Sequencing Activity
Students watch a demonstration of heating a flask that is capped with a rubber stopper and glass tube and partially filled with water. They watch what happens when it is inverted into a beaker of water. Water in the beaker rushes up and into the flask. Why? Students arrange pictures of the experiment in sequence.

It is useful to organize observations into a sequence of events. Observations can be ordered using a series of pictures or written observations.
Communicating is one of the fundamental scientific thinking processes. Recording observations, ideas, and questions in writing, and representing observations by a series of diagrams in sequence are both valuable forms of communications.
