State Objectives :–States of Matter: Conditions/Identify

The learner will be able to identify states of matter.

Following the presentation, the students will complete a puzzle and a reading comprehension exercise about the three states of matter (solid, liquid, and gas).

Gas

• Has no fixed shape• Has no fixed volume• Made of particles that move rapidly • The particles also have large spaces

between them in comparison to solids and liquids

Examples of Gases are

• Steam• Oxygen• Carbon dioxide• Smog• Tear Gas• Helium

Liquid

• Has no fixed shape• Has a fixed volume• Particles move past one another easily• Particles are fairly close, but not in a neat

even arrangement as the particles in a solid are

Examples of Liquids are

• Orange Juice• Water• Soft drinks• Milk• Rubbing Alcohol• Vinegar

Check out the following Site on Liquids :

Solid

• Has a fixed shape• Has a fixed volume• Particles are arranged in a tight, regular

pattern• Particles move very little

Examples of Solids are

• Ice• Frog• Cheese• Bricks• Wood• Popcicle
