Matter exists in three different states. Depending on factors such as temperature and pressure, matter can exist as a solid, liquid, or gas. Under specific conditions, matter has precise freezing, melting, and boiling points. This is the first lesson in a unit about matter.
When matter changes state, its properties change, too. In most cases, volume will increase when matter is melted from a solid to a liquid. Water is an exception, as its volume decreases when melted from ice to water. If matter is not added or removed, its mass will remain the same when it changes state. In this lesson, students will use if/then logical thinking to bridge the science and computer science concepts. This is lesson 2 of 3 in the States of Matter Unit.
