"How many islands are in Rhode Island?"
Global news with a spatial perspective: Interesting, current supplemental materials for geography teachers and students.

I recently received this question and immediately thought that this is a great geographic question, but one that geographic tools can be used to find the answer. I downloaded all the Rhode Island toponymns (place names) listed by the United States Board on Geographic Names and filtered out all the listed Islands (108 is the answer!!). A spreadsheet of the data didn't help to visualize this data so I created this interactive map. Only 1 of the locations didn't have coordinates, some are scarcely more than rocks, and this is only according to the the U.S. Board on Geographic Names, but this is the most complete map of islands in the state of Rhode Island that I could produce. Additionally, here is an article about some sailors who sought to explore every island of the Narragansett Bay.
In New Hampshire they are doing great work to make mapping data useful in the classroom. This site is one that they use to show how students can map locally relevant data from an online data set. CoCoRaHS (Community Collaborative Rain, Hail & Snow Network) is a crowd-sourced network that gathers North American precipitation data. The data (especially the total precipitation summary) can be easily copied into as spread sheet and saved as a CSV file (which can be uploaded to ArcGIS online).
"By 2025, the developing world will be home to 29 megacities."
Through this interactive mapping feature with rich call-out boxes, the reader can explore the latest UN estimates and forecasts on the growth of megacities (urban areas with over 10 million residents). These 'cities on steroids' have been growing tremendously since the 1950s and present a unique set of geographic challenges and opportunities for their residents.
Download the data yourself as a CSV file and your can import this into ArcGIS online and symbolize your map with any of the columns in the dataset.
