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.
Explore
the science
 The
scientists begin by trying to find the best waterproofing
agents for a tent,
and look at the possibilities for insulating it. They also
build a seismograph
and test it with dynamite explosions. The Rough Scientists
have explained the science behind these challenges.
 What
makes a good waterproofing
agent? Discover how material can be treated to repel water
and what modern tents are made of.
How does
a seismograph
work? Investigate the physics and find out how to make one
for yourself.
Diaries
With
all this earthquake activity going on around them, were the
Rough Scientists quaking in their boots? Did the two Mikes
get rained on and manage to stay dry in their newly waterproofed
tent? Find out what each scientist felt about their mindbending
challenges by reading their own personal
diaries.
