What is the definition of matter?
Anything that has mass and takes up space.
An educated guess
Hypothesis
What property of matter do cobalt, nickel, iron, and steel have in common that other metals do not?
Magnetism
I am clear, I am more dense than water, I am not soluble, I do not conduct electricity, I am a conductor of heat. What am I?
Glass
Solid liquid gas
Name one object that is matter.
anything
In science we always used what types of measurements? These are used all over the world except the US.
Metric
I am less dense than water, I am not soluble, I am a liquid. What am I?
oil
Explain the difference between mass and weight.
Mass is a measurement of the amount of atoms that make up an object. Mass does not change when you go from earth to the moon. Weight is a measurement of the pull of gravity on an object. Weight will change when you go from the earth to the moon.
Six properties of matter studied in class and explain each one.
Solubility, states of matter, conductor of heat and electricity, magnetism, density
True or False: Air is not matter because we can not see it.
False: Air is matter because it is made up of atoms that have a mass and take up space.
List the three states of mater
liquid, solid , gas
I am less dense than water, I am a solid, I do not conduct electricity, I do not conduct heat, I was once alive. What am I.
wood
A am abiotic(nonliving), I am almost always less dense than water, I am a solid, I am an insulator of heat and electricity, I am flexible, I am easily recycled. What am I?
Plastic
I am a solid, I am more dense than water, I am a conductor of heat and electricity, I am a alloy, I am attracted to a magnetic.
Steel
True or False: Air can be compressed.
True
Name three reasons why we would need to use a model to help us understand something instead of the real thing?
