Why is it that most science classroom desks seem to be built out of wood, but have the desk area covered in some black material? I'm talking about desks like this:
Without knowing an answer to the basic question, it's hard to flesh out my other questions, but here's a basic list:
- Is that black material inert in some way, so as to not react to any of the chemicals a student might use in class? Is it just easy to clean?
- Why the standardization? I've seen these desks in public and private schools in a number of different states in the US
- Is this US-specific? Do other countries have their own standard desks?
(Note: I'm not sure that this is the correct StackExchange website to post this on, so I'm open to suggestions. It seemed to be the closest fit to education/school. There are some sites for specific scientific disciplines, but I thought someone in academia in general might know an answer)
