I figured I would give all of you a chance to share. I am presenting at the Hoosier Association of Science Teachers this week. The topic is Human Impact on Groundwater. I will be utilizing a groundwater model and showing a presentation on some of the job sites I have worked on as an environmental consultant. If anyone would like to share a lesson I would be happy to pass it on. This is a K-12 conference, however don't let that limit you. As you all know any good teacher can adapt material to fit their classroom. Thanks Eric Ruckert Associate Instructor IPFW WNHS
