Strand V
Use Scientific Knowledge from the Earth and Space Sciences in Real-World Contexts

 

Science/Strand V
Content Standard 2
All students will describe the characteristics of water and demonstrate where water is found on Earth; describe how water moves; and analyze the interaction of human activities with the hydrosphere. (Hydrosphere)

Science/Strand V/Content Standard 2/Middle School
Benchmark 1
Use maps of the Earth to locate water in its various forms and describe conditions under which they exist.

Benchmark Clarification

Water exists in various forms on Earth. Different conditions cause water to exist as a liquid, solid, or gas.

Students will:

  • Use a variety of maps such as relief, weather, topographic, road maps, and satellite images to locate water on Earth
  • Use a variety of maps to interpret the state of water at a specific location on Earth

Instructional Example

Benchmark Question: Where is water found on Earth and what are its characteristics?

Focus Question: What is the relationship between latitude and elevation on the forms that water takes on the EarthÕs surface?

Students will use a variety of maps to locate where various forms of water occur on the EarthÕs surface (i.e., in solid and liquid states, water vapor is always present in the atmosphere). Students will make a data table listing the examples and the state of matter associated with each example. Students will discuss where each form of water exists. Students will graphically show relationships between the form that water takes and its location based on latitude and elevation. Students should conclude that water in its solid state is found at higher elevations and higher latitudes. Water in its liquid state is found at lower elevations and lower latitudes nearer the equator.

Note: Half of MichiganÕs residents get their water through groundwater. Ground water should be included in instruction of this benchmark.

Assessment Example

Students will form small groups. Each group will choose a continent and obtain maps and references for one of the continentsÕ regions. (Consider surface maps, relief maps, an almanac, and internet sites that are listed in the resources). It may be hard to find these maps for regions outside the U.S. Each group will research to find the elevation of the snow line for each mountain chain, the direction of flow for major rivers, and the location of major bodies of water (if applicable). Each group will develop a chart listing the two forms of water and ten different surface features according to the form of water found on that feature. Each student will write an essay that explains the role that latitude and elevation play in the form that water takes across this region of the continent.

Note: The teacher will need to provide substantial background information for students, it will be difficult to list a surface features on which ice will occur beyond mountain tops and valleys.

(Give students rubric before activity.)
