Mixture and Solutions
When two or more substances are combined and they do not create a new substace
Mixture
When an object if less dense than water it will....
float
Definition of Conductor
something that allows the flow of electricity
The three states of matter
solid, liquid, gas
This matter is a solid, is conductive, is more dense than water, is not soluble in water and is copper. What is the object?
penny
When two or more substances are combined and they create a new substance
solution
When an object is more dense than water it will.....
sink
Definition of insulator
something that slows down or does not allow the flow of electricity
This keeps is volume and shape
solid
This is soluble in water, creates solutions, is white, a solid, and does not create electricity.
salt or sugar
Cereal and milk, marbles and metal are examples of
mixtures
You have a mixture of oil, water, honey, and corn syrup.
The layers go, oil, water, honey, and then corn syrup on the bottom. Which is the most dense of the mixture?
Corn Syrup
4 examples of a conductor for electricity
copper, aluminum, iron, steel, metal
Changes shape but keeps its volume
liquid
This matter is less dense than water, the tip of it conducts electricity but the other part of it is a insulator, its does not dissolve in water, and unless melted it will create mixtures.
chocolate milk, salt water, sugar water are examples of what
solutions
Name three objects that would be less dense than water?
Pencil, ruler, ping pong ball, soccer ball, baseball, notebook.
4 examples insulators for electricity
plastic, wood, rubber, glass
Changes volume and shape
gas
This matter dissolves in water and creates solutions, is yellow and smells sweet, does not conduct electricity, is a solid until dissolved.
lemonade powder
Four ways to separate mixtures
magnate, sifter, tweezers, boiling water
What does it mean about the molecules in an object when it is more dense than water? (i.e. are there more or less)
more molecules in an object to make it more dense and sink.
When creating a cup to insulate the water to stay cool, what can you not have?
metal
What is not considered matter?
feelings, like love and hate
This matter creates mixtures and solutions, is a liquid, clear until new solution is created, does not have a true taste or smell, can be more or less dense depending on what is put in it.
Water
