Habitable Planets | CEFR B2–C1

Bring astronomy into your classroom with an engaging lesson on habitable planets, exoplanets, and the search for extraterrestrial life. Students build academic vocabulary, develop objective scientific writing, and apply critical thinking through reading, discussion, and creative problem-solving.

This resource explores the conditions required for life beyond Earth, including the habitable zone, liquid water, planetary atmospheres, orbital stability, and the building blocks of life. Students investigate how astronomers search for exoplanets, examine current scientific evidence, and consider how alien organisms might adapt to different planetary environments. They then apply these concepts by writing a scientific Captain’s Log and designing life forms adapted to fictional worlds.

This lesson includes:

15 academic vocabulary words with contextual practice
Two nonfiction reading passages
Space and astronomy vocabulary
Objective scientific writing task (Captain’s Log)
Creative adaptation and problem-solving activities
Reading comprehension and vocabulary exercises
Answer key and model writing response

Ideal for adult learners, upper-intermediate and advanced English classes, conversation courses, private tutoring, academic English, science-themed lessons, astronomy, exoplanets, critical thinking, reading, writing, and discussion.
