This PPT provides a short and concise summary of what Star Trek is about. Given the cultural impact that the Star Trek Series has had on people in North America and beyond in the last 40+ years I feel that this is a pop culture subject that needs to be taught; especially for ESL learners and foreign students.
The Introducing Star Trek ppt is only a foundation. You as the teacher need to add other activities to this based on what you need to teach to your students. I originally did this as an English corner many years ago.
One activity that I recommend is that you have your students watch the Original Series episode "The Doomsday Machine" and from there have a discussion about the theme of that episode.
The PPT is like tomato and cheese pizza; what you want to teach and how you want to do it are the toppings. This lesson can come in many different flavors and the only limit to it is your imagination and the needs of your students.
This will be really helpful for you. If you ever do this as a lesson, let me know, give me feedback and if you need help from me contact me ASAP. Good luck and have fun with this.
