By: Emily B. Grade 9
Matter Matter is anything
that has volume or mass
Volume- Something that takes up space
Mass- The amount of
matter in an object *Both show volume.*Books take up space on the shelf*Earth takes up space in the universe. *Also show mass* Not all planets weight the same even they are the same size*Same for book, same size different weight
Non- Matter Things that do not have
volume or mass
~ Volume:
Anything that takes up space
~Mass:
The amount of matter in an object
Sound\music Do not take up spaceCan not find mass
Pure substance• Matter that consist
of only one type of particle
Both have only one type of particle Copper: Cu
Element• A pure substance
that can not change into anything simpler
~Contains only one kind of particle
Gold: Au
Compounds
• Pure substance that consist of to or more elements
Salt is made up of sodium chloride, sodium
Silicoaluminate and More
Mixtures
• Contains more than two or more pure substances
~ Ex. Salt added to water
Both have mixtures of more than one elementComputer is made of
Many things like Plastic, light which areMade of many things
Stain Glass is made of Class and colouring which
Is also made of many elements
Heterogeneous Mixtures
• A mixture that is unchangeable in its substance
This salad sauce is made of oil,Slat, pepper, and more things
As you can see, when the sauce isNot shaken to mix everything
Together, then all the ingredientsseparate.
Homogeneous Mixtures
• Substances that are equally and
microscopically mixed together
~ Soda pop= Sugar, corn syrup, carbon dioxide, water
When tea is mixed with water, the waters taste changes into the tea's flavor
Mass
• How much matter is in an object which does not change like weight
Both glasses ofWater are the sameBut as you can see
from the scale The glass cup weighs
More then the Plastic cup
Volume
• Amount of space an object takes up
The necklace takes upSpace in the box and theBlue air bubbles in the Glass take some of the
Objects space
Density
• The mass per unit volume of a substance
~ Can be measured by: Density= mass over volume
The ice cubes in the glass of waterare all floating on top of the
Water which means that the iceCubes have less density then the
water
Viscosity
• The state of being viscous
~the property of a fluid that resists the force tending to cause the fluid to flow
This kind of Nutella is viscous,When put upside down, the chocolate
Does not fall off like liquid wouldIt simply sticks onto the knife
State
• Matters that can normally be found in are, Solid, Liquid, and Gas
The top picture (Gas) is theEvaporation or the water in
My mouth, The bottom picture(liquid) is just water spread On water. An example of
Solid would be an ice cube
Conductivity
• The ability of a material to conduct electricity or heat
The pencil in this pictureAllows the current to flow From one end of the pencilTo the other to then go into
The light bulb, another Example would be, metal.
Physical Change• The substance
remains the same before and after the change, it may cause the form to change but not the substance The paper did get riped
But the substances in it Are still the same The cube did melt but the water
Inside it is still the same. ToMake a cube you freeze waterAnd when it is frozen it is stillThe same water, same here
Chemical Change
• When a substance changes into one or more new substances with different properties.
~Ex. Burning candle into energy\heat
Rice and uncookedRice, the chemicalChanges since the
Rice is now soft and Ready to eat whileIt was not before

If you have any questions please ask one of the grade 9 student.
