The only time particles of matter do NOT move, is when the temperature is absolute zero (-459 F)
Shape: solid Take the wooden block- place it in the beaker Now place it in the petri dish Can you fit it in the test tube? (Don’t try, just think about it) What do you notice about the shape of a solid-does it change? Solids have a DEFINITE SHAPE
Volume: solid Take the wooden block and place it in the beaker Now place it in the petri dish Could you get it into the test tube? (Don’t try, just think about it) Does the block take up more or less space depending on its container? Has its volume changed? Solids have DEFINITE VOLUME
Examples: Solids Wooden block Marble Add two more examples of solids on your own
Shape: liquid Measure 20 mL of water into the graduated cylinder Pour it into the beaker. Use the funnel to pour it into the test tube What do you notice about the shape of a liquid-does it change in each container? Liquids have NO DEFINITE SHAPE (they take the shape of the container)
Volume: liquid Carefully pour the water from the test tube back into the graduated cylinder How much water is in there? Have you added/subtracted any liquid to the water? Has its volume changed? Liquids have DEFINITE VOLUME
Examples: liquids Water Juice Add two more examples of liquids on your own
Shape: Gas Observe the following: Does the gas have the same shape in each container? Gases have NO DEFINITE SHAPE (They take the shape of the container)
Volume: Gas Observe the following: Does the gas fill the container? Gases have NO DEFINITE VOLUME (They can expand or compress to fill the container) What if I change the size of the container? Does the gas take up a different amount of space?
Think about spraying air freshener or body spray, this fragrant gas will expand to fill a room because gas has no definite volume!
Think about passing gas, this smelly gas will expand to fill a room because gas has no definite volume!

What do we call it when matter changes from one state to the next? MELT VAPORIZE/EVAPORATE FREEZECONDENSE SUBLIMATION
1. A Review of the States of Matter What phase of matter has the particles with the least amount of motion? Solid
2. A Review of the States of Matter What temperature do particles show NO motion? Absolute zero
3. A Review of the States of Matter What type of motion do particles have in a gas state? Very far apart and they move very quickly.
4. A Review of the States of Matter What properties do liquids and solids have in common? Definite volume
5. A Review of the States of Matter What properties do liquids and gases have in common? Both take on the shape of the container they are in.
6. A Review of the States of Matter Infer: A scientist places 25 mL of a yellow substance into a 50 mL container. The substance quickly fills the entire container. Is it a solid, liquid, or gas and why? Gas- takes the shape and volume of the container.
7. A Review of the States of Matter Why can I smell cookies baking in the kitchen when I am on the other side of the house? Gases have no definite volume and will fill the container they are in.
