How Crystals Work - TedEd

Below are supplemental materials to my TED-Ed lesson on how crystals work. These materials are useful for elementary to university level science education.

The movies show the growth of various crystals from an evaporating solution. Solutions are saturated with NaCl (halite or table salt), KCl (sylvite, or “salt substitute” found at the grocery store), or sucrose (table sugar) solutions, or a mixture of these solutions.

There is a progression of topics presented, so it is suggested the topics are viewed in the order presented below.
