Exit ticket · What Is an Environmental System?

Exit Ticket

Exit Ticket: Students respond on an index card or sticky note before leaving:

1. What is a system? Students write their own definition, using the anchor chart as a reference if needed.

1. Why do parts depend on each other? Students explain interdependence: “If ___ were removed, then ___ would happen because ___.”

1. Name one input and one output. Students identify from their own diagram, using proper vocabulary terms.

Answer Key / Look-Fors: (1) A group of parts that work together and depend on each other. (2) A complete if/then/because statement (e.g., “If the bees were removed, then fewer plants would make seeds because flowers would not be pollinated”). (3) Correct input (sunlight, water) and output (oxygen, fruit, waste) from their diagram.

Expanding Circles — how does this connect to… Ask: “How does your system connect to you → your classroom → your school → your community → the world?” Students can share with a partner before or after writing.

Formative Assessment (group students using each student’s System Diagram and the exit-ticket definitions of a system, its inputs, and its outputs): Meets (3): Diagram shows at least four parts, one input, one output, and two interaction arrows with vocabulary.

Approaching (2): Diagram shows parts but inputs/outputs or interactions are missing.

Not Yet (1): Diagram is a list of objects with no connections — reteach with the garden anchor chart and one modeled arrow.
