Water Is Water Focus Question How are the animals that live in the ocean different than the animals that live in a swamp? Why are the kinds of animals so different if they both live in water? Activity Synopsis Students observe the Great Ocean Tank and Blackwater Swamp exhibits in the S.C. Aquarium. Students group organisms according to habitat and determine why the habitats are so different. Time Frame 1 hour Student Key Terms swamp ocean fresh water salt water salinity adaptation physiological Objectives The learner will be able to: Group animals according to habitat and observe the differences between the two habitats. Second Grade Standards Addressed Science Standards IA1a, IA4a, IB1a, IB1c, IIA2a, IIA2b Background Key Points Key Points will give you the main information you should know to teach the activity. Blackwater swamps are a type of freshwater wetland. The salty ocean water covers nearly 70% of the Earth’s surface. With a few exceptions (such as salon and striped bass), salt water organisms cannot live in fresh water habitats and vice versa. Organisms in each habitat have adapted physiological responses to their particular surroundings. Detailed Information Detailed Information gives more in-depth background to increase your own knowledge, in case you want to expand upon the activity or you are asked detailed questions by students. (Information from /owow/wetlands/types/swamp.html) A swamp is defined as a wetland that is dominated by woody plants. This is in comparison to a salt marsh, for example, that is dominated by the perennial grass, Spartina. The types of swamps vary. For example, in the Northeast, red maple swamps are most common, whereas in the Southeast, we have the familiar bottomland hardwood forests. These swamps are located along the slow-moving rivers of the Coastal Plain. Two important characteristics of swamps are (1) saturated soils during the growing season, and (2) standing water during certain times of year. The soils in swa
