23 Hands-On Activities
The steady increase in Earth’s air and ocean temperatures since the mid-20th century has warranted much concern and controversy. With this kit, you will complete a series of experiments that demonstrate how our climate works, why it changes, and what actions affect it.
Model Earth’s heat reservoirs, thermals, global and local winds, and ocean currents; measure the effects that increased levels of carbon dioxide have on the temperature of air; investigate the potential consequences of global warming on humans; and much more. The 23 experiments also reveal what we can do to help our environment. Includes a full-color, 48-page manual. Recommended ages 10 and up.
