This article explains how some ions have a positive charge and a negative charge. It then states that pure water contains very little ions and does not conduct electricity very well. But if you mix table salt, or sodium chloride, which is an ionic substance, you can conduct electricity. The article also states that when two substances are mixed, they can sometimes make more ions. For example, when you mix ammonia and vinegar (acetic acid), which both have very few ions, the ammonia reacts with the acid in the vinegar and they form lots of ions. This solution conducts electricity very well. In the articles Energy Story, “Conducting solutions”, and in the video Hands-On Science with Squishy Circuits there are similarities and differences. One thing I noticed was that in the video it used a model of how to make your own circuit board using playdough. In Energy Story there is a picture of an atom and there is more information about negative and positive charges. In “Conducting Solutions” it just explains some different solutions, there were no pictures at
