• TLF-IDA003809

In this lesson sequence, students explore what water is and how it behaves as it changes from ice to liquid water to water vapour. The purpose of this lesson sequence is to give students a mental picture of water molecules. Learning about how these molecules behave when water is heated and cooled can help them to understand ...
