Cell City

I found a few things that may interest others.

One of the lessons I found compares a cell to a city with a powerplant, city hall (nucleus) etc. It's basic but helpful. I also found a city rug (my kids') and thought I could have the students label it to go with the city. I also found a website: http://www.cellsalive.com/toc_cellbio.htm
It has cool graphic and a cell model.
