This covered Edison, Labor Unions, and Prohibition, pages 184-194 in The American Story by Jennifer Armstrong.
For our art activity, we made a newspaper and kids sold it, like the Newsies (news boys) who organized a union near the turn of the last century.
Our paper was a big hit!
For our active activity, we did a smuggling game based on Red Light Green Light.
I was the "catcher" looking for smugglers and I stood at one end of the yard with the kids at the other end. Every time I looked away (searching for smugglers) they moved forward, and every time I looked back, they froze.
For our snack, we were going to have root beer floats, but I had also made peanut butter cookies, and the kids had so many of those, we decided they didn't need more sugar.
