Standards Alignment
Learning in this module can be extended using the A Warming Gulf of Maine: Investigating Impacts on Predators and Prey module.
Both of these modules work well as a compliment to learning that happens during the onsite LabVenture Program. Consider using one or both units as follow-up learning experiences to the visit.
Lesson 1: Meet the Species In Our Ecosystem
In this lesson, students are oriented to the Gulf of Maine and research some of the species that call it home. Special attention is given to plankton as the base of the marine food web. At the end of the lesson, students synthesize their learning by drafting a model of the relationships among the species using a food web. This work sets students up for following lessons that dive deeper into models of energy and interdependence throughout the ecosystem as well as research being conducted by scientists studying the health of the ecosystem in the Gulf of Maine.
Lesson 2: Modeling Energy Flow in a Marine Food Web
Students engage with an embodied modeling game that explores energy flow in a simplified marine ecosystem beginning with the sun and then working its way through multiple trophic levels from phytoplankton to zooplankton to consumers further up the food web. Students also consider how a natural system is represented by a model.

Lesson 3: Data Stations - Warming in the Gulf of Maine
In this lesson, students will move through a series of data stations to take a closer look at models and research about ocean warming to directly address our three research questions: What is happening in the Gulf of Maine? How do we know? and Why does it matter?

Lesson 4: Modeling a Marine Food Web in a Changing Climate
In this lesson, students revisit the embodied modeling game, applying new information about the impact of warming on plankton populations. Students then take some time to reflect on how models can be used as tools to initiate change and develop solutions, highlighting the progress we have made towards addressing global warming as a result of past climate projections.

Lesson 5: Spreading the Word and Planning for the Future
In this lesson, students synthesize their learning in a final product taking a form of their choosing. Students will address the key questions explored in this module, using research and evidence to support their thinking. A note catcher is provided for students to outline their thinking and a checklist and rubric are available for students to ensure they have included all pieces in their final product. Suggestions for the final product include making a PSA, slideshow presentation, research paper, children’s book, board game, writing a song and so on. As an exceeds option, students suggest research-based solutions to address problems caused by warming in the Gulf of Maine.
