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.

The Great War: Evaluating the Treaty of Versailles

Students study a variety of primary sources, maps, and supporting documents concerning the post-war peace process, developing a context for evaluating whether the treaty was viable and fair. Students also consider complex questions surrounding historical causality and responsibility. This argumentation module is written around Template Task 2 for a high school social studies class.
