NASA Community College Aerospace Scholars (NCAS) is a fully funded, STEM-related program that is sure to get educators' attention. The opportunity begins with a five-week online learning experience that uses the past and present of Mars missions to elucidate math, science, and engineering quandaries. Participating students then go on-site for an all-expenses paid workshop at a NASA center. Even for students who don't apply to the highly competitive program, however, there are some wonderful resources on the site. The Features section, for instance, hosts portraits of eight student-scholars who completed the program, telling the stories of how they came to the program, and what they did afterward. In addition, under the About NASA and JSC tab, readers can find links to NASA centers around the country, including the famed Lyndon B. Johnson Space Center in Houston, Texas and the Jet Propulsion Laboratory in Pasedena, California. [CNH]

This site from the National Archives is designed to provide educators with primary sources about the struggle for rights in the United States. However, any reader with an interest in American history will find much to ponder here. In the Teaching Activities section, educators may choose from two dozen compelling classroom activities on topics that run the gamut from The Civil Rights Act of 1964 and the Equal Employment Opportunity Commission to the Integration of the U.S. Armed Forces to the Assimilation of American Indians. The Primary Sources by Topic section provides fascinating original documents, photographs, and other paraphernalia on a range of topics. It's a wonderful way for educators, students, and the generally curious to engage with primary sources related to Citizenship, Free Speech, Americans with Disabilities, Immigrants, and more than a dozen other topics.

As the Edutopia site notes, "High-quality teaching is vital for student success." Created by the George Lucas Educational Foundation, this section of the Edutopia site presents readers with a plethora of information on Teacher Development. Educators, as well as anyone interested in the art and science of good teaching, may like to begin with the Overview section of the site. Here, a short introductory video lays the groundwork for growing great teachers. Moving on, the article "Why Is Teacher Development Important?: Because Students Deserve the Best" (which can be located under the Importance tab) provides an introduction to the tools, mentorship models, and experiences that help prepare teachers for the classroom. The Research tab is another great addition to the site and delivers a review of research with generous links to other articles, both on and off the Edutopia site. A number of Teacher Development Videos, which can be viewed free of charge, and a discussion board round out the site. [CNH]

June is Immigrant Heritage Month, and this site is alive with stories of America's diverse citizenry. Readers may view uploaded videos, tweets and retweets, photographs, inspiring quotes, and, above all, the many, many stories of those who have come to America looking for a better life. Some of the stories, such as a Vietnamese man's first encounter with snow, are humorous; others, such as children of immigrants recalling their parents sacrifices, are touching. Overall, the site has an almost overwhelming ability to convey the complexity and depth of the American immigrant experience, in many of its varied forms. Educators may find the site useful during lesson plans on immigration and the diversity of the United States, while other readers may just enjoy the wealth of narrative available here. [CNH]

Completing Free Code Camp is no easy task. In fact, students log over 1,600 coding hours by the time they complete all the classes, tasks, and projects that the site employs. The upswing, however, can be significant, as the site promises that committed users will: learn full stack JavaScript; build a portfolio of real apps that real people are using; and, hopefully, get a coding job. Users begin by taking 200 hours of online lessons. Next, they log 200 hours of JavaScript Algorithm practice, then work on 200 hours of front end web development, followed by 200 hours of full stack web development practice. Camp is then rounded out by 800 hours of real-world web development work for participating non-profits. Along the way, users connect with other "campers," and learn applicable skills. An email address or social media account (e.g. Facebook, Twitter, etc.) is needed to create an account, but the site is well-organized, user-friendly, and, best of all, free. [CNH]

Perhaps one of the defining features of Book Riot, the online book review site, is its indifference to the distinctions between "highbrow" and "lowbrow." Here book lovers will find intricate perlustrations of 19th century French dramatists next to peppy lineups of the best summer beach reads. Genres covered include Children's, Classics, Feminism, Poetry, and over a dozen others. With more than 20 unique columns, readers can browse musings on the week's most exciting books (Fresh Ink), view thematic selections from select authors (Reading Pathways), or even participate in The Ultimate Book Trivia Challenge (Quizzes). The site even offers its own weekly podcast, with a backlog of over 100 episodes at the time of this writing. In addition to all of those enticements, the site donates two percent of its revenue to literacy-related nonprofits. [CNH]

The New York Public Library's Irma and Paul Milstein Division of United States History, Local History and Genealogy boasts a collection of over 80,000 original photographs of New York taken between the 1870s and 1970. This site gathers many of those images together into a dynamic online map outfitted with red dots. Readers may zoom in, zoom out, and click on the dots to find photographs drawn from particular geographical locations, thereby witnessing the changing landscapes of New York City over a period of nearly a hundred years. For instance, clicking on the dot that corresponds to East 42nd Street and 2nd Avenue in Manhattan calls up over a dozen images from a number of decades, including a 1920 shot of the 3rd Avenue elevated train, which was eventually closed in the 1950s. Any photograph of interest can be explored in grater detail in the NYPL Digital Collections. [CNH]

·http://www.ted.com/talks/renata_salecl_our_unhealthy_obsession_with_choice

The idea of choice has been elevated to an ideal of nearly religious dimensions in the United States and other Western democracies. But is there a dark side to the ideology of choice? Renata Salecl, the Slovenian philosopher and social critic, thinks there is. In this talk, Salecl draws from fields as diverse as sociology and psychoanalysis to problematize the unexamined promotion of choice. In fact, in the course of 15 minutes, she argues that our choices are seldom rational; in fact, an overabundance of choice is anxiety provoking, and, perhaps most provocatively, the ideology of choice actually blocks us from becoming productive and powerful agents within democratic societies. Whether or not one agrees with the critique, the talk certainly makes one think about the intricacies of choice. [CNH]

The Acadians, French-speaking settlers more commonly known as "Cajuns," first took up residence in what is now Eastern Canada's Maritime provinces, part of Quebec, and present-day Maine in the 17th century, only to be driven down the coastline to Louisiana by the British. Readers may find a long article about the "Acadians" under "A-Br" in the Multicultural America section of EveryCulture.com. Laid out in alphabetical order, the site also offers detailed information about Apaches, Hmong Americans, Slovenian Americans, and many other groups. The articles are well-written, offer rich information on a range of cultural practices and histories, and usually culminate in a number of resources for further inquiry, such as lists of newsletters, magazines, newspapers, and websites.

·http://www.nationalarchives.gov.uk/latin/beginners/

For anyone interested in reading official documents written in England between the years 1086 and 1733, knowing Latin is often a necessity. And not just any form of the language, but the particular version of Latin used in those documents, which differs from classical Latin in significant ways. Thankfully, the National Archives of the United Kingdom has launched a practical online tutorial for beginners in this uniquely British dialect of the ancient tongue. On the site, readers may link to explanations of the language and read about classical Latin. They may also, of course, engage in the free Tutorial, which starts with a lesson on verbs and ends, eleven sessions later, with a 5-stage lesson on adverbs, numbers and dates, months, useful phrases, and dating clauses. Each lesson includes practice sentences and at least one activity. Best of all, once readers finish with Beginners' Latin, they can move on to the equally exceptional Advanced Latin, also on the National Archives page. [CNH]

One of the ways that the Digital Public Library of America (DPLA) showcases its growing collections - DPLA hit ten million items in April 2015 - is through exhibitions. This Land Is Your Land presents materials from several DPLA contributors, including Clemson University Special Collections, Yellowstone National Park, and Great Smoky Mountains National Park. The images are organized into 6 themes: Building the Parks, Interpretation of Parks, Landscapes, Protecting the Parks, Stewards of the Parks, and Wildlife and People. Several of the themes include sub-themes; for example, first select Stewards of the Parks to access the landing page for this fascinating sub-collection. From there, use the "Next" button to move on to The Stewards of History at Andersonville National Historic Site sub-theme for individual and group shots of rangers at Andersonville National Historic Site, a park that is located on the grounds of Camp Sumter, a Civil War prison camp. Visit the From Superintendents to Assistants sub-theme for a few photos of some of the other staff in National Parks who are not park rangers, such as superintendents and their secretaries. [DS]

Google Gives Gmail Users the Ability to 'Undo Send'

How to Unsend Emails in Gmail
http://www.wired.com/2015/06/gmail-undo-send/

It seems that everyone has, at some point, sent an email that they immediately regretted. Whether it was "replying all" when the information was meant for just one person, or writing something harsh and then thinking better of it, who hasn't wished they could reach into their computer and take back their words? Well, now Gmail is giving its users that chance - sort of. Google unveiled its new "Undo Send" function this week that, in fact, offers email correspondents a precious, if short, window after sending an email to cancel and rewrite. How does it work? Users need only turn on the function in their settings, choosing a "cancellation period" of five, 10, 20, or 30 seconds. Then each time an email is sent, an unobtrusive pop-up appears offering the option to "undo." Clicking on the icon reverts to the original email, where the author may tinker at will. [CNH]

The first three links, from the Guardian, BBC, and Forbes, offer coverage of Gmail's roll out of the 'undo send' feature, which has been available through its Labs section for six years, but only became a standard feature this week. Next on the docket, Gizmodo's Matt Novak offers some advice about the feature: "Turn it on." In addition, an article from the Wall Street Journal's tech blog features a handy screenshot of what to look for in the Gmail settings when scrolling for the new feature, and Megan Logan, writing for Wired, offers some simple, step-by-step instructions for how to turn on the feature.
