1. Properties of Water

2. Water Filters UV Radiation
Protects aquatic ecosystems

3. Heat Capacity
Heat Capacity – the amount of heat energy required to increase temperature
Water has a high heat capacity
Slow to heat, slow to cool
Temperature changes slowly

5. Evaporation/Condensation
A lot of energy is needed to evaporate water
A lot of energy is released when water condenses

6. Water dissolves many compounds

7. Water expands when it freezes WHY IS THIS IMPORTANT?

8. Density of Water/Stratification
Cold = more dense
Salty = more dense
Density stratification of water separates the top layer of water from the bottom
- essentially separates the nutrient rich lower layer from the gas rich upper layer
How does water become density stratified?
DESIGN A MODEL TO EXPLAIN HOW DENSITY STRATIFICATION OCCURS (BOTH FRESH & SALINE) – DAY 1

9. Overcoming Stratification
How do lakes become unstratified?
DESIGN A MODEL TO EXPLAIN HOW DENSITY STRATIFICATION IS REVERSED IN FRESH WATER – DAY 2
DESIGN A MODEL TO EXPLAIN HOW DENSITY STRATIFICATION IS REMEDIED IN OCEANS – DAY 3
