CLIMATE AND WEATHER
Investigate specific weather phenomena
Build a model of Earth and its atmosphere and then use it to conduct experiments that show how the global wind system works. Trace air currents from the icy cold poles to the warm equator and back with a wisp of smoke. Model Earth's heat reservoirs, thermals, and global and local winds. Recreate ocean currents in a small basin of water. Simulate Earth's rotation and revolution to learn how the sun affects the weather daily and seasonally. Learn about the climatic zones and the composition of the atmosphere. Experiment to see how carbon dioxide levels affect temperature. Explore the hydrological cycle to learn about humidity, clouds, and precipitation. Build a simple barometer, set up a rain gauge, and track the temperature. Full-colour, 48-page manual.
