To help teachers welcome students back to school, as concerns grow about this flu season and the H1N1 2009 flu virus spreads, The National Education Association Health Information Network (NEA HIN) and The Clorox Company are offering a free coupon for Clorox® Disinfecting Wipes to teachers nationwide.

September 2 through September 5, 2009, teachers can visit www.CloroxClassrooms.com to redeem the offer, while supplies last.

Healthy habits, like hand washing and disinfecting germ hot spots are critical steps to help prevent the spread of germs that can cause illnesses, like flu.

At the Web site, teachers can also download a free “Clean Up the Classroom” kit, including lesson plans, games and other tools to help reduce the spread of germs at school.

To mark ESA astronaut Frank De Winne's six-month OasISS mission to the International Space Station, and triggered by his role as goodwill ambassador for UNICEF Belgium, ESA's Human Spaceflight education team has teamed up with UNICEF to launch an online quiz for 12-14 year old European children.

The theme of the quiz is water on Earth and in space. UNICEF is currently running a campaign called WASH about water and hygiene. The campaign centres on the importance of clean water for human life.

Water, as a primary element supporting life, is also of paramount importance for human spaceflight and future exploration endeavours. Considerable effort is being made to help resolve the specific problems encountered in space – such as water scarcity, the need for recycling and special hygienic conditions. The technologies and solutions developed to meet these challenges are directly applicable on Earth.

By participating in the ESA/UNICEF water quiz you can find out more about water on Earth and in space and learn how the two are related.

At the end of the quiz, Frank De Winne will reveal the answer of the final question and announce the winner of the competition from on board the International Space Station. The inflight call will be broadcast during the ISS Day, an education event scheduled to take place in Brussels, Belgium, on 6 October. A recording of De Winne's announcement will be available on the ESA website a few hours after the event.
