Crystal Gardens/Chem-Mystery

Eliminate the mystery in chemistry!

Chemistry is the science that investigates materials, what materials are made of, how they are made and the changes they go through. Chemistry is the study of substances. We observed that substances can be solids, liquids or gasses. Physical change happens when mixed substances do not form something new. Chemical change happens when mixed substances form something new. Some signs of a chemical reaction are a new solid or gas or a change in temperature or color.
