This poster is to be used in conjunction with a teacher, so it doesn't quite make sense standing alone. There's a house with several drains leading to a pipe that goes to a sewage treatment center. Now imagine the 7 squares are blank. With the teacher's help, kids need to figure out the 4 main stages of sewage treatment, and to learn about 3 of the many microbes that help break down sewage. Those square images will be printed separately and mounted with velcro on the back, so they can be adhered to the poster as their topic comes up.
