Acadia National Park - Turbidity Instructional Video

The video tutorial explains turbidity, a measure of water cloudiness, and how to measure it using a Secchi disk and a turbidity chart. It introduces Jackson Turbidity Units (JTU) and provides a step-by-step guide for conducting a turbidity experiment using a nature study kit. The tutorial also discusses factors that cause turbidity, such as suspended particles and organisms, and suggests ways to test turbidity at home using common household items.

What is the primary purpose of a turbidity jar in the nature study kit?

• To determine the cloudiness of water

• To measure the temperature of water

• To store water samples

• To filter impurities from water

Which tool is used to measure the cloudiness of water?

• A hydrometer

• A thermometer

• A Secchi disk

• A pH meter

What does JTU stand for in turbidity measurement?

• Junction Turbidity Unit

• Joule Turbidity Unit

• Jupiter Turbidity Unit

• Jackson Turbidity Unit

What should you ensure before starting the turbidity experiment?

• The timer is set to 10 minutes

• The jar is empty

• The surface is flat and stable

• The water is cold

What is the first step in the turbidity experiment using a tea bag?

• Add salt to the water

• Fill the jar to the fill line

• Shake the jar vigorously

• Boil the water

Which of the following can cause high turbidity in water?

• Clear skies

• Low temperatures

• High pH levels

• Microscopic organisms

What can you use at home to test for turbidity?

• A compass
