Precipitation is water that falls to the earth in the form of rain, snow, sleet or hail. A precipitation gauge is used to measure the amount that has fallen. We should take time at the beginning of each period for about one week to measure these weather elements. Rotate the responsibilities of each group and check your results with the weather channel if possible. Use your bulletin board to post your information so each class can compare their results as each is taken at a different time during the day. You might want to use a chart similar to the one you will see on the next page.
Assign each group a research activity of finding weather conditions over the past year. Each group could do about a two month record. You might also want them to do a gnomon measuring shadow lines at various times of the year to show the sun’s elevation. This information can be found in the Interaction of Earth and Time text by Rand McNally.
