This 'Rough Science' includes 6 programmes from Series 3 of the popular TV programme.
Gold Rush Five scientists undertake an epic journey on the other side of the world to hunt for gold. Kate Humble joins the team of modern day prospectors as they follow in the footsteps of the original gold pioneers on the rugged west coast of New Zealand's South Island.
Shakers The scientists turned gold prospectors continue their epic search for gold in the wilds of New Zealand's South Island. Presenter Kate Humble struggles with the team as they battle to extract enough gold to make a souvenir by the end of the series. To add to the half a gram they extracted in the first week, they adopt increasingly bizarre methods to get rich and solve science puzzles.
Quakers The scientists continue to look for gold in New Zealand, following in the footsteps of the original prospectors from 1860. Ellen McCallie helps make a waterproof tent to keep Mike Bullivant and Mike Leahy dry on their overnight expedition in search of gold-bearing rock. And Kathy Sykes and Jonathan Hare make a seismograph using alarm clocks to measure earthquake activity in the area.
Ice Presenter Kate Humble takes the Rough Scientists away from their epic quest for New Zealand gold this week, to set them one of the series toughest challenges yet. The team must measure the speed and melt of the Franz Josef Glacier, an awesome seven miles of ice. In addition, the scientists have to keep themselves warm on the ice without lighting any fires, which involves building an ice lens and generating chemical heat. With just a basic toolkit and the island's natural resources at their disposal, the team must draw on their pooled ingenuity and scientific knowledge to complete the tasks.
Treasure Hunt The Rough Scientists step up their search for gold. The deadline is looming for Kate Humble and the five 'Rough Scientists', who must find and extract enough gold to make a souvenir of their stay in New Zealand's south island. As the tension mounts, Kate sets three tough challenges to extract gold from rock and sand, to build an altimeter and to use it to find buried gold from a treasure map.
The Big Smelt It's D-Day for the Rough Scientists who must build a furnace and bellows so they can try to smelt the gold they have collected. To turn their powdered gold flakes into a solid nugget they have to reach a white-hot 1062 degrees Celsius.
