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 Laws of Conservation and Photosynthesis
The Laws of Conservation and Photosynthesis

The laws of conservation of matter and conservation of energy are demonstrable through an examination of the photosynthetic process. This informational module affords 8th grade physical science students the opportunity to examine the relationship between matter and energy as evidenced by transformations that take place during photosynthesis. The student work will lead to a deeper understanding of the laws of conservation drawn from students' previous knowledge of a biological process. After researching texts on photosynthesis, the law of conservation of matter, and the law of conservation of energy, students will answer Template Task 13 by writing an informational essay that describes how the photosynthetic process can be used to demonstrate both the law of conservation of matter and the law of conservation of energy.
