How about a lesson on figurative language. You could do simile and metaphor pretty easily.
For simile and metaphor you could listen to songs such as Firework by Katy Perry, The River by Garth Brooks, or The Grinch (not really the right season). You could have pairs of students illustrate each metaphor or simile and act it out as well. Each person is one half of the comparison, so they always understand that similes and metaphors are comparisons of at least two things.
Here's the first line from "Firework"
"Do you ever feel like a plastic bag
Drifting throught the wind"
They listen to the song, then the pair that picks this would have a picture, illustration, whatever art project you choose showing a plastic bag in the wind and a picture of a person next to it (to show what is being compared). Then have them act out a plastic bag as well as show what it feels like to be lost and confused using facial expressions. Then the simile will come alive for them and they will understand that it is standing for an emotion.
Good luck, hope that helps
