If you are a hiker or camper, you may have heard about Vestergaard Frandsen’s LifeStraw. It’s a hollow stick equipped with a series of filtering membranes. You put the end of the stick in a river or puddle ─ or a toilet, for that matter ─ and suck on it. By the time the water hits your lips, it is clean and safe ─ its filters are fine enough to trap virtually all bacteria, viruses and parasites. The product has a bigger cousin called the LifeStraw Family. You hang it on your wall, pour dirty water in the top, open the tap and clean water comes out the bottom. No power or replacement parts are required. Each unit cleans about 18,000 liters of water ─ enough for a family for three years. The market cost of the unit averages out at a penny per ten liters of water purified.
Vestergaard Frandsen will distribute the LifeStraw Family for free. It is helping to sponsor a traveling campaign through the western part of Kenya set for April, 2011, that will reach 4 million families. The campaign bundles various products ─ each family that attends will get insecticide-treated bednets to protect against malaria, AIDS tests and counseling and a free LifeStraw Family.
Louise Phinney on 03 Apr 12Somewhere between kids' intuitive social savvy and their online behavior lies an opportunity for both parents and educators to teach responsible digital citizenship, and there are plenty of organizations dedicated to this task alone. Define the Line, a project of McGill University in Canada, was recently awarded a digital citizenship grant by Facebook to help further its work in creating materials to open dialogue about finding the line where joking crosses into negative or criminal behavior. The site includes videos and scenarios designed to enhance discussion of real-world digital topics. Common Sense Media recently launched a free digital citizenship curriculum categorized by age. The curriculum includes both paper-based and digital activities and teaches online safety and Internet research skills in combination with ethics.
