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.
