A night under the Swiss stars: Modals for deduction

This lesson introduces a unique Swiss concept — a hotel with no walls or doors, where guests sleep directly under the stars. Students practice Modals for deduction (must, might, could, can’t) to make guesses and draw conclusions about unusual situations, design, and travel experiences.

GRAMMAR PRACTICE

Learners focus on must have, might be, could be, can’t be and similar structures to express certainty, possibility, or impossibility. Activities include gap-fills, sentence transformations, and scenario-based guessing tasks.

VOCABULARY BUILDING

Students expand vocabulary related to accommodation, design, and hospitality, including words for luxury, comfort, scenery, destination, resort, architecture, sustainability, innovation. Phrasal verbs: check in, check out, set up, look around, try out, take in.

SKILLS & ACTIVITIES

Learners read about the open-air hotel, discuss advantages and challenges, and role-play as guests or hosts. Speaking tasks include describing travel experiences, evaluating unusual hotels, and debating whether such concepts are sustainable or just a novelty.
This ready-to-use ESL lesson plan is designed for adults, combining grammar, vocabulary, and communication tasks to build both accuracy and fluency.
