This question is directed at public schools, which make up the vast majority of the U.S Schooling system, Please disregard any and all Religion/Private schools as they can legally teach any religion/atheism etc.
In a lot of states in the southern states, there are a vast number of errors being taught/forced upon children, in most cases illegally, that can vastly affect the rest of their life.
Alot of southern states have a leaning towards religion rather then atheism, as can be shown in stats. The majority of northern, or east-coast and west-coast northern states which make up a majority of the pop. have declining rates of religion, yet the south continues to remain stable.
There are often cases of Children reported being taught about the bible/god in public schools. This is only legal if it is 1) Optional 2) Equally balanced out with other religions, and an atheist POV. Technically speaking The first ammendment bars any public schooling establishment from forcing kids into religion classes. And the United States technically has no official religion(Look it up).
Most physics/science classes only cover proved scientific theories such as the big bang, evolution, and to a broader extent atheism for 1 lesson max, whereas they focus on creationism.
