  5. Recent Events in Science Russia Meteor Blast Is Biggest in 100 Years Read All About It! The dramatic fireball that exploded over Russia on Friday, Feb. 15 was apparently the biggest such blast in more than a century, scientists say. The object that caused the Russian fireball, which damaged hundreds of buildings and wounded perhaps 1,000 people in the Chelyabinsk region, was originally probably about 50 feet (15 meters) in diameter and weighed roughly 7,000 tons, said Peter Brown, director of the Center for Planetary Science and Exploration at the University of Western Ontario in Canada. From multiple sensors using multiple technologies, a best initial estimate of the total energy of the event is about 300 kilotons of TNT-equivalent, Brown said, though he stressed that the number could change as scientists learn more. www.space.com/19822-russian-fireball-biggest-explosion-century.html www.youtube.com/watch?v=ANm_4k7OLDk www.youtube.com/watch?v=dBvotWfR3j4

  6. Ocean Life The marine environment is inhabited by a wide variety of organisms. Most of these organisms live within the sunlit surface waters. Many are photosynthetic.

  7. Ocean Life Classification of marine organisms Plankton (floaters) include all marine organisms – algae (phytoplankton), animals (zooplankton), and bacteria – that drift with ocean currents. Most of Earth’s biomass consists of plankton adrift in the ocean.

  8. Phytoplankton - Algae

  9. Zooplankton - Animals

  10. Photosynthetic Bacteria

  11. Ocean Life Classification of marine organisms Nekton (swimmers) include all animals capable of moving independently of the ocean currents, by swimming or other means of propulsion.

  12. Nekton – Great Reef Shark

  13. Nekton - Squid

  14. Nekton – Blue Tang

  15. Nekton – Moray Eel

  16. Ocean Life Classification of marine organisms Benthos (bottom dwellers) describe organisms living on or in the ocean bottom. A great number of species exist on the shallow coastal floor, but most live in perpetual darkness in deep water.

  17. Benthos – Sea Star

  18. Benthos – Yellow Tube Sponge
