DO NOW  Which of these things are made up of matter?  You  Miss Kerschen  Your lunch  Your locker  The rain  Air

Bar Graph Review  Simple Bar Graph  Grouped Bar Graph  Composite Bar Graph  Histogram

Matter  Everything is made up of matter!  Matter is anything that has volume and mass  Even air is matter – even though you can’t see it  That’s why the paper towel stayed in the cup the first time  The “empty” space in the cup was filled with air  When the hole was added, it allowed the air to escape and water took its place

BrainPop  Tim and Moby are going to tell us about the different states of matter.

Candle Observations  Miss Kerschen will walk around the room with a lit candle  Make as many observations as you can – about what you see, what is happening, etc.  Make sure long hair is tied back and long sleeves are pushed back  Any inappropriate behavior will not be allowed  Your classmates deserve a safe environment

Candle Observations  What types of things did you observe?  Specifically, what was happening to the candle?

Candle Observations  The wax in the candle was changing states – from solid to liquid and back to solid  The temperature that causes matter to change from solid to liquid is called the melting point  If we got the candle really hot, it would turn from liquid to a gas  This temperature is called the boiling point  Water isn’t the only thing that boils!  This process is called vaporization  When the liquid wax cooled, it turned back into a solid  This is called freezing

Class Matter  We will show how adding heat speeds up particles in a substance  As the particles speed up, the substance changes from solid to liquid to gas

Class Matter  Everyone stand up and move to the side of the room  Stand as close as you can to each other and move very slowly  You’re a solid!  Now, start moving around half of the room a little faster – You’re melting!  You’re a liquid!  Next, walk around the entire room quickly – You’re vaporizing!  You’re a gas!

Class Matter  Now the class will start cooling off  Walk slower and move toward the side of the room – you’re condensing back into a liquid!  Walk very slowly to the side of the room and stand very close together – you’re freezing back into a solid!  Adding heat speeds up particles  Cooling slows down particles

Flow Chart & Word Scramble  Complete the two worksheets about the states of matter and how the particles move.

For Monday  Finish the worksheets if you didn’t finish  Read Chapter 3 Sections 1 & 2  Scans will be posted online
