Earth’s most magnificent and enormous landforms are all on the ocean floor. Volcanoes and earthquakes change the ocean floor, creating new landforms. Erosion on land also deposits minerals and animal matter on the ocean floor.
The classroom resource provides a slide show that will describe the landforms on the ocean floor and how they are created through geologic processes. There is also a short test that can be used to assess students' understanding.
This guide was developed to support teachers in teaching topics with real-world context and provide them with the background to feel competent and comfortable when teaching about the ocean. It provides a solid introduction to the ocean and the ocean literacy principles in an accessible and reader-friendly manner. In addition to general information about the ocean, the guide includes numerous education features, such as teaching tips and student thinking, that help to connect the content to classroom practice.
The purpose of this lesson is for students to explore how an indefatigable scientist used her knowledge of math and map making to create a map of the ocean floor, confirming the theory of continental drift (plate tectonics). This lesson uses a book called Solving the Puzzle Under the Sea, written by Robert Burleigh with illustrations by Raúl Colón. In this illustrated biography, Burleigh tells the story of Marie Tharpe’s imagination and perseverance and shares the story of this pioneering female scientist, who was the first person to ever successfully map the ocean floor. Her map helped confirm the theory of plate tectonics to the scientific community.
