When I taught second, we did a unit. I used lots of great read alouds . We had them write about their dreams (find a dream/speech bubble) to display in the hall. We also had them make doves-I think there was a template and then they glued cotton balls on it. We hung those from the ceiling. Video clips are very effective for them to really see -Martin Luther King especially.
This looks good:
