Water Quality Tests

What were the specific water quality test performed on our creeks

• Pollution, dilution, and erosion

• Dissolved Oxygen, pH, and temperature

• Turbidity, pollution, pH

• Photosynthesis, cellular respiration and limiting factors

What does Dissolved Oxygen mean?

• How much acid is in the water

• How cold the water is

• DO

• How much oxygen is in the water

pH is the measurement of

• how acidic or basic a solution is.

• just the acidity of a solution.

• how acidic or basic the atmosphere is.

• Non of the above.

Temperature of the water impacts

• what kind of organisms can live in rivers, creeks and lakes.

• the amount of dissolved oxygen.

• the amount of minerals dissolved in the water.

• all of the above

What is water quality?

• It describes the condition of the water

• It is the continuous movement of water on, above, and below the surface of the Earth

• It is the property of containing salt

• It is the total amount of suspended solids.

What is salinity?

• The property of containing salt

• The amount of suspended solids

• Describes the condition of the water

• Describes how acidic or basic water is

Where are nitrates and phosphates found?

• Fertilizer

• Manure

• Detergent

• All of the above

Why are too many nutrients (like nitrates and phosphates) bad for our waters?

• Nutrients decrease the pH of the water, causing it to become increasingly acidic

• Nutrients change the salinity of the water

• Wetlands filter out runoff that may contain nutrients

• Nutrients in the water cause too much algae growth, which decrease the level of oxygen in the water

_________ is the amount of oxygen dissolved in water.

• dissolved carbon dioxide

• dissolved oxygen

• turbidity

• pH

Why did we need safety glasses?

• To look cool

• To protect our eyes

• Because we see better with them

• Because fish stink
