Some mighty good science was done with next to no cash outlay. And the field trips are soooo much fun.
I was recently asked about an enjoyable learning experience. I recalled sitting in a big chair with a pile of books, reading Alvin Plantinga and making cryptic notes to myself in a little notebook. All of the statements I needed to consider were either in the books or in my brain and the laboratory setup was the mental equipment God gave me. And when you have to get up and go you can take the game with you, in the car, at work, or standing in line somewhere, all the pieces and parts fit between your ears.
