A sense of wonder, of curiosity, of inquiry and the energy and eagerness to pursue the "Why" and "What" of everything, are what make young children scientists. Children need to explore the world around them by observing, listening, squeezing, pouring, and having "hands-on experiences" with science. We organized our class activities around inquiry into rain and where it comes from and how to turn it from impure to potable. KGI students in Ain Aar came out with different hypothesis, and we conducted and tried out most of them. Then we watched a documentary on YouTube to find out that the best way to have drinkable water is to boil, strain it and expose it to sunlight. Our focus on rain provided an opportunity to notice what is happening in the world outside; more and more of the children are becoming aware of the changes that are taking place in their world!
