Clarification Statement: none

Assessment Boundary: none

Evidence Statement

Learning Objectives

By the end of the lesson, students will be able to:

  1. Identify locations where water is found on Earth.
  2. Recognize that water can exist in both solid (ice) and liquid states.
  3. Understand the patterns of water distribution on Earth.

Vocab and definition

Vocabulary:

  1. Water
  2. Solid
  3. Liquid
  4. Ice
  5. Oceans
  6. Rivers
  7. Lakes
  8. Clouds

Definitions:

  1. Water:Water is a transparent, tasteless, and odorless liquid that is essential for the existence of life on Earth. It can exist in various forms, including liquid (as in oceans, rivers, and lakes) and solid (as ice) or gas (as water vapor).

  2. Solid:Solid refers to the state of matter characterized by a fixed shape and volume. In the context of water, it can exist as ice when the temperature is low enough to cause it to freeze.

  3. Liquid:Liquid is a state of matter characterized by having a definite volume but no fixed shape. Water in its liquid state is common in rivers, lakes, and oceans.

  4. Ice:Ice is the solid form of water that occurs when liquid water freezes, typically at temperatures below 0 degrees Celsius (32 degrees Fahrenheit).

  5. Oceans:Oceans are large bodies of saltwater that cover about 71% of the Earth's surface. They play a crucial role in regulating the planet's climate and supporting diverse ecosystems.

  6. Rivers:Rivers are natural watercourses that flow towards an ocean, sea, lake, or another river. They are important for transporting water, sediment, and nutrients across landscapes.

  7. Lakes:Lakes are large bodies of water that are surrounded by land. They can vary in size and depth and are often fed by rivers or other water sources.

  8. Clouds:Clouds are visible masses of water droplets or ice crystals suspended in the atmosphere. They play a key role in the water cycle and weather patterns.

  9. Water Cycle:The water cycle is the continuous movement of water on, above, and below the Earth's surface. It involves processes such as evaporation, condensation, precipitation, and runoff.

 

Materials

 

 

 

 

 

Materials:

  1. Large world map or globe
  2. Pictures or images showing water in various forms (rivers, lakes, oceans, ice, clouds)
  3. Chart paper or whiteboard
  4. Small containers with water
  5. Ice cubes
  6. Books or resources about water on Earth

Teacher Notes

    Pre-lesson Discussion:

    • Initiate a discussion about where students have seen water and in what forms (e.g., rivers, lakes, rain).
    • Introduce the terms "solid" and "liquid" and ask students for examples of each.

    Lesson Activities:

    1. Introduction to Water on Earth (CCC):

      • Show a large world map or globe to the class.
      • Discuss the major water bodies such as oceans, rivers, and lakes.

    2. Visual Exploration (SEP):

      • Display pictures or images showing different forms of water (rivers, lakes, oceans, ice, clouds).
      • Ask students to identify and categorize each form of water.

    3. Hands-On Exploration (SEP):

      • Distribute small containers with water and ice cubes to each student or group.
      • Observe and discuss the changes in the state of water as it freezes into ice and melts back into liquid.

    4. Class Discussion and Charting (CCC):

      • Lead a class discussion about the different forms and locations of water on Earth.
      • Chart the identified locations on paper or the whiteboard.

    5. Read-Aloud and Discussion (DCI):

      • Read books or use resources that further explain the presence of water on Earth and its various forms.
      • Discuss additional information learned from the readings.

    Additional  Notes:

    • Emphasize that water can exist in various forms and locations, contributing to the Earth's dynamic processes.
    • Relate the lesson to the water cycle, explaining how water transitions between solid and liquid states.

    Conclusion:

    Wrap up the lesson by summarizing the key points about the presence of water on Earth, its different forms, and locations. Emphasize the patterns in water distribution and transitions between solid and liquid states. Encourage students to explore further and observe water in their surroundings.

     

     

    Assessment

    Assessment:

    • Observation and Participation (SEP):

      • Assess students based on their participation in hands-on activities, discussions, and their ability to identify different forms of water.

    • Class Chart (CCC):

      • Evaluate the accuracy and completeness of the class chart identifying where water is found on Earth.
