Description

Mar de plástico is a Spanish 4 CI curriculum unit from the Huellas 2 curriculum sequence designed to build proficiency through environmental awareness, global responsibility, and meaningful comprehensible input. In this 13‑day unit, students explore plastic pollution in the world’s oceans, examining how single‑use plastics and synthetic materials impact marine ecosystems and sea life.

This proficiency‑based Spanish 4 curriculum unit targets Goal 14: Life Below Water from the United Nations Sustainable Development Goals and supports interpretive, interpersonal, and presentational communication. Students engage with background information, readings, visuals, and discussion to understand the causes and consequences of ocean pollution. As the unit progresses, learners move from awareness to action, using Spanish to propose solutions, reflect on personal habits, and consider ways to create change within their own communities.

Mar de plástico can be used as a stand‑alone Spanish 4 thematic unit or as part of the full Huellas 2 curriculum sequence. The unit is designed with flexibility in mind, allowing teachers to move at their own pace and extend learning through optional community outreach or action projects.
