Sink or Float
Help Grover figure out which items sink in water and which float, and talk with kids about which items sink and which items float, and why that might be.
Help kids play the sink-or-float game with Grover. Talk with kids about which items sink and which items float, and why that might be.
Then, do your own sink-or-float investigation with toys, food storage containers, and bottles of shampoo. Make a hypothesis, a thoughtful guess or possible explanation, for why something happens about which item will sink or float, then try it out! You might draw pictures of each item in a chart that shows your findings.
What else can you investigate? Start by looking around your home and asking the question, “What do you think would happen if…?”
