Marine Career Discussion
In this chapter students learn about being a maritime archeologist as well as the study of people and their interactions with the sea. Shipwrecks and other archaeological sites attract peoples’ interest. Preserving these sites and artifacts, either underwater or in museums, allows people to experience them and to gain a better understanding of history. John D. Broadwater, PhD, has participated in many challenging and rewarding underwater excavations. Dr. Broadwater’s work allows him to touch history and to learn the stories that only shipwrecks can tell. A solid understanding of all branches of science and math helps him put all the pieces of history he finds together.
As students study this chapter, have them take note of the skills needed to be a maritime archaeologist like Dr. Broadwater. Have them think about how uncovering stories of the past influence what society does in the present and the future. When and how did the study of marine science begin? How has conquest, trade, exploration, science, and technology played a role in the past to developing the study of oceanography as known today?
Mind Capture Demonstration
This teacher demonstration may be used to introduce this chapter or different parts of the chapter, or may be used as a team inquiry-based activity.
History of Ocean Exploration and Marine Sciences – Introduce students to snorkeling and the sport of scuba diving.
a. Have a local scuba diving facility staff member present the wonders of snorkeling and scuba diving to your students. Make sure facility staff members bring snorkeling and diving equipment to show students. Most scuba diving facilities will also have historical pieces of dive equipment on hand.
b. If a scuba diver yourself, explain and show students the equipment necessary to snorkel and dive safely.
c. Ask if any of the students are snorkelers or divers; allow students to present to the class individually or in groups.
EXPECTATIONS / STUDENT CONDUCT
Students may be involved in guided discussion as the teacher explains the content of the chapter through a teacher-led presentation. Students will be expected to respond to questions, ask questions, takes notes, draw and label diagrams.
Students may study the chapter individually as they read and respond to questions.
Students may work in collaborative teams as they conduct inquiry-based activities and work on specific enrichment experiences and assessments.
Students should start each chapter by familiarizing themselves with the chapter vocabulary and morphemes list. Students may develop a chapter concept map using the vocabulary list. This initial concept map can be compared with a summative concept map to determine what learning has taken place and whether misconceptions remain.

Instructional Strategy – Teacher Led Presentation Exploration Through Discussion
HISTORY OF OCEAN EXPLORATION AND MARINE SCIENCES
I. The History of Oceanography-Why Study It?
Reference the National Science Teachers Association (NSTA) SciLinks Service
Topic: History of Oceanography
Go To: www.scilinks.org
Code: LOP2020
By the end of this section, students will be able to answer these questions:
1. What are three reasons to learn the history of oceanography?
2. What are the four main stages in the history of oceanography?
1. The history of oceanography is connected to the general history of the world. Our knowledge and use of the ocean influences, and is influenced by commerce, warfare, world resources, and weather patterns.
Guided discussion question(s): Pick a point in history and discuss why people would want to know about the ocean. Bring up travel for trade, advantages in warfare, or the procurement of fish for food.
What are three reasons to learn the history of oceanography?
2. Want to learn the history of oceanography because:
a. It is connected to the world’s overall history. Understanding the history of oceanography is part of understanding how the ocean shaped the past and may shape the future.
b. It helps you understand how current research questions developed, and how and why people apply marine sciences today.
c. It is interesting. Oceanography grew out of humanity’s desire to explore and discover. It’s about people, not the ocean and test tubes.
Guided discussion question(s): Pick a major historical event and discuss the role(s) played by the ocean. You might choose a military event, like the Boston Tea Party, or an example of exploration, or trade, such as the movement of spices to Europe from China.
What are the four main stages in the history of oceanography?
3 The history of oceanography can be divided into four main stages based on both time and the approach people took in learning about the ocean. They are:
a. Ancient uses and explorations
b. The Middle Ages
c. European voyages of discovery
d. The birth of marine science

A. Prehistory and the Rise of Seafaring
What were the three primary reasons for early civilization to interact with the ocean?
1. The first ocean exploration wasn’t recorded, but archaeological evidence suggests three reasons for early civilization to interact with the ocean:
a. The first was probably to search for food.
b. Trade with other cultures was a second reason.
c. The third reason for early voyages was discovery of new lands.
When was the first recorded sea voyage, and by what civilization?
2. The earliest recorded sea voyage is from 3200 B.C., when Egyptian Pharaoh Snefru brought ships from Phoenicia to Egypt. This suggests that by about 3200 B.C. sea voyages were already commonplace.
B. Ancient Phoenician Explorations and Discoveries
What did the Phoenicians contribute to ocean exploration?
1. Archaeological evidence of shipwrecks in the region probably predates the Phoenician culture itself.
2. Trade motivated much of this trade along the North African Mediterranean coast.
3. The Phoenicians contributed to ocean exploration by establishing the first trade routes. Phoenician trade routes ranged throughout the Mediterranean and as far as Great Britain, but stayed within sight of land, using landmarks by day and stars at night to mark their course.
C. Ancient Polynesian Explorations and Discoveries
Reference the National Science Teachers Association (NSTA) SciLinks Service
Topic: Navigation
Go To: www.scilinks.org
Code: LOP2025
What was the significance of early Polynesian seafaring?
1. Archaeologists think that Polynesian watercraft were similar to dugout canoes, and were propelled by sails and paddles. Outriggers provided stability.
2. On long voyages, two boats were lashed together with crossbeams and a deck.
3. Polynesian voyages of up to 3,200 kilometers (2000 miles) were carried out between 2000 B.C. and 500 B.C., the earliest long distance open ocean travel.
4. These voyages allowed the settlement of islands spread out over about 26 million square kilometers over a period spanning about 1,000 years.
5. The significance of these voyages is that they were the first regular, open ocean long distance voyages beyond the sight of land.
D. Ancient Greek Exploration and Discoveries
How did ancient explorers navigate near shore and in the open ocean?
1. Early ancient explorers stayed within sight of land and used visible landmarks to mark their course, in a method known as piloting, still used by boaters today.
2. Later, as explorers ventured out of sight of land, the sun, constellations, and even cloud formations helped guide open ocean explorers. They may have also used birds and perhaps even smell to learn when they were close to land.
3. The ancient Greeks were the first primary civilization to apply mathematics to navigation. They produced sophisticated maps and recognized that the world was spherical, even though the information was “lost” during the Middle Ages.
What major ocean discovery is credited to the Greek Pytheas?
4. The Greek Pytheas is credited with discovering how to determine north-south position using the angle of the North Star above the horizon. This was one of many mathematical applications the Greeks developed for navigation. He also discovered the connection between lunar cycle and tides in the Atlantic.
What two major contributions are credited to the Greek Eratosthenes?
5. Eratosthenes calculated the Earth’s circumference, and invented the latitude/longitude system. His system was irregular because he altered the lines to go through important landmarks. Later, Hipparchus invented the regular grid system in use today.
