Water play & music exploration - Child's Play Music. This is wonderful for PreK/ K exploration! The point is to let them discover on their own, and eventually to scaffold (or guide) your students into making new discoveries. "What else could you do with this lid to make a different sound?" "I wonder what would happen if..." "What kind of sound did that make?" "Which worked better?" You'll be amazed at what they come up with and the language they use to explain their process.
