Observation and measurement are the first important steps of any scientific study. Young students can learn about and develop their observation and measurement skills by measuring the amount of rain fall in their area in different days and months of each year or part of the year. All you need is a rain gauge that is an open-top graduated container as well as your notebook and a pen.
This rain gauge can measure the amount of rainfall in both Metric(Millimeter) and English(Inch) units. Contains two graduated containers, one for mounting or hanging on a pole (1.5"x1.5"x9") and the other (1.5"x1.5"x2") for inserting in the ground.
Rain gauge is also a beneficial tool for every lawn allowing you to see if your lawn has received enough rain or you need to water your lawn.
In warm weather your lawn needs water if the rain meter reads less than 1".
