We have learned about the surface layer of the ocean: the epipelagic zone. As we continue our study of the ocean divisions, we will now investigate the deep ocean, where light is not abundant. This area can be divided into two major regions: The mesopelagic zone (200 meters to 1000 meters)and the deep ocean (1000 meters to 6000 meters and beyond).
MODULE 14 The Deep Ocean Study Notes (pages 333 – 342)
Because there is so little light in these regions, organisms are specially equipped in their body design to live in this region and to find food.
As a class we performed Experiment 14.1 Chemical “Bioluminescence”. In this experiment we observed that chemical reactions occur more slowly at lower temperatures and more rapidly at warmer temperatures. Therefore the colder water in the mesopelagic enables organisms to produce the light-producing chemical reactions slowly over a longer period of time. Make sure that this lab is completed in your lab book.
Homework due March 15, 2011:
- Take Module 13 Test
- Read Module 14 pages 333 – 351
- Answer On Your Own questions 14.1 – 14.11
- Answer Study Guide questions 1 – 28
- Complete Experiment 14.1 in Lab book
- Notebook check
We will finish up Module 14 in class on March 15. After that class I will assign Module 14 Test.
Thank you to Annalee (aka Superwoman) and Isaac (Venice Ironman) for participating in our Superhero class challenge! Isaac was voted on as winner for his “Venice Iornman.” March 15th class challenge is to dress in the most colorful clothing. Happy Spring!
Have a wonderful Spring Break. Mrs. S
