Learning Objectives

Aquatic Communities is the Aquatic Science STEM curriculum Lesson 5 that includes relevant science topics in 11 videos: What are some of the basic survival needs of all living things? What is a population? What is a community? What is habitat? Why is it important? Why must organisms compete for resources? What is carrying capacity? What is a niche? Why is it important? What are invasive species? Why are they a problem? What is the source of energy for aquatic communities? How does energy circulate among organisms in an aquatic community? What is a food chain? What is a food web? What is an energy pyramid? What is a trophic level? How do predator and prey species keep species populations in balance in aquatic communities? What is natural selection? In what ways might food webs, food chains, and predator-prey relationships be different in a pond, an estuary, and the Gulf of Mexico? What happens when one piece is altered or removed?

About This Project

Aquatic Science Lessons with Dr. Rudy Rosen is an on-line video curriculum arranged into 13 lessons. Each lesson covers a major subject area and is broken down into short sub-topic video presentations. These short videos covering important aquatic science topics can be used in teaching instruction or for self-education. A comprehensive teaching guide and enhancements can be downloaded FREE here.The teaching textbook is published by the Texas A&M University Press and can be obtained here.
