Huellas 2.3 La biodiversidad y la conservación

Biodiversidad is a Spanish 4 CI curriculum unit from the Huellas 2 curriculum sequence sequence designed to build proficiency through authentic media, environmental themes, and meaningful comprehensible input. In this 10‑day unit, students take a virtual journey into the rainforest, exploring ecosystems in Panama and the Amazon Basin while learning about biodiversity, forest layers, and the organisms that inhabit each part of the rainforest.

This proficiency‑based Spanish 4 curriculum unit supports interpretive, interpersonal, and presentational communication as students engage with authentic videos filmed inside the rainforest, informational texts, and guided discussion. With Cris as a guide, students compare familiar forests with tropical rainforests in Central America and South America, developing language to describe environments, explain ecological relationships, and reflect on human impact. The unit also connects to global issues and the United Nations Sustainable Development Goals.

Biodiversidad can be used as a stand‑alone Spanish 4 thematic unit or as part of the full Huellas 2 curriculum sequence.
