In these ESL lesson plans for adults and teens, students watch a video and do a listening exercise about a marijuana course at Oaksterdam University. It includes discussion questions and conversation activities about marijuana and universities. Students also learn some important vocabulary terms related to these topics. The grammar exercises feature the difference between say vs tell, and informal contractions (cuz, kinda, gonna, etc). In the cooperation activity students can give a presentation, write reviews, or create a new course topic.
