Does your family like collecting weather data? Are you collecting cloud and temperature data? You're ready to collect more weather data. GLOBE's Atmosphere Investigation form has students collect temperature, barometric pressure, relative humidity, precipitation, and clouds. I like the data sheet. You can print one, attach it to a clipboard and head outside. Okay, send the kids outside. This form includes the main factors needed to follow the weather.
Let's build a sling psychrometer to measure relative humidity. Surprise! GLOBE has a protocol for relative humidity. Now that your family is collecting a wide variety of weather data on a regular basis you may want to build the instrument shelter and invest in a maximum minimum thermometer and try your hand with the maximum minimum temperature protocol using the field guide, data sheet and referring back to original current temperature protocol, without crying. GLOBE indicates that data should be collected within one hour of solar noon. Remember, the GLOBE program is international and has strict protocols. Here GLOBE explains the measurement times.
GLOBE offers a challenging program with detailed (bordering on obsessive) field protocols for EVERYTHING. But, where can you go and find a similar program of this caliber free?
