1. The Singing Salmon Shanon C. Trevor M. Trevor M. Kristen J. Kristen J. Kyrie K. Kyrie K. Jerot S. Jerot S.

2. Where do we come from? We attend La Center High School. Which is located North of Vancouver.

3. What Do We Do? Test water with two fourth grade classes Take record of each day tested Raise 1000-2000 ChoHo and Chum eggs Release our salmon into our watershed

5. Hypothesis If the dissolved oxygen (ppm) and turbidity (cm) are high then there is a higher probability of salmon survival because the water would be breathable and there is less sediment.

6. What is Dissolved Oxygen? The saturation of oxygen in water. Why is Dissolved Oxygen Important? D.O is what allows the Fish to breath and makes it easier for decomposition of matter in the water.

8. What is Turbidity? Turbidity indicates the amount of suspended sediment in the water. Why is Turbidity Important? High turbidity can have negative effects to aquatic life, such as suffocation due to the high amounts of sediment in the water.

Turbidity can also be measured in NTU’S (Nephelometric Turbidity Unit)
