Awarded To: Carolina: Matter Cycling and Energy Transfer in Lake Ecosystems

VERIFY

Students begin with the phenomenon of a fish kill that occurred in Lake Erie in late summer. Students strive to make sense of this phenomenon by gathering evidence through investigations, readings, and digital resources. As students move through the lesson, they conduct investigations where they use system models to collect evidence about the roles of producers and consumers in an ecosystem; they learn how abiotic factors, such as nutrient levels and temperature, can cause changes in the ecosystem; and they explore the relationships between ecosystem components. Throughout the investigations, students develop and revise their claim surrounding the causes of the fish kill. At the conclusion of the lesson students will use the evidence gathered to construct a final explanation for how changes in the lake ecosystem caused changes in matter cycling and energy transfer that, in turn, lead to the fish kill.

Kit materials equip 10 groups of students and include digital resources. Note: Order the kit with perishable materials included or with a voucher to request delivery of perishables later at your convenience. Contact Carolina or return the voucher to request delivery of perishables. Residents of AK must apply for a permit from your state game and fish department to receive pond snails.

Learning Performance Expectations

• Ask questions to investigate the causes of changes in balance in a lake ecosystem that led to a fish kill.
• Develop a model that illustrates the interrelationships among biotic and abiotic components of a lake ecosystem, including boundaries, initial conditions, and inputs and outputs of matter and energy, as they move through the system.
• Develop, revise, and use a model, based on evidence, to illustrate how matter and energy flow through trophic levels in a lake ecosystem and how changes in abiotic and biotic components caused the system to become unbalanced and led to a fish kill.
• Plan and carry out an investigation to gather evidence for the causes of the changes in matter cycling and energy transfer in the lake ecosystem that led to a fish kill.
• Construct an explanation, based on evidence, for how changes in abiotic and biotic components of a lake ecosystem caused changes in matter cycling and energy transfer and led to a fish kill.
• Construct an explanation, based on evidence, for the role of photosynthesis and cellular respiration in the cycling of matter and transfer of energy in the biosphere.
