  1. Science Education at SeaSEAS Elementary Teacher Workshop The Florida Aquarium January 23, 2010 Heather Judkins, PhD, Teacher Programs Coordinator

  2. Introductions • Fish School • Find your school. • Introduce yourself. • Why are you attending this workshop? • What do you hope to get out of it? • Build a consensus and share with the class.

  3. The Florida Water Story Key Concepts: We are inextricably connected to aquatic systems. Learning to protect our aquatic systems protects all life in the long run.

  4. Water on the Earth Water is continuously circulated- the water or hydrologic cycle www.forks.wednet.edu

  5. The REAL Water Cycle • Water moves from through different places and phases (liquid, solid, gas). • The sun drives the cycle. • Heat energy increases, motion of water molecules increases- from solid (ice), to liquid, to gas (water vapor). • Heat energy decreases, the opposite occurs. • These changes allow water to move through air, land and bodies of water.

  7. Play Globe Toss!

  8. Water on Earth Facts • 71% water • 3% frozen freshwater- ice caps, glaciers • <1% readily available- not polluted or frozen

  9. Recycled Water Classroom activity

  10. Water Cycle Power! • Evaporation from oceans controls the weather and climate patterns of the entire planet! How? • Precipitation ranges from 0.1 inches in the desert to over 900 inches per year in the tropics. • Florida averages 53 inches per year. • In the U.S., humans use about 400 billion gallons of water per day (USGS).

  11. Florida’s Growth Florida receives about 700 new residents per week! How does this impact the water cycle?

  12. Emphasize that water travels through many paths, animals, places and states of matter. All living things depend on water for survival, but only a small amount is available to use. Humans can positively and negatively impact the water cycle. Responsible use of our water resources is good for every living thing. Water is fun and it’s everywhere! Water Cycle Summary

  13. What did one raindrop say to the other raindrop? My plop is bigger than your plop! What happens when it rains cats and dogs? You have to be careful not to step in a poodle. What do you call it when it rains chickens and ducks? Fowl (foul) weather.

  14. Raise Your Hand if You Live in a Watershed…

  15. Make Your Own Watershed Demonstration

  16. More than 100 tributaries flow into Tampa Bay, including dozens of meandering, brackish-water creeks and four major rivers -- the Hillsborough, Alafia, Manatee and Little Manatee. • More than 4 billion gallons of oil, fertilizer components and other hazardous materials pass through Tampa Bay each year. • Currently, more than half the nitrogen entering Tampa Bay comes from stormwater runoff from urban and residential areas. Stormwater is the water that runs off the land with rainfall, carrying with it fertilizer and pesticide residues, as well as trash.

  17. Rainfall and groundwater enter surface waters Wildlife habitat Storage and protection of fresh water Wetlands - Retain water - Improve water quality - Avoid flooding Raise your hand if you live in a watershed. Watersheds and Surface Water

  18. Groundwater St. Johns River Water Management District

  19. Floridan Aquifer is a confined aquifer Groundwater (below) and Surface Water (above) connected Springs, Recharge Areas Sinkholes Features collectively known as Karst Karstic Landscapes- on the surface The Groundwater Connection Florida has more springs and available groundwater than any other state in the country!

  20. Recharging the Aquifer • Rainfall replenishes groundwater • What materials below are most likely to allow for recharge? Least likely? Why? Soil Sand Clay Concrete Gravel Limestone Mulch Tar Carbon

  21. What are Wetlands?

  22. There are a variety of definitions! For simplicity… Transition areas between aquatic and terrestrial systems: • Saturated by water or covered by water at some time each year (e.g., flooding) 2) Hydric Soil 3) Specialized plants adapted to wetland conditions

  23. Marsh

  24. Swamp

  25. Bog

  26. Mangrove Swamps

  27. Wetland Metaphors

  28. What you might encounter in a wetlands habitat…

  29. Plants: Pitcher plant Pickerelweed Cattails

  30. Mangroves Cypress Trees

  31. Mammals Raccoon North American River Otter West Indian Manatee

  32. Reptiles Diamondback Terrapin Black Mangrove Snake Box Turtle Florida Banded Water snake Red bellied Turtles

  33. American Alligator

  34. Birds Frigate Bird Great Blue Heron Woodstork Osprey Cormorant

  35. Reddish Egret Night Heron Spoonbill Ibis Tricolored Heron

  36. Invertebrates Lobster Clam Blue Crab Horseshoe Crab Ghost Shrimp

  37. Fish Snook Pipefish Mangrove Snapper Southern Stingray

  38. Challenges for Wetlands Animals and Plants

  39. Tampa Bay Wetland Losses…

  42. Become a Wetlands Expert Explore the Wetlands Gallery

  43. Estuaries Coastal areas Fresh and salt water meet and mix Brackish Lower salinity than ocean

  44. Varies with rainfall, tides, freshwater inflow, seasons With strong river current inflow, a layer of freshwater can form on top of saltwater. How is this possible? Creates unique environment- both fresh and saltwater fish Well-mixed estuaries- salinity increases away from river’s mouth Remarkable biodiversity- organisms adapted to changing salinity Salinity

  45. Why are estuaries so productive? • River water carries nutrients • Wetlands filter out pollutants and stabilize soils • Shallow estuaries allow for phytoplankton, sea grass and algae growth • Mangroves create a sheltered, nutrient rich environment for young organisms

  46. Nurseries of the Sea • Breeding and Nursing Areas • About 75% of commercially and recreationally harvested marine species • Economic impact of estuary degradation

  47. Florida’s Estuaries • Vary in size and shape • Mangrove Communities • Gulf of Mexico- most end in a bay system • Atlantic Coast- most long and narrow bordered by barrier islands • All Florida residents live near an estuary!
