SNOWBALL.  Śnieżna kula jest metodą dyskusji. Charakteryzuje ją to, że uczniowie najpierw samodzielnie opracowują problem, później jego rozwiązaniem zajmuje się grupa, a ostateczną decyzję, w ramach podsumowania dyskusji, podejmuje cała klasa.

First children work in pairs. They discuss the problem and write down their settlement. Then they work in groups of four. They discuss the problem again and also write down their settlement. It takes time, as children want to convince friends to their rights. After a while students work in groups of eight and after writing down groups’ settlements all class work with the teacher and establish common point of view. Students make a poster and show it to friends.
 * The problem – How to save water ? **



Verify that your home is leak-free. Take shorter showers. Use the minimum amount of water needed for a bath. Don't let water run while shaving or washing your face. Turn off the tap then brush your teeth. Use automatic dishwashers and clothes washers only when they are fully loaded. When washing dishes by hand, fill one sink or basin with soapy water. Never put water down the drain when there may be another use for it such as watering a plant or garden, or cleaning.

**By calculating your water footprint,** you can find out how much of the world's water resources are consumed by your way of life. Even though there is still plenty of water in most of the Western countries, many of our daily products contain virtual or hidden water. Virtual water may have been consumed in countries where water is scarce. For example, one cup of coffee contains up to 140 liters of virtual water used in the production! Your water footprint reveals not only the water you use directly (in washing, for example), but also the amount of virtual water you consume. By measuring your water footprint, you will receive information and useful tips to support your choices.
