Global warming â the steady increase in Earthâs air and ocean
temperatures since the mid-20th century â is one of the most discussed
and studied topics in the scientific community today. This kit
introduces you to Earthâs climate and the issue of global warming with
23 hands-on experiments. Since Earthâs formation, its climate has been
constantly changing. Periods of warmer climate have alternated with ice
ages. These changes happen over long periods of time. During the last
few decades, a warming in the climate has been observed everywhere on
Earth. While some warming may be due to natural phenomena, scientists
predominantly attribute global warming to human influence. This kit
gives you the basic knowledge you need to understand the climate, why it
changes, and how our actions affect it. First, learn about Earthâs
climate system, weather, and atmosphere by conducting experiments with a
model Earth and atmosphere. Explore the hydrological cycle to learn
about humidity, clouds, and precipitation. Model Earthâs heat
reservoirs, thermals, global and local winds, and ocean currents. Next,
learn how human activity influences the climate with experiments
involving carbon dioxide and the greenhouse effect. Measure the effects
that increased levels of carbon dioxide have on the temperature of air.
Learn about how warming affects the Gulf stream. Finally, investigate
the potential consequences of global warming on humans, ecosystems, and
the worldâs economies. Learn what we can do to protect the climate. The
full-color, 48-page manual guides your experiments. Ages 10 and up.
