Sonar Mapping of the Ocean Floor
Eighth graders participate in an experiment that emulates a sonar signal bouncing off the ocean floor. They determine how the ocean floor is measured by the length of time it takes for the sonar signal to return. They work with a wooden...

Mapping the Ocean Floor: Bathymetry
Bathymetry is not a measure of the depths of bathtubs! Through the three lessons, scholars explore two different types of maps and how they are made. The resource focuses on topographic and bathymetric maps and teaching the techniques...

LIDAR: Mapping with Lasers
We would be lost without maps! How are they made? Introduce junior topographers to LIDAR technology with a fascinating activity. Set up a mock city, then have learners operate a laser measure to determine the shape of the landscape using...

Mini-Ocean Bathymetric Mapping Research Cruise
Middle or high schoolers transform into oceanographers in a week-long simulation. To begin, each group follows directions to create a model of the ocean floor with specified features. Next, the groups prepare to set sail on a research...
Curated OER
The Unseen Ocean Floor
Students build ocean floor structures, then map and model an unfamiliar ocean floor. They are introduced to bathymetry and sea floor features, and discover one of the most widely usd methods for studying the ocean.
Curated OER
Map that Habitat
Students participate in an activity that replicates the creation of sea floor bathymetry by taking a simplified form of soundings in the classroom. They discuss sea floor mapping technologies, sonar, soundings, and remote sensing,...

Seeing the Seafloor Using Sound - Multibeam Sidescan Sonar
Students are told that sound is not just stuff that our ears hear. They are explained that it is a tool for measuring and looking at objects in a new way. Students are introduced to sound waves and sonar imaging. They are explained...
Curated OER
Mapping the Ocean Floor
Students construct and interpret a line graph of ocean floor depth and a bar graph comparing the height/depth of several well-known natural and man-made objects and places. In addition, they calculate the depth of two points using sonar...

Seeing Sound & Sonar
Students make inferences based on different sounds that they hear. In this inferences lesson plan, students will hear sounds of different objects and describe the sounds based on what they hear. They will answer various questions about...
Curated OER
Finding the Way
Students identify and research navigational tools used in deep sea explorations. They are introduced to a compass, the Global Positioning System and sonar technology and then describe their uses in underwater exploration.
Curated OER
Ping!
Seventh graders study side-scan sonar and discover how it can be used to locate objects underwater. They complete a sonar simulation activity in which they create and map mystery landscapes inside shoeboxes.

A Watered-Down Topographic Map
Eighth graders explore the ocean floor. In this topography instructional activity, 8th graders compare topographical maps to bathymetric charts. They will create a topographic map and note landmarks and other land features.
Curated OER
Seeing Sound and Sonar
Students grasp how underwater animals can "see" using sound waves. They practice making inferences, and build a conceptual understanding of sonar radar.
