  1. Ocean Water Chemistry Essential Question: What physical characteristics make up an ocean environment and how do they vary? http://www.youtube.com/watch?v=tzBJy6BXf5Y

  2. Activites: • Salt water vs. Fresh water • Freezing time: • Density: • Observations:

  3. Notes:

  4. Notes:

  5. Concentration Activity: • What difference did you notice between the 2 samples? • What caused the difference? • How does this explain concentration?

  6. Notes:

  7. Notes:

  8. Notes:

  9. The WaterColumn: Pressure increases Temperature decreases

  10. Notes:

  11. Pressure Activity – techbook: • Materials: • • Bottled water – 1 L • • Duct tape • • Large push pin • • Meter stick • • Permanent marker • • Paper towels • • A table • • Roll of butcher paper • • Writing paper or science notebook for recording ideas

  12. Pressure Activity – techbook: Draw a sketch of the bottle from the side. From which hole did the water spray the farthest? Why? From which hole did the water spray the shortest? Did you see a pattern? How does this experiment relate to the water pressure at various depths of the ocean?
