Biodiversity

Earth is rich with an amazing variety of life. Is it important to preserve this biodiversity? This introductory writing assignment for a life science class focuses on introducing 7th grade students to the concept and importance of biodiversity. After reading articles on biodiversity, students write a report that defines “biodiversity” and explain its importance by following Template Task 11.

The Effect Algal Blooms Have on Marine Ecosystems
The Effect Algal Blooms Have on Marine Ecosystems

Population balance in marine ecosystems is crucial to sustaining a healthy system. The results of human activities, such as fertilizer run-off from nearby farmlands into the Mississippi River, can impact energy webs by offsetting predator-prey relationships. Seventh grade life science students are required to use scientific articles to research the cause and effect of algal blooms off the coast of the U.S. and write a letter to the Environmental Protection Agency (EPA) to inform the agency of the problem as well as suggest possible solutions. This informational module poses the project scenario to students by using Template Task 25.
