Matter: : 

Matter: It’s what the world’s made of.

What do you know about matter? : 

What do you know about matter?

Solids : 

Solids Solids hold their own shape. Solids have weight. Solids take up space.

Liquids : 

Liquids Liquids take the shape of their container. Liquids have weight. Liquids take up space. !

Gases : 

Gases Gases spread out to fill the entire space given. Gases have weight. Gases take up space.

Plasma : 

Plasma Lightning is a plasma. Used in fluorescent light bulbs and Neon lights. Plasma is a lot like a gas, but the particles are electrically charged.

STATES of matter? : 

STATES of matter? What would it take for matter to move from one state to another?

Energy determines the state! : 

Energy determines the state!

Particles in Solids: : 

Particles in Solids: Are packed tightly together Have very little energy

Particles in Liquids: : 

Particles in Liquids: Are loosely packed Have medium energy levels

Particles in Gases: : 

Particles in Gases: Move freely Have LOTS of energy

Particles in Plasma: : 

Particles in Plasma: Are electrically charged Have EXTREMELY high energy levels

Mixtures may be in different phases : 

Mixtures may be in different phases Solid? Liquid? Gas? Plasma?

Add or Subtract Energy. . . : 

Add or Subtract Energy. . .

What will happen? Why? : 

What will happen? Why?

Solid + Energy = ? : 

Solid + Energy = ? When energy is added to solids, they become liquids! Examples?

Liquid + Energy = ? : 

Liquid + Energy = ? When energy is added to liquids, they become gases! What examples can you think of?

Changing States : 

Changing States There are several names for matter changing states: State change Phase change Physical change

So, did we get something new? : 

So, did we get something new? Ice cream and melted ice cream? Chocolate and melted chocolate? Ice, water, and water vapor? Steel and molten steel?
