 Hi, I want to tell you one way that I introduce the concept of water as an element that are characteristic of all living things, a need of the human experience for sure. When working with four to six year olds, children don't really understand, especially if they are in a place where water is not difficult to find, for them to comprehend that there might be places where people can't find good water and what does that mean? For four to six year olds, it's really hard to explain that. So what we can, though, talk about is that it's a human basic need and it's also a source of joy and comfort and beauty. And I want to introduce that to students with a book called A Cool Drink of Water. And I think I'm going to go ahead and read this to you because it's so quick and the pictures tell you far more than what I can explain. Somewhere right now, someone is drinking water, scooped from the river, drawn from a well, caught as it drips from the roof, everyone, everywhere, a nice, cool drink of water. And in this book, there's a nice resource for the connection to the locations geographically of the photos, which were beautiful in this particular book. It's a starting point for lots of conversations, but I think when you're talking with four to six year olds, you have to talk to them from their point of reference and ask them where they get their water, where does it come from. You could extend this to why is it important to conserve water, to take care of the amount of water that we use and the daily activities that we have. So this is a discussion starting point and you would springboard other activities off of it.
