The Maryland Science Center is more than fun. You can enjoy the three floors of exciting things, watch the larger-than-life play on the 4th floor, and travel to other worlds, to far away stars, on the 5th floor.
Don’t just look. You are expected to feel, to turn, to push. Build your own house and learn why it stands or falls. Use computers to work out plans just as famous scientists have done. There is always something new to learn at the Maryland Science Center.
Children and group visitors enjoy half price.
The excitement of the Maryland Science Center does not end when you leave. Visit the Science Store for a gift you’d like to keep. Electron/e jewelry (电子珠宝), s, books, and more—take part of the Science Center home with you.
