Students participating in this lesson will collect, observe, and record particulates from the air to contrast visible and invisible air pollution. They then complete a simulation of the damage due to acid rain to illustrate invisible pollution. The lesson plan provides essential elements, objective, focus, a list of materials, background information, procedure, and ideas for enrichment.
