  1. 1. Fishing in the ocean Physics for Kids http://mocomi.com/learn/science/physics F UN FOR ME! Copyright © 2012 Mocomi & Anibrain Digital Technologies Pvt. Ltd. All Rights Reserved.
  2. 2. Fishing in the ocean Fishermen use a device called the fish-finder which sends out sound waves. These sound waves bounce off schools of fish and reflect back to the fish-finder. A display panel on the fish-finder tells the fishermen where there fish are. F UN FOR ME! Copyright © 2012 Mocomi & Anibrain Digital Technologies Pvt. Ltd. All Rights Reserved.
  3. 3. Fishing in the ocean Fishermen also have the option of using satellites to get information on fish. Fish live in areas where a certain temperature suits them the most. Fishermen know about about this and and use satellites which can read ocean temperatures to locate schools of fish. F UN FOR ME! Copyright © 2012 Mocomi & Anibrain Digital Technologies Pvt. Ltd.

  4. 4. Fishing in the ocean SATELLITES READ SURFACE TEMPERATURES Satellites help detecting surface temperatures only. So this only allows fishermen to find fish that swim near the surface of the oceans. F UN FOR ME! Copyright © 2012 Mocomi & Anibrain Digital Technologies Pvt. Ltd. All Rights Reserved.
  5. 5. Fishing in the ocean ADDITIONAL INFORMATION A fish-finder operates almost like a radar, except that a radar uses radio waves and a fish-finder uses high-frequency sound waves. There are two types of fish-finders, the simpler one transmits sound waves downwards while the more complex one transmits waves in all directions, therefore covering a larger area, providing more data.

  6. 6. Fishing in the ocean PROJECT Classify these fish (sharks, whales, crabs, prawns, tuna, salmon, king fish, squid) into shallow water or deep sea fish. What is the difference between a fresh water fish and a salt water fish? Try your hand at fishing at a nearby pond, lake or even the sea. Ensure you are accompanied by an elder for this project. All you need for the activity is a good sturdy stick, some rope, a hook and some dough. Assemble your fishing rod, and go fishing!
