Testing Water Turbidity Using a Sensor

The video tutorial explains the concept of water turbidity, its causes, and its significance, particularly in relation to the Chesapeake Bay's ecosystem. It demonstrates how to measure turbidity using a sensor, comparing samples from the Bay and a pond. The tutorial highlights the importance of maintaining balanced turbidity levels for the health of aquatic life, such as oysters, which rely on filtering water for nutrients.

What can high turbidity in water indicate?

• Presence of fish

• Pollution or algal blooms

• Low pH levels

• High oxygen levels

Why is it important to clean the equipment before testing water turbidity?

• To make the equipment last longer

• To ensure the equipment is visible

• To avoid smudges that can affect readings

• To prevent water from evaporating

What role do oysters play in the Chesapeake Bay concerning water turbidity?

• They filter out particles, reducing turbidity

• They increase turbidity by stirring up sediment

• They have no effect on turbidity

• They add nutrients to the water

Why does pond water generally have higher turbidity than bay water?

• Pond water is deeper

• Pond water has more concentrated particles

• Bay water is warmer

• Bay water is saltier

What is the standard unit for measuring turbidity?

• PSI

• LUX

• PPM

• NTU
