Lesson: Landforms and Oceans
Grade Level:
Five
Content Area:
Earth Science
Core Area:
Changes in Landforms and Oceans
Lesson Overview:
Teachers will participate in a deep-sea mapping expedition as they use
depth probes to make inferences about the landforms in a large, 3D
Ocean Landforms Puzzle. They will compare continental landforms with
oceanic landforms using a variety of models. Images, videos and models
will be used to spark discussion of the ways that natural processes impact
both oceanic and continental landforms.
2005 Standards Correlation: Grade 5
Landforms and Oceans
Standard 5-3: The student will demonstrate an understanding of features, processes, and changes
in Earth’s land and oceans. (Earth Science)
Indicators:
5-3.1 Explain how natural processes (including weathering, erosion, deposition, landslides,
volcanic eruptions, earthquakes, and floods) affect Earth’s oceans and land in constructive and
destructive ways.
5-3.2 Illustrate the geologic landforms of the ocean floor (including the continental shelf and
slope, the mid-ocean ridge, rift zone, trench, and the ocean basin).
5-3.3 Compare continental and oceanic landforms.
2014 Standards Correlation: Grade Four
Earth Science: Changes in Landforms and Oceans
Standard 5.E.3: The student will demonstrate an understanding of how natural processes and
human activities affect the features of Earth’s landforms and oceans.
5.E.3A. Conceptual Understanding: Some of the land on Earth is located above water and some
is located below the oceans. The downhill movement of water as it flows to the ocean shapes the
appearance of the land. There are patterns in the location and structure of landforms found on the
continents and those found on the ocean floor.
Performance Indicators: Students who demonstrate this understanding can:
5.E.3A.1 Construct explanations of how different landforms and surface features result from
the location and movement of water on Earth’s surface through watersheds (drainage basins)
and rivers.

5.E.3A.2 Develop and use models to describe and compare the characteristics and locations
of the landforms on continents with those on the ocean floor (including the continental shelf
and slope, the mid-ocean ridge, the rift zone, the trench, and the abyssal plain).
5.E.3B. Conceptual Understanding: Earth’s oceans and landforms can be affected by natural
processes in various ways. Humans cannot eliminate natural hazards caused by these processes but
can take steps to reduce their impacts. Human activities can affect the land and oceans in positive
and negative ways.
Performance Indicators: Students who demonstrate this understanding can:
5.E.3B.1 Analyze and interpret data to describe and predict how natural processes (such as
weathering, erosion, deposition, earthquakes, tsunamis, hurricanes, or storms) affect Earth’s
surface.

Resources for Teachers:
http://oceanexplorer.noaa.gov/edu/ This is the Education section of the National Oceanic and
Atmospheric Administration. Lots of good material here!
Investigate undersea landforms using Google Earth. It has the ability to let you go below sea level
and travel through trenches, over ridges, and along the continental shelf.
http://joidesresolution.org/ The Joides Resolution is a seagoing research vessel that drills core
samples and collects measurements from under the ocean floor, giving scientists a glimpse into
Earth’s development. The site includes a variety of resources for teachers and students.

Procedures
Label oceanic and continental landforms on models
then match oceanic landforms with continental
landforms in pocket chart.
Students each get a landform label to describe and place
on the model or in the pocket chart.
Engage
• All use hands and arms to model landforms as they are
discussed and labeled.
• Use world map to review geography, terms, units, use
of a color-coded scale to find landforms on map.
• Softball= model of Earth, stitching = mid-ocean ridge
Explore
Survey the sea floor in the large ocean model.
Students plan and conduct the investigation.
Provide sounding poles & guidance and monitor time.
Predict where landforms are based on pattern of sticks.
Remove and collect sticks; remove lids to see inside.
Were predictions correct?
Explain
• Constructive and destructive forces in land formation
• Divergent, convergent and transform plate boundaries
• Model scale and exaggeration in the large ocean model
[Horizontal Scale: 1 in. =30 mi., Vertical Scale: 1
in.=2500 ft. or ½ mi., Vertical Exaggeration 60:1]
• Reasons for modeling selected region of ocean
Elaborate
• What region of the world does the model represent?
• Show slides with map of region and images of area.
• Discuss continental landforms in the model, how they
formed, and evidence in the model that connects
continental landforms to oceanic landforms. • Ask and discuss: Why do we need to know about
landforms in the ocean? Evaluate
• Students create and label their own 3D seafloor model
• Students draw and label a diagram of the seafloor
• Students draw & explain 3 types of plate boundaries
