Who hasn't wanted to tie helium balloons to a lawn chair and float up into the sky? Well... I haven't, but that doesn't make me right, just unreasonably cautious. Your students will enjoy reading about one of the early flights of America's favorite lawn chair balloonists, Kent Couch.
This lesson is appropriate for adult English language learners at the advanced level. It has a discussion phase, a vocabulary study phase, a reading/listening passage followed by reading/listening comprehension questions, and an additional enrichment activity. I have used it in individual and large group settings, and found it to be a very flexible and useful resource.
