Grades 3
The Chesapeake Bay is home to millions of crabs and oysters, which can be harvested for economic and food industry purposes. The best time of year for the harvest is determined by weather patterns, as well as by the growth and survival conditions of the crabs and oysters. We will explore these topics and concepts in this lesson.
Teacher's Guide and Related Standards
I can explain how various climate and weather patterns can affect conditions of the Chesapeake Bay and how communities adapt to these effects.
Oyster Facts
In this activity, students explore various facts about oysters. One important fact mentioned in the article is that oysters breed in the summer and become adults in the winter. Discuss how this evidence can be used to support the argument of when oysters should be harvested in the Chesapeake Bay?
Could Blue Crabs Weather a Changing Climate?
Watch the video and read the information about blue crabs and the weather conditions that are best for their growth and flourishment. How does this information help us understand the times of year when crabs are most often caught and used for food?
Pounds of Oysters and Crabs Harvested Graph
Analyze the graph with students. Relate the patterns shown in the graph with what was described in the video - “crabs were not popular in the past until refrigeration technology advanced, so that crabs would spoil less and could be transported easily.” Further, have students interpret the trends in oyster harvesting.
