Earth Science Unit Study - Week 23 - OceansWe measured the depth at different points of a model ocean.
Did you know that cold water corals dominate much of the ocean floor and they sometimes build colonies taller than skyscrapers? During the last century scientists have gained vast insight into the ocean. Major advances in technology such as sonar and submersible vehicles have led to many discoveries. Unknown creatures have been identified, much of the floor has been mapped and soil boring samples have helped to unlock the mysteries of how certain underwater topology was created.
Before sonar technology, oceanographers first mapped the ocean floor in certain locations by lowering a rope into the water. This painstaking method is explained well in the beginning of How The Earth Was Made, The Deepest Point linked below.
Ocean Floor Mapping Activity
The kids were challenged to create a sketch of the floor of a model ocean.
Whenever kids are given the opportunity to think, discover and solve problems on their own, their motivation seems to increase. This project was perfect for motivation. The kids were presented with the box and asked if they wanted to create a sketch of the ocean floor.
They decided how to measure the depth and what tools to use.
