Who do you think laid the foundation/discovered most of that "knowledge?" It wasn't you or your kid.
Could your kid: 10 Describe how a mercury light works; 2) Describe how a doorbell works; 3) Describe the differnece between a wet cell/dry cell battery.
Only 3 of about 20 questions on a test I had to take in l954. It was a 9th grade General Science test.
Well, I'm not certain that he can describe the mercury light thing, the other two are a shoe in. He was taught by the Franciscan Nuns.
I would call him and ask him, but this is finals week. One more semester and I'm and I'll be disconnected from the tuition leach.
