What Is the Water Cycle?
What are the Three States of Water?
When starting a new activity, it is always a good idea to focus the attention your students. Begin this activity by engaging students in a discussion about the states of matter. Ask students, Where can you find water on Earth? Students may give examples such as lakes, rivers, oceans or groundwater. They should understand that water also exists in solid and vapor form. Solid water occurs in nature as snow or ice. In fact, snow or ice can appear in a lot of places that are not mountains, glaciers and icebergs. Water vapor, the gas phase of water, can be found in our atmosphere. Although water is abundant, freshwater is a limited resource. Ask students if they think water changes from one state or form to another.
