Ask the children to walk around the classroom and grab one item that can fi t in the palm of one hand. Have a large, clear tub of water in the center of the group. Provide a large chart with two columns labeled “Sink” and “Float.” Allow the children to experiment to see whether the item will sink or float. Have each child drop in the item and chart if the item sinks or if it floats. After all the children have taken a turn, ask them to go find additional objects. This time, ask the children to predict if they think the new item will sink or float based on what they just learned. Ask the children questions such as, “Why do you think the pencil will sink?” They may answer, “because the pen did.” Chart their predictions.This could be done in large group.
