New Nonprofit Partners Weigh in on Dating Violence, Teach You How to Get Your Bike on A Bus

Here's what's been going on in the world of YouTube Nonprofits since we last spoke:

* Do Something released this video to raise awareness about the fact that 1 in 3 teens are abused in a relationship, after a New York Times article about Rihanna and Chris Brown's domestic violence incident quoted teens saying that dating violence wasn't a major issue. The video has received over 500,000 views and according to DoSomething's Chief Technology Officer, the organization has gotten close to 250,000 requests for dating abuse awareness bracelets.

* The Iowa Bicycle Coalition aims to educate citizens about the importance of bike safety and includes a number of helpful how-to videos like how to load your bike onto a bus and how to choose the right type of bike for you.

* Architecture for Humanity, citing the World Bank statistic that educating all children worldwide will require the construction of 10 million new classrooms by 2015, is inviting teachers, students, architects and designers to work together to design the classroom of the future. The ideal design will provide smart, safe and sustainable learning spaces for children.

* Special Olympics International has just launched a new "End the R-Word" campaign to end the use of the word "retard." This campaign video features various teens talking about how the word is offensive and needs to go.
