Teacher Notes (by section)
In this section, students will activate prior knowledge about Maryland's blue crabs. They will explore the life cycle of the blue crab, and they'll learn how to use a concept map to organize ideas and related concepts.
Tip: Use legal size paper or larger for student concept maps to allow extra space for students with large handwriting or for students who may wish to add illustrations to their maps. There are also a number on student-friendly online tools for concept mapping that you may wish to use as an alternative to paper maps.
Have students research and explore the physical characteristics of the blue crab and how males are distinguished from females.
In this section, students will learn about the value of buying local crabs and the work of watermen and waterwomen. They will begin populating their concept maps about Maryland's crab industry.
Tip: Remind students that the example concept maps represent one way of organizing the information and that their maps may be organized differently and include different wording. For students who may struggle with concept mapping, they may use the samples as a guide.
Before proceeding to the next section, have students discuss the benefits of buying local crabs. Ask them to share any personal experiences with eating Maryland crabs or crabs from other regions and note any advantages or disadvantages.
