Unit Overview
"Diving: Exploration and Conservation of Underwater Ecosystems" is a unit that explores the sport of scuba diving and the responsibility that scuba divers have to protect and conserve the coral reef ecosystem. As primarily a math and science unit, students will examine the impact of pressure on gases and will use the physics gas laws to explore concepts dealing with volume, pressure, density, and inherent lift. Once a thorough understanding of the laws has been attained, students will relate and apply their new knowledge to the tables and charts used for recreational diving. This will allow them to safely and successfully plan dives while taking into account factors such as depth, physical exertion, nitrogen absorption into the bloodstream and tissues, oxygen toxicity, and water condition. Students will learn how to calculate the lift required to remove objects from the ocean floor as well as exploring the physiological effects of diving on the human body.
In addition to the focus on the sport of scuba diving, students will also delve into a study of coral reef ecosystems. They will discover why coral reefs are essential for our survival and will investigate the reasons that these natural treasures are endangered. Students will learn about the methods scientists use to collect coral reef data and will examine things they can do to help conserve this resource.
The goal of this unit is actually twofold. First, it is to introduce students to an exciting and awe inspiring sport that relies on the application of science and mathematics principles if it is to be enjoyed safely. Students will see connections between the real world and the math and science they learn everyday. In addition, the unit is designed to help students learn to value and appreciate the coral reef ecosystem and to empower them to make changes that will play a role in conserving this valuable resource.
