The Singapore Science Centre is located on a six-hectare site in Jurong. At the centre, we can discover the wonders of science and technology in a fun way. Clap your hands and colorful bulbs will light up. Start a wheel spinning and it will set off a fan churning. It is a place to answer our curiosity and capture our imagination.

The centre features over four hundred exhibits covering topics like solar radiation, communication, electronics, mathematics, nuclear energy and evolution. It aims to arouse interest in science and technology among us and the general public. The centre is the first science one to be established in South East Asia. It was opened in 1977 and it now receives an average of one thousand, two hundred visitors a day. The exhibits can be found in four exhibition galleries. They are the Lobby, Physical Sciences, Life Sciences and Aviation. These exhibits are renewed annually so as to encourage visitors to make return visits to the centre.

Instead of the usual “Hands off” notices found in exhibition halls, visitors are invited to touch and feel the exhibits, push the buttons, turn the cranks or pedals. This is an interesting way to learn science even if you hate the subject. A Discovery Centre was built for children between the ages of three and twelve. This new exhibition gallery was completed in 1985. Lately this year a stone-age exhibit was built.

It shows us about the animals and people which were extinct.
