Matter What is it?

Objective Students will identify three states of matter using particle models.

Matter is:  Stuff that is all around you  Takes up space (volume)  Made up of particles (mass)

Properties of Matter  Matter has many properties  It tells us what things can and can not do  Does it move?  What color is it?  What is it used for?  What size is it?  What shape does it have?

Properties of a Pencil  Look at the pencil  Describe it to your neighbor Size Size Color Color What can it is used for What can it is used for Other Other

3 States of Matter  Solid  Liquid  Gas

Solid  Particles packed together  Closer the particles, the harder it is harder it is  Holds it shape  Particles can’t move much  Has the same volume  Example: rock

Liquid  Particles roll around each other other  Has no definite shape  Fills the shape of the container  Has the same volume  Example: water

Gas  Particles spaced far apart  Fills the container it is in  Has no definite shape  Has no definite volume  Example: air bubbles in soda or smoke coming from a train soda or smoke coming from a train

Activity  Get into groups of 4.  Choose a materials person to get the following: following:  a plastic container.  a bag of marbles  a handout for each student

1. What am I?  Put 6 marbles in your container. container.  Gently slide the container back and forth on the desk. and forth on the desk.  Share with your group what the marbles (particles) do. marbles (particles) do.

1. What am I?  Draw a picture of what the marbles look like on the hand-out. like on the hand-out.  Write down what you see on the hand-out.  Are the particles in a solid, liquid or gas? solid liquid gas

2. What am I?  Put 24 marbles in the container. container.  Gently slide the container back and forth on the desk. back and forth on the desk.  Talk to your group about what the marbles (particles) what the marbles (particles) do. do.

2. What am I?  Draw a picture of what the marbles look like on the hand-out. like on the hand-out.  Write down what you see on the hand-out.  Are the particles in a solid, liquid, or gas? solid liquid gas

3. What am I?  Put 12 marbles in the the container. the container.  Gently slide the container back and forth on the desk. back and forth on the desk.  Share with your group what the marbles (particles) do. the marbles (particles) do.

3. What am I?  Draw a picture on the hand-out.  Write down what you see on the hand-out.  Are the particles in a solid, liquid or gas? solid liquid gas

States of Matter Song States of matter, states of matter, Solid, liquid, gas. Solids stay together. Liquids move where ever. Gases move fast, gases move fast.
