Subject: MarcoGram: By the Sea

The MarcoGram: For educators, principals and teacher-trainers.

By the Sea

April is National Zoo and Aquarium Month and MarcoPolo has collected lessons that use marine biology and maritime history to illustrate basic concepts in economics, math, art, geography and much more. Use the warm-up activities below to get your students interested in animals, aquatics and maritime adventures, then scroll down to find links to more lessons to help celebrate National Zoo and Aquarium Month in your classroom.

Warm-up Activities:
 
Pirate Map 1. Blackbeard the Pirate is one of the most well known pirates in history. Where did he live? (Answer: Born in Jamaica, Blackbeard owned a house in North Carolina.) Can you name any other pirates? Where do you think they lived? Where did they sail? On a world map, mark and color in the areas where some famous pirates traveled.

Explore a "Pirate Map" (Grades 3-5), Xpeditions, National Geographic Society.

2. American consumers spend more than $46 billion each year on a wide variety of fish and shellfish products, and, worldwide, fish is the most consumed animal protein. Fisheries and aquaculture farms contribute to the fish population which, in turn, helps alleviate hunger in underdeveloped nations. Are there any drawbacks to "fish farming?" Create an argument for or against commercial fisheries. Support your findings with social, economic and mathematical statistics. 
Participate in "The Fish Trade" (Grades 9-12), Science NetLinks, American Association for the Advancement of Science.

 
Ocean Floor 3. Have you ever visited the ocean? Do you know what types of animals live in the ocean? Draw a picture of plants, animals and other objects you might find underwater.

4. You can estimate the weight of a whale by measuring its length. Let's assume that a 40-foot whale weighs about 40,000 tons. Based on that, how much does a whale weigh if it's 72 feet long? (Answer: 72,000 tons.) How long is the whale if it weighs 48,500 tons? (Answer: 48 1/2 feet.) Quiz your friends to see if they can figure out the math.

Work on basic math skills in "Application: Using Math in Everyday Life" (Grades 1-8), Illuminations, National Council of Teachers of Mathematics.
 

5. Brine shrimp, also known as "sea monkeys," require special conditions to hatch and live, including water salinity, temperature and water quality. What do you think are the optimal conditions for brine shrimp to hatch? Devise a hypothesis, then create a graphic organizer with the different variables you will use to test your theory.
