This activity allows you to bring science, math, and writing all together. The students are to take on the role of both the atom and water but may choose from the formats provided. The students have to think about what state of matter each changes to when the temperature changes. Math comes in because the students can tell the teacher the temperature at which something boils or freezes. Students are also having to identify the cause and effect relationship or chronological order in which it happens. For the atom, students have to complete a friendly letter or newspaper article.
