If an object is more dense than water it will ______
Float or Sink
Sink
What are the 3 states of matter?

A material that allows electrical or thermal energy to easily more through it is called a __________
Conductor or Insulator
Conductor
What happens to a soluble substance when it is placed in water?
What tool would you use to measure how much mass an object has?
Triple beam balance
Balance
Digital Scale
If an object is less dense than water it will _________
Float or Sink
Float
Which physical state has a definite shape and definite volume?
Solid
A material that slows or prevents electrical or thermal energy to move through it is called an __________
Conductor or Insulator
Insulator
True or False
Sugar is soluble in water
True
Sugar dissolves in water and becomes uniform (you are unable to see both substances)
Object A has a mass of 45g
Object B has a mass of 72g
Which object contains more matter?
Object B
Is oil more or less dense than water?
Less dense
It sits on top of water which means it is less dense
When a solid heats up and turns into a liquid it is called _______
A.) melting
B.) condensing
C.) evaporating
A.) melting
Which would most likely be used to help conduct electricity from one place to another
A.) a rubber band
B.) a copper wire
B.) a copper wire
True or False

Which of these is a unit of measurement for Mass?
a.) cm
b.) mL
c.) g
c.) g Grams
Is honey more or less dense than water?
More dense
Honey sinks below the water so it is more dense
Which has a greater density, a liquid or a gas?
Liquid is more dense than gas
The particles in liquid are more tightly packed together
True or False
All metals are conductors
True
True or False
Salt is soluble in water
True
Salt dissolves in water and becomes uniform (you are unable to see both substances)
True or False
If an object is large it automatically has more mass than a smaller object
False
Size does not determine mass
An object has a density of 8.5 g/cm. Will it float or sink in water?
Sink
Water has a density of 1 g/cm
8.5 is MORE than 1 so it will SINK
In the morning you see a puddle on the ground. After a sunny day you notice that the puddle is no longer there? What happened to the water?
It heated and evaporated
True or false
All conductors are magnetic
False
Some metals that are conductors are not magnetic (like copper)
True or false
Green Food coloring is insoluble because you can still see the green after it is mixed into water
False
Food coloring is soluble in water
The color spreads out evenly (uniform) so you can't see BOTH water AND color. You can see only color.
You can no longer see both substances
