Science, Grade 9 - 12, Marine Biology Elective, 2005

1.) Select appropriate equipment for scientific field investigations in marine environments.

•  Identifying patterns and relationships determined from collected data
•  Solving for unknown quantities by manipulating variables
2.) Differentiate among freshwater, brackish water, and saltwater.

3.) Describe physical characteristics of oceans, including topography of the ocean floor, plate tectonics, wave motion, depth, and pressure.

4.) Recognize interactions between the atmosphere and the ocean.

•  Describing how waves, ocean currents, and tides are generated
5.) Discuss physical and chemical properties of saltwater.

Examples:

- physical—turbidity, temperature, density;

- chemical—salinity, pH, dissolved gases

6.) Describe components of major marine ecosystems, including estuaries, coral reefs, benthic communities, and open-ocean communities.

7.) Identify patterns and interrelationships among producers, consumers, scavengers, and decomposers in a marine ecosystem.

8.) Describe characteristics of marine plant and algae divisions.

•  Describing commercial, economical, and medicinal values of marine plants and algae
9.) Arrange various forms of marine life from most simple to most complex.

•  Classifying marine organisms using binomial nomenclature
•  Identifying characteristics of ocean-drifting organisms
Examples: phytoplankton, zooplankton

•  Identifying characteristics of marine invertebrates
Examples: Protozoa, Porifera, Coelenterata, Arthropoda

•  Identifying characteristics of marine vertebrates
Examples: fishes, reptiles, birds, mammals

•  Identifying characteristics of marine plants
Examples: algae, seaweed

•  Describing adaptations in the marine environment
10.) Describe the anatomy and physiology of representative aquatic organisms.

•  Identifying different aquatic species using dichotomous keys
11.) Describe positive and negative effects of human influence on marine environments.

Examples:

- positive—reef restoration, protection of endangered species;

- negative—pollution, overfishing

12.) Identify various careers related to marine science.
