A weather station is a set of devices for measuring elements like temperature, rainfall, wind speed, and pressure. You can buy these devices in your local hardware store, or you can make them from scratch using common materials found around the house.
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.
