In order to find recommended age and/or grade ranges for each protocol, go to: www.globe.gov and click on "Do GLOBE" tab -> "GLOBE Teacher's Guide" link -> under the right-hand column heading "Implementing GLOBE in the Classroom" select "Tool Kit" -> Scroll down to page 19: "GLOBE Measurements and Their Instruments." This table will list the appropriate age levels recommended for taking each GLOBE measurement. Several measurements will say "ALL" because they can be tailored by the teacher to fit the needs of their students.
In order to see the requirements to qualify for the GLOBE Science Honor Roll, please go to Honor Roll Specifications.
For atmosphere observations, you are able to take data measurements anywhere within 100 meters of your weather station location. If you are going to take measurements from a distance further away than that, then you need to define a new site. You should always take new GPS readings for each new site, as they may be slightly different.If your study site is too far away, you may get a "warning message" about the distance, but your data will still "count" and you will get the "smiley faces" when you submit the information.
