Another classroom activity, this one using a scenario of investigating groundwater contamination at a gas station to reinforce some basic concepts about hydraulic head and groundwater flow. It’s based on a lab by Karen Kortz at CCRI which I stumbled across on the SERC website. I expanded the grid a bit, put together a slick … Continue reading
Of troublemakers, priorities, and forgotten battles worth fighting

Grumbles about Fox News, the Daily Mail, or [insert politician here] build to a low roar of background frustration. The questions are obvious. “Why do these people think … Continue reading

This is not the first time this site has … Continue reading

Opponents commonly feel that if they can just show that there are problems with the consensus explanation, their preferred explanation will come … Continue reading

In his words from a 1974 commencement speech: In the South Seas there is a cargo cult of people. During the war they saw airplanes land with lots of good materials, and they want the same thing to happen now. So they’ve arranged … Continue reading
