A SCIENCE MUSEUM should be a place of discovery. But many offer their young visitors a chance to discover little more than their own shortcomings. Difficult scientific principles, arcane technical terminology and abstruse graphic representations send children a message of criticism and blame. "This is what you don’t know." "This is what you can’t understand." "How did you get so dumb?" Here at the Self-Explanatorium we have a different message. We say to children, "Come discover the joy of learning to know how to grasp what you can appreciate by exploring the understanding of knowledge you already are aware that you have the wisdom to possess." And to frazzled parents we say, "Sit and relax while we entertain the kids. Haven’t you done enough already?" Turn the page to begin your exploration!
