What child isn't curious about why they can see their breath on a cold day, where rainbows come from, why ponds freeze in the winter, or what causes thunder and lightening? This book answers these questions and more, using projects which clearly demonstrate how and why various phenomena of weather come about, such as how the seasons affect temperature, how moisture gets into the air and how clouds and precipitations form. Students learn why breezes from the sea are cooler, how air pressure and humidity affect our comfort, how weather is predicted, how wind currents form, and more. Wood also shows readers how to build and use thermometers, wind and rain gauges, a barometer, a humidity indicator and other weather instruments.
