Explore the science: Gold Rush
the Rough Scientists at work
The Challenges
The scientists begin by trying to collect gold from a river, building a home-made metal detector, and constructing a super accurate balance capable of weighing micro-grams of gold. The Rough Scientists have explained the science behind these challenges.
What is a carat? Discover the properties of gold and how to search for it.
Why does a metal detector make a noise when it passes over metal? Investigate the physics and gain the know-how to make one for yourself.
Is it possible to measure micro-grams? Find out how a balance works and whether it's easier to weigh light or heavy objects.
