Sink or float: Explaining it like a scientist

Today we decided whether various items would sink or float. We discussed together how the objects felt, their shape and their weight. We talked about what each object was made of - paper clip, styrofoam, paper cup, plastic counting bear, pencil, Popsicle stick, coins, magnet, foam shape, rubber ball, straw, toothbrush, wooden block and several more. We talked about how scientists ask questions, formulate guesses and test their results. Each child made their prediction before dropping their item on the side of the container they believed it would fit - floaters or sinkers. I love to listen to their descriptive explanations telling if they were "right" or "wrong". We talked about how the wrong guesses are important because they help us discover the right ones!  Fun day :)
