Hi! I'm Carl Nelson and this is my collection of science activities, videos, photos and other stuff I find interesting. After completing my masters degree in Physics I fell into the world of informal education. I've worked in science centers for the past 16 years and am currently the Chief Scientist and Exhibits Director at Imagination Station, a science center, in Toledo Ohio.
