Students explore Weather Instruments with twelve hands-on activities and the Delta Science Reader. They measure weather conditions using kit tools and devices of their own making. Observations begin with temperature. Students compare Fahrenheit and Celsius scales and take thermometer readings twice a day. They investigate air pressure and barometers, and construct wind vanes and record wind direction and wind strength. Experiments with evaporation and condensation lead to humidity tests, cloud classifications, and indoor precipitation. From their own data, students draw conclusions about connections among the weather factors. They learn how and why today's factors reliably predict tomorrow's weather.
In the Delta Science Reader Weather Instruments, students read about what weather is and what factors cause changes in the weather. Various weather tools, such as the thermometer, barometer, wind vane, anemometer, hygrometer, and rain gauge, are described. The book presents biographical sketches of key scientists in this field, Gabriel Fahrenheit, Anders Celsius, and Sir Francis Beaufort, and describes the work of airport meteorologists. Students also read about wind chill and how a thermometer works.
