Age: Elementary and upTime: 2 hours or moreType of Activity: Backyard science Materials needed:
Thermometer: To record temperature.Rain Gauge: To measure rainfall.Wind/Weather Vane: To record wind direction.Barometer: To measure atmospheric pressure.Anemometer: To measure wind speed.Psychrometer/Hygrometer: To measure relative humidity.Journal: To record your readings and data.
A Few Notes on Record-Keeping: Decide which weather events and data you want to record and how oftenyou want to take measurements (once a day, twice a day, etc.). The moredetailed and accurate your measurements, the more specific your picture of the patterns will become. A ruled notebook or ledger is an ideal place to record the measurements. Listmeasurement types down the side (one event per line) and print the datesacross the top to create a simple grid sheet. Hint: Numerical data can also be entered into asimple spreadsheet-type program and manipulated to create impressivevisual charts and graphs to display data. Your kids can also take a crackat creating a wall chart to create a stunning data display. It would make a great science project or extra-credit work in any earth science course.
