Properties of matter come in two main groups: chemical and physical. Reactions between different substances, often involving heat, count as chemical properties of matter. Think of making a cake: Mixing ingredients together and putting them in the oven creates a new substance. Physical properties of matter involve what a particular substance does in its solid, liquid and gaseous states. While many liquids exhibit only one commonly seen state, others, such as water, exhibit all three in nature: ice, water and steam.

## 1Water's Properties of Matter

Ask students to discuss any substances in nature they can think of that exhibit all three physical properties of matter -- solids, liquids and gases.

Prompt students to think about water if no one has come to this conclusion.

## 4Write on the board

Write on the board the physical transitions water goes through. Give temperatures in both Fahrenheit and Celcius for water’s transitions from ice to water (at 32 degrees and 0 degrees, respectively) and water to steam (at 212 degrees and 100 degrees, respectively). Remind them of terms that signify changes in properties of matter, such as freezing, melting, condensing and evaporating.

## 6Pass out ice cubes and paper cups and to each student or each group

Pass out ice cubes and paper cups to each student or each group. Have students write down observations about their ice cube.
