First page: the lyrics to the song (you can easily find the video on YouTube - if you have the time, tell your students about the original video by Bob Dylan) Second page: students should choose a favorite palindrome and search the web for different ones (at the school, if it has a lab, or as a homework).
It's up to you if you want to use the exercises, just listening to the song is also a lot of fun!
