Part(icles) of Your World

The video explains that everything is made of matter, which consists of particles. Matter exists in three states: solid, liquid, and gas. The properties of these states depend on the arrangement and movement of particles. The video provides examples of how matter can change states, such as a candle melting or water boiling. It concludes by emphasizing that matter is always present, regardless of its state.

What is the fundamental building block of matter?

• Cells

• Molecules

• Particles

• Atoms

How do particles behave in a solid state?

• They are tightly packed and do not move

• They are far apart and move rapidly

• They slide past each other

• They move freely

Which state of matter allows particles to slide around each other?

• Solid

• Liquid

• Plasma

• Gas

What happens to the particles of a liquid when it is heated?

• They become tightly packed

• They form a solid

• They move slower

• They move faster and spread apart

What is an example of a gas turning into a solid?

• Ice melting

• Water boiling

• Steam condensing
