I'll be happy if my sixth and seventh graders can find answers to science questions on the Internet and comprehend them (they usually can). Some of the school-suggested Internet knowledge sources are really pretty good. Mastering the subject is for grad school.
There are all levels of mastery and I don’t think that you understand the type of sources that they will use. It will be more like the short science essays that you would read for an SRA reading lab and I am not talking about sixth and seventh graders. If you are content with your kids learning science from short bytes of information on the internet instead of a lab science, go for it.
One example that was given of a feminized science course at Yale, was the history of science. The girl who wrote the article for the college newspaper was majoring in feminist studies and the history of science. She didn’t need to take even one real science course.
