Over at Allen MacNeill's class blog, there is a blog written by Hannah where she claims, "Scarcely anything in science will ever be proved or disproved."
A molecular biologist has joined the comments section to "correct" Hannah:
This is plainly false unless you are proposing new definitions for "proved" or "disproved." Do monkeys reproduce sexually? Yes. Science proved that. Do some bacteria reproduce by fission? Yes. Science proved that. Can white light be separated into its component colors? Yes. Science proved that. I could go on and on and on and on.
Let me give you some friendly advice, Hannah, at this early stage in our discussion. Re-read every sentence you type and ask yourself if you are distorting the truth to make your argument more compelling. If the latter, then rewrite the sentence. Hopefully, I do not need to explain why this is good practice.
Now, if you go over to this website and work your way through the links, you'll eventually find this page on Concepts for Grades 9-12. Scroll down to the section on "Nature of Scientific Concepts." And what do you find?
Science does not prove or conclude; science is always a work in progress.
The molecular biologist also used PubMed to find many places where scientists use the term "prove." Sure, just as the same type of search will uncover many places where they also use the term "theory."
