Infographic: Sorting Through Our Space Junk – World Science Festival

This infographic provides some insight into the litter we have scattered over space over the decades. Space junk, which scientists call orbital debris, poses direct threats to satellites and spacecraft. For instance, the International Space Station has to sidestep dangerous pieces of trash and satellites regularly factor in debris when deciding on a launch date. The countries that explore space are trying to find ways to clean up the mess before the clutter makes launches impossible. In the meantime, it’s helpful to know what’s up there.By: Julie Rossman and Roxanne PalmerSign up for our free newsletter to see exclusive features and be the first to get news and updates on upcoming WSF programs.

STAO’s Twitter Professional Learning Network (PLN)

With the gcool tabletrowth in technology and social media, teachers have realized that they can connect with other professionals beyond the walls of their own school through Twitter, Facebook, Google+, Instagram and can curate (and find) resources on Pinterest.

Edublogs has a great definition of PLNs.  Click here…

The Personal:

Having a PLN is about making connections and building personal relationships with teachers, school administrators, university professors, and experts around the world. No matter where you are in the world, there’s always someone online available to answer questions, share their expertise, and simply chat about what’s happening in their lives and classrooms.

The Learning:

Having a PLN is about sharing ideas and resources, collaboration, and learning. We may share our learning, ideas and expertise in different ways; using different media and tools, but the essence is the same: the PLN is simply the best professional development you will ever participate in – and it’s available 24/7.

The Network:

The defining feature of the PLN is that it is a global learning network, enabling people to tap into and share diverse, global perspectives on teaching strategies, educational issues, and technologies. If takes time and effort to build these connections, but it’s well worth the effort.”
