Wayne,
I agree with you about Tim Flannery’s book—it’s great. You’re also right
about the many simple science experiments and demonstrations to illustrate
climate change. I urge you to visit the IGLO (International Action on
GLObal Warming) web site: www.astc.org/iglo to have a look at our extensive
Toolkit containing the demonstration you describe and many more such
activities and demonstrations that can be done in science centers and
classrooms to educate citizens of all ages about the effects of global
warming. As ASTC’s first international initiative, IGLO involves science
centers and museums all over the world in producing activities and
demonstrations like these and providing content to enrich the Toolkit. On
the web site, you’ll also find current news about IGLO and climate change
and descriptions of what’s going on at other science centers.

I've almost completed Tim Flannery's terrific book The Weather Makers on
the subject of global warming. As I read it, I kept thinking there are
some really simple and basic science ideas here. Maybe there's a
possibility of creating some simple demos and exhibits at our small museum.
A really simple one that might make a good demo is to demonstrate how
Arctic ice is less dangerous to increasing ocean levels than Antarctic
ice when it melts. Here's the demo. Two clear cups are filled with
water part way to the same level. One has a rock on which an ice cube
sits. It represents the Antarctic. The other has an ice cube floating in
water, and represents the Arctic. Let them melt (encouraged by a hair
blower.). When they melt, the water level of the Antarctic cup will be
higher than the other. Simple science, but I wonder how many people
think of this when hearing someone talk about rising ocean levels from
melting ice. (Of course, the water level in the Arctic cup hasn't changed.)
