Have you ever wondered what happens after you press submit on your International Virtual Science Symposium (IVSS) report? The GLOBE Implementation Office (GIO) Education team gets to work! Ok, that might be a little misleading because work on the IVSS already started back in August when we started planning for the 2021 IVSS. And while learning about planning webinars and recruiting judges might be something you are interested in; this is not what this blog post will cover. This is the “story” of what happens after teachers upload their students’ projects and press the big blue ...

Whenever you submit a cloud observations, the GLOBE Clouds team at NASA Langley Research Center looks for satellites that were over your area at about the same time. The team then gathers the information from these satellites and compares them to your own observations. The result is a satellite match table that you receive through an email!    The table allows you to compare what you saw and what the satellite noted. You also have the actual satellite image at the bottom of the table! A new "How to Read a Satellite Match"  page is available for you to learn ...

Today we start a series of posts devoted to providing information, tips, tricks and answers to frequently asked questions by Calitoo users! So, how do you measure Aerosol Optical Thickness (AOT) with a Calitoo? First and foremost: NEVER look directly at the sun! And… ONLY take measurements when the sun is not obstructed by clouds. TIP: Use your hand(s) to cover the sun; if you see any clouds on either side of your hand(s), do NOT take any measurements. Wait until the sun is not obstructed by clouds. Now, the Calitoo sun photometer measures AOT values at 465 nm, 540 ...

A fourth grade student from Public School 122 (Queens, NY), recently visited NASA Langley for a week. During his visit, he studied the GLOBE Aerosol Protocol. He went outside the Atmospheric Sciences building and collected aerosol data using a Calitoo sun photometer, which measures Aerosol Optical Thickness (AOT) at three wavelengths: 465nm (blue), 540nm (green) and 619nm (red). After downloading the data measured with the Calitoo to his laptop, the student learned how to access AERONET data. The AERONET ( AE rosol RO botic NET work) project is a federation of ground-based remote ...

Gathering data Once you have determined what protocols to use for your project, you will need to develop a plan for gathering the data. It might consist of using automated data collection or making your own measurements. Also, it may include finding data taken by others, such as when you compare your observations with those of another GLOBE school. Automated Data Collection If you are using an automated data collection device or devices, verify that the data are being recorded properly before your official testing timeframe. You will want to monitor that the data are being ...

By Claudia Caro  and Erika Podest  Curiosity is a natural characteristic of all people, especially the young. It is the first step for a child to build knowledge, and I am sure we can all remember as children asking what?, why?, where?, and numerous other questions as we tried to learn new things. Unfortunately, as children grow up, this natural curiosity slowly fades. Why is this? We don’t exactly know, but it might be that as children grow older they think they know all the answers or because most school systems are structured to teach by providing answers rather than ...

When you start writing your GLOBE report for IVSS, it might be difficult because you might not sure where to start. We tend to start writing the Methods section first because it is something you did it yourselves and it should be relatively easy and straight forward to write. Second, you should write the Results section, do graphs, tables and texts (think of a best way to present your cool data to the whole world). Third, you should start writing the Introduction stating your hypotheses and predictions. The next step would be the Discussion section. It is funny to say but as scientists, ...

Quaking aspens can grow in a wide range of environmental conditions. They can tolerate a wide variety of variations in climate and environmental conditions including slope, moisture, surrounding vegetation, and soil ( https://www.fs.fed.us/wildflowers/beauty/aspen/ecology.shtml ). I found this information with a simple web search. But, before there was access to infinite articles, websites, and papers all a click away, scientists had to figure out growth trends using data. So, before I decided to do a web search about the environmental conditions of aspen habitats (my memorized aspen ...
