You can find your own directions to make any of the following weather instruments.
At the end of this message you will find more links to some places that I found with good directions. The ones found here are not your only sources.
Barometer (15 points)
Thermometer (10 points)
Anemometer (10 points)
Anemometer with wind vane (12 points)
Rain gauge (2 points)
Hygrometer or Psychrometer (8 points) + 2 more points for calculating the dew point and cloud base elevation.
After you finish building the weather instrument, you must validate it.
To do this, calibrate the instrument so that you know how to use it to obtain real data.
Then, take three separate readings at three different times (preferably on different days).
Compare the data you got with the actual weather conditions located here and here (check both!) Calculate your percent error for each of the three trials. This percentage is a measure of the accuracy of your instrument. You must turn this information in with the instrument you built by Friday, June 5.
