How do we know about atoms if we can't actually see them? This is probably the most common question students ask when they study chemistry. The Shedding Light on Atoms series answers this question as well as many more. Using amazing demonstrations and animations we take students on a journey of discovery to explain not just what we know about atoms, but how we know what we know about atoms!
