Two great new posters are now available for you to download.The first, produced in collaboration with the United States Geological Survey, shows how the Water in Nature is always the same amount in a constant cycle, and another, an infographic on Water Cooperation, shows how we use, and sometimes abuse, water around the world.

A question and answer game for your classroom produced for World Water Day 2012. Print out the PDF file on your printer. The teacher holds up a food card and members of the class or audience guess how much water is needed to make up that commodity. The closest to the actual amount is the winner of that round. The winner of the most rounds wins the game. Certificates are also included in case you want to reward the winners of the game.

To produce food, water is consumed by the plants in the field through evaporation and transpiration. The amount of water needed varies with crops and depends from place to place, on local productivity and conditions of available water supply through rainfall or irrigation. Once the product is harvested and becomes available on the market, the water embedded in the product changes status from ‘real’ water to ‘virtual’ water. In this poster you can see how much water is "embedded" in each product and discover how much water is needed to produce it.
