2. Date: 09/06
Topic: Aquatic Ecosystems
Learning Target: Investigate the chemical factors in aquatic systems.

3. Bell Ringer: write silently in your notebook!
Pick up a manila folder from my desk write your name on it
Describe what you see in the following 3 pictures above.
What do you think caused the coral reef to die in less than 1 year?
Do you think it can be reversed and be healthy again? If so, how?

4. Today…
We will explain that different types of organisms exist within aquatic systems due to chemistry, geography, light, depth, salinity, and/or temperature.
We will investigate the chemical factors in aquatic systems.

5. VOCABULARY!!!

7. Ocean Diagram

8. Notebook Output
Silently write on the LEFT SIDE of your notebook, page 2
Raise your hand to ask and answer questions
Write what is in ORANGE

9. Temperature What will happen when we change the temperature?
Temperature needs to be moderate for aquatic life
Temperatures that are too hot or too cold will cause aquatic organisms to die

10. Disturbances What happens when we increase the storm severity
Severe disturbances in an ecosystem cause organisms to die

11. pH
What do you think would happen if the pH was changed to make the ocean very acidic or very basic?
What is an example of an acid?
The pH of an aquatic system must be close to neutral (7) for organisms to survive

12. Salinity Concentration of dissolved salt in water.
What do you think would happen if the amount of salt in the ocean was suddenly changed?

13. Nutrients and Pollutants
What would happen if sewage was dumped into the ocean?
Pollutants in aquatic systems cause organisms to die
The nutrients and dissolved gases in an aquatic system must remain constant (ex. Nitrogen and Phosphorus)

14. Gases Oxygen: The air we breath
Carbon Dioxide: odorless gas produced by burning carbon and organic compounds and by respiration.

15. Gizmo time!!!!!!
We will work together as a class to answer the following questions….
You must stay on task at all times!!!!!
One at a time a student will come up the the board and set the expectations
