 the Netherlands you will notice that the channel narrows and its name changes to the Strait of Dover. Explain that a strait is a narrow channel.
Tell the students that the last water feature they are going to learn about is a reservoir. Explain that a reservoir is a place used to collect and store water. It looks something like a pond or a lake, but is special because its purpose is to store water. Some reservoirs store drinking water for communities. These reservoirs are protected so that we have a supply of clean drinking water. Ask: Why do you think we need to store water? (ready supply of water for drinking, household needs, watering gardens and crops) What would happen if there was a drought, not enough rainfall, and we didn't have a ready supply of water?
Review each of the new geographical water features with the class by stating the definition and calling on students to name the appropriate water feature.
