Complex differences
A Science laboratory is a workplace for scientists where they conduct their scientific research and experiments. Majority of the brilliant ideas and inventions that we hear about, are born in these labs. While scientists use high-facility labs, almost every school has a running science lab for students too. So, find your school science lab and get ready to invent the next big thing. Make sure you are under supervision, though.
