Catalyst (Left Page) What is an observation? What is an inference? TURN IN YOUR MULTIPLE CHOICE QUESTIONS IF YOU HAVEN’T ALREADY! Matter and States of Matter

2 Demos For each of the two demos, make two observations and an inference about what is happening (left page). Matter and States of Matter

 Matter is anything that takes up space  Matter is everything around you.  Matter is anything made of atoms and molecules.  Matter is anything that has mass

 MATTER: anything that has mass and takes up space

Matter Anything that has mass and takes up space Matter and States of Matter

 Matter comes in three main states (+ two other ones):  SOLID  LIQUID  GAS

Matter Anything that has mass and takes up space Solids, liquids, gases Matter and States of Matter States of Matter

 What is volume?  Volume is how much space something takes up.

Matter Anything that has mass and takes up space Solids, liquids, gases Matter and States of Matter States of Matter Volume How much space matter takes up

 In your notebook (left):  Name some things that are solid  What are some characteristics of that all solids have?

 Have a definite shape and volume  The particles are tightly packed together in a fixed position.  Particles are not free to move very much.  Particles are moving but because they are so tight, they seem to vibrate

Matter Anything that has mass and takes up space Solids, liquids, gases Matter and States of Matter States of Matter Volume How much space matter takes up Solids Definite shape and volume -Particles tightly packed (compact) -Particles moving  creates vibration

 In your notebook (left):  Name some things that are liquid  What are some characteristics of that all liquids have?

 Have a definite volume but not shape  Can take the shape of the container that holds it.  Still has the same volume because it takes the same amount of space.  Particles close together but are more free to move in relation to each other.

Matter and States of Matter Liquids Definite volume but not shape -Particles packed together but can move around -Liquids take shape of container

 In your notebook (left):  Name some things that are gases  What are some characteristics of that all gases have?

 Have a NO definite shape or volume  Particles are farther apart  Particles move faster and more freely  Particles tend to expand in all directions

Matter and States of Matter Liquids Definite volume but not shape -Particles packed together but can move around -Liquids take shape of container Gases NO definite volume or shape -Particles are far apart - Particles move and expand in all directions

 Take 2 minutes to write a summary  Make sure to include the following: ▪ What are the 3 states of matter ▪ What are the particles doing in each state of matter
