How might space travel and life on another planet change the human body, personality, and culture? This B2–C1 ESL lesson combines space science, human evolution, exoplanets, vocabulary, discussion, and creative writing. Students explore how a generation ship could affect human ancestry, physiology, health, reproduction, and partner selection during journeys lasting hundreds or thousands of years. They then compare possible human adaptations on various planets.

The final activity teaches students to develop a science-fiction character by connecting planetary conditions with appearance, occupation, skills, technology, cultural values, and conflict. Students create a planetary settler and write a three-paragraph character profile, first-person situation, and response. A planning guide, topic ideas, and sample diary entry provide support.

Designed for advanced English learners and suitable for grades 11–12, adult ESL, EFL, science classes, language arts classes, and homeschool, this printable resource encourages critical thinking about genetic engineering, carrying capacity, survival, social control, and the long-term consequences of settling another world. Students practice academic vocabulary within contextual text.
