2. Matter Lesson One Matter: anything that takes up space
Physical Property:
anything you can observe about an object by using your senses
Your senses are see, smell, taste, feel
© Denise Ritter

3. What matter looks like:
Physical properties that you can
observe with your sight:
Dull
Shiny
Colors
Size
© Denise Ritter

4. Physical property that you
cannot see is:
Temperature (you infer something is hot of you see steam coming from it or it’s cold if you see it with ice or snow.)
© Denise Ritter

5. What matter feels like:
Physical properties that you can feel:
Scratchy (like wool sweaters)
Rough (sandpaper/bark on tree/ gravel)
Smooth (sand/mirror/book cover)
Soft (animal fur)
Sharp (animal’s claws)
* You can feel some things you can’t see – the push of the wind or whether something is hot or cold

6. What matter tastes and smells like:
sweet
Pleasant odors –
Food cooking/flowers
sour
Unpleasant odors-
salty
Skunk/barnyard smells
bitter
*Careful with tasting – some things can make you ill
– even just a small piece.

7. Other properties of matter:
Break – glass, twig
Bounce - balls
Stretch – rubber bands
Bend – putty, clay, gel
Magnets attract objects made of iron

8. Three State of Matter:
Solid – takes up specific amount of space and has definite shape [volume stays the same] ex. ice, rocks
Liquid – volume stays the same, but it can change its shape. Takes the shape of any container. ex. water, juice, milk
Gas – takes the shape of the container it’s in – doesn’t have definite shape or definite volume ex. air

9. Solids, Liquids and Gas Atoms Atoms: basic building blocks of matter

10. How particles are connected:
Solid:
hard because particles don’t move very much. Particles very close together.
Liquid:
Particles are more loosely arranged than a solid. Particles slide past each other.
Gas:
Particles are not connected to each other and are not close to each other. Particles move in straight line until something stops it. Then it bounces off in a straight line.

11. How matter changes states:
Adding heat or taking heat away causes matter to change states.
Condensation:
The outside warm air (humidity –moisture in air or water in a gaseous state) hits the cold surface of glass and the cold temperature turns the gaseous state of water back to a liquid state.

12. The process (adding more heat) in which a liquid becomes a gas.
Evaporation:
The process (adding more heat) in which a liquid becomes a gas.

13. Measuring matter: -Measuring Volume- Volume:
amount of space matter takes up
-Measuring Mass-
Mass:
amount of matter in an object
*You can’t see mass – ex. Ping pong ball and golf ball
**You can’t see most gases, but like all matter, gases have mass.

14. Tools for measuring mass and volume:
Infant measuring spoon
Vegetable scale
Postage scale
Graduate cylinder
Measuring cup
Bath scale

15. Adding Masses:
If you take an object and cut it into pieces – the mass of the object has not changed. --Mass of all the object pieces is = to the mass of the whole object --
© Denise Ritter

16. Comparing Mass and Volume:
Different objects can have the same volume but different masses -- think back to ping pong ball and the golf ball.

17. Mixtures
A mixture is a combination of two or more different substances
Mixtures can be combinations of solids, liquids, or gases Examples:
sand and gravel – mixture of solids
muddy water – mixture of solid and liquid
Smoke – mixture of solid and gas (air and smoke particles
Coca Cola – mixture of gas and liquid

18. Mixtures
Mixtures can be separated back to their individual substances through a variety of procedures.
magnet
strainer
sieve
hand
tweezer
© Denise Ritter

19. Mixtures Formed when two or more materials are combined
They can be separated
Some separate on their own – oil and water; oil is lighter and will rise to top
Sugar/water mixture can be separated by heating it up and the evaporation of water leaves sugar crystals behind.

20. Solutions
Some mixtures of certain substances such as with sugar in water form solutions. Solutions are formed when they mix equally throughout (top, middle and bottom)
Examples:
Brass - Solid
Gas-
Air
Soda - Liquid
