In this ESL lesson plan for adults and teens, students watch an informational video about quantum computing and what might happen if working quantum computers became widely available today. It includes discussion questions and conversation activities about computer science, personal data, cybersecurity, climate change, medicine, and the possible benefits and risks of advanced technology. Students learn important vocabulary terms and phrases from the video, including duality, ulterior motives, game-changer, sphere, cryptography, and let alone. The post-viewing section includes activities on video vocabulary, prefixes and suffixes, homographs, and intensifying prefixes such as super-, hyper-, mega-, and ultra-. There are additional speaking tasks included, as well as a quiz and review section with a bonus activity.
