Okay, so did you read the link? Did you get a test like that one say in 1953????
But, I had a general science class in 1954 and some of the questions on a 25 question test were: Explain how a wet cell battery works; explain how a mercury light works; explain how a doorbell works. Only 2 kids passed...one was later our class valdictorian and the other our salutatorian. I was neither. LOL!
The teacher was so mad he told us we would have to take it until we passed...he quit giving it after seven more times. I never did pass it. I still don't understand how a murcery light works and only care that it comes on at dusk. :)
