstration, watch a skyshow or big-screen film, participate in a workshop, or even take part in a debate about a current issue like bioethics. In the process, you’ll experience the pleasure of lifelong learning, whether with family, friends, or on your own. At science centers, everyone is welcome.
