Concept map Work in your group to create a concept map about water.
Concept map
Read the introduction and look for key ideas Like clouds, fog is also made up of tiny drops of water. If you have ever been in fog, you know what the inside of a cloud is like!

Analysis question 1 Copy the three lists of words below. List 1 List 2 vapor water evaporation liquid solid condensation melting
Analysis question 1 a. Look for a relationship among the words in each list. Cross out the word in each list that does not belong. List 1 List 2 List 3 vapor water evaporation liquid solid condensation melting
Analysis question 1 b. Circle the word in each list that includes the others. List 1 List 2 List 3 vapor water evaporation liquid solid condensation melting
Analysis question 1 c. Explain how the word you circled relates to the other words in the list. List 1 List 2 List 3 vapor water evaporation liquid solid condensation melting
Analysis question 2 The amount of water on the earth today is the same as it was 100 years ago. Use your knowledge from this activity to explain how this could be true.
How does water change?
Key vocabulary definitions Cloud - A visible collection of water droplets in the atmosphere. Clouds usually form hundreds of meters above Earth’s surface but fog is a cloud formed near Earth’s surface. Condensation - The process of change in state from gas to liquid, or the droplets of liquid formed from this process.
Key vocabulary definitions Evaporation - The process of change in state from a liquid to a gas. Freezing - To change from a liquid to a solid state. Humidity - The amount of water vapor in the air.
Key vocabulary definitions Melting - To change from a solid to liquid state.
Key vocabulary definitions Water cycle - The movement of water from one state to another as it circulates through the earth’s crust, oceans, and atmosphere. Water evaporates from the surface, rises and cools at higher elevations, condenses as rain or snow, and falls to the surface where it collects in lakes, oceans, soil, and rocks underground.
Key vocabulary definitions Water vapor - Water in a gaseous state.
