Solids, Liquids and Gases
By Kathleen Amy
Solids• One of the major states of
matter• A solid does not take the shape
of its container• Atoms in a solid are tightly
bound together
Liquids• Second major state of matter• Liquids can flow• Liquids take the shape of their
container• Atoms in a liquid are loosely bound.
Gases• Third major state of matter• Gases have no shape or size of
their own• Gases are all around us.• Gas particles can move past
each other.
Changing of Matter• All matter can change from one
state to another.• In order for matter to change
form, it may require very low temperatures, very high temperatures, or high pressure.
How to Change Water to a Solid, Liquid, and
Gas• Water can be changed to a solid when it reaches its freezing point
• Water can be changed to a liquid when it reaches its melting point
• Water can be changed to a gas when it reaches its boiling point.
Content Standards• First Grade Physical Science1. Materials come in different forms
including solids, liquids, and gases.A. Students know solids, liquids, and gases have different properties.B. Students know the properties of a substance can change when the substance is heated, cooled, or mixed.
