Aquatic Ecosystems

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

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?

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. https: //www. youtube. com/watch? v=e. Kz 8 r. WTs 28 c

VOCABULARY!!!

Ocean Diagram

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

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

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

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

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

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)

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

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 board and set the expectations
