The teacher lets each group to decide 2 members as letter ‘O’ and one member as ‘H’. These three members are stack to each other and they can move together. The students continue to move in the classroom with 2O and 1H. The teacher explains that when the music stops, there will be three words that each group will act in the classroom based on this word.

–       Solid: All groups come together and dance or walk.

–       Liquid: Each group can dance or walk as they wish but the groups are not attaching to each other.

–       Gas: Each group dances or walks separately from other groups and they try to be far from each other.

Then the teacher divides the class into four groups. Each group improvises the change of water forms. They start from one form and finish the improvisation with another.

Group 1. From Solid to Liquid

Group 2. From Liquid to Solid

Group 3. From Liquid to gas

Group 4. From Gas to Liquid

Tips to the teacher: The improvisation can be short but it can be good to have a story in it. Therefore it can be good to let students to discuss how they change the form.

 

Phase 5

The teacher asks to the students about examples for these three forms

–       Liquid: juice, soep etc.

–       Solid: Spoon, stone etc.
