THE STATES OF MATTER
BY: IMANI SINGLETON * MRS. ESSIC'S 2ND GRADE CLASS*
SOLIDS
Solids are one of the three states of matter that have a true shape that is not easy to change. Different solids have properties such as stretch, strength, or hardness that make them useful for different jobs. Most solids are made up of tiny crystals with strong forces that have a tight close position to keep them firm. Some solids can be hammered or smashed into many different shapes without breaking. Some solids can be heated up to change shape too. The desks on my background are solid.
PROPERTY #1
SOLIDS CAN BE HARD
PROPERTY #2
SOLIDS CAN STRETCH
PROPERTY #3
SOLIDS HAVE STRENGTH
LIQUIDS
Liquids are one of the three states of matter that do not have a true shape. The flow of liquids can take on the shape of whatever container it is in. Liquids have volume, which is the amount of space it takes up. When liquids are poured from one container to another the volume stays the same but the shape changes depending on the container. There are weaker forces in liquids than in solids, this is what causes them to move more easily. Some liquids can change shape by being frozen to make them solid and being heated to make them gases.
PROPERTY #1
LIQUIDS HAVE NO TRUE SHAPE, THEY TAKE THE SHAPE OF CONTAINERS
PROPERTY #2
LIQUIDS HAVE VOLUME
PROPERTY #3
LIQUIDS CAN FLOW EASILY
GASES
Gases are one of the three states of matter that are all around us, but most gases are invisible. Like liquids, gases can flow but, unlike solids or liquids, gases will not stay where they are put. Gases have no set shape or volume, and they spread in every direction to fill whatever container they are put into. If the container has no lid, the gas can get out. When water vapor or steam cools it can form droplets that can change into a form of liquid.
PROPERTY #1
GASES MOVE VERY QUICKLY
PROPERTY #2
GASES TAKE THE SHAPE AND VOLUME OF ITS CONTAINER
PROPERTY #3
GASES CAN BE INVISIBLE
