Lesson 16:
FRESH WATER AND SALT WATER
This lesson will help students demonstrate basic concepts and principles of physical, chemical, biological, and earth sciences. Apply conditions of nature and science, set up laboratory experiments, demonstrate the effects of salt water and fresh water on marine life, demonstrate the effects of salt water and fresh water on wooden ships, understand the sanitation problems inherent in the maritime experience, and understand the importance of food and drinking water storage on ships in the past and present. Examine and analyze the effects of salt water and fresh water on marine life, wooden ships, and maritime life. Examine the sanitation problems inherent in the maritime experience, such as waste disposal. Food storage and fresh water storage was and still is very important. Study and compare conditions aboard the U.S. Brig Niagara with that of ocean going warships, as well as the situation today.
ACTIVITIES: 1. Set up labs and introduce science experiments dealing with the effects of salt water and fresh water. 2. Read logs and other information available about sanitation procedures on warships and other sailing vessels in the Revolutionary Era to the early 1900s, as well as storage of food and water. 3. Read information on sanitation procedures on lake and ocean-going vessels of today. 4. Interview crew of the U.S. Brig Niagara to determine what is being done aboard the ship today regarding sanitation and food and water storage. 5. In collaboration with other classmates, prepare a comparison relating to sanitation and water storage of sailing vessels in the 1800s with present-day sailing vessels.
