Reading this book has shown me that simple is way stronger than complicated and while it's not directed at presenting to children, I'm sure children would be even more appreciative of simple. There's this mistaken belief that simple is ... well ... simple. But let me borrow a quote from the book that's by Leonardo da Vinci. "Simplicity is the ultimate sophistication."
So I'm going to go back over the powerpoint I've prepared and will focus on keeping it simple.
