I decided if something was matter or not, depending on if the object had mass, and if the object took up space. Such as oxygen, oxygen has molecules in it that still weighs something even if it is very very light. Plus, molecules also take up space because they are solid.

I really didn't Have a rule i just thought which ever one i thought had matter i would mark it

# data[].attributes.body
My rule for if it was matter or not, was if I could see it, feel it, or know it was there.

For me to decide if something is matter or not I have to think about what it is and if it fits into one of the categories of states of matter either from solids living or not , to gasses. Also I don't have to see them but they have to be there.

I think living, tangible, and intangible is matter. Everything in the universe is made up of atoms, or has yet to be proven otherwise, and I believe that atoms are made of matter therefore making everything else made of matter.

If you can touch it is matter.

The rules is anything that exists has matter

mine was it has to be a solid.

If it takes space it is matter

My rule is that if it takes up space (whether you can see it or not) it is a form of matter.

My rule is that is has to be made of particles or liquids and gases

The rule I used was to check if each item fit into each type of matter. For example, I knew that love didn’t fit into any of the three categories. But when I got to rock however, I knew that a rock fits into the  solid category.

My rule is that if what you are observing is a solid liquid or gas, it has matter. - Allison

# data[].attributes.body
My rule is

# data[].attributes.body
my rule was that if you can sense it there, and if it has a determined shape or demeanour, then it may as well be matter. if it does not, such as air or sound waves, then it is not matter. fire is living, but also not. it does not think, but merely devours most in its way, but it exists. water is living. it does not think, but it knows when to respond to the moon and when to rise up. the waves are water breathing, in a way.

It should either be solid or be proven by scientific evidence

My rule is to pick the living and non living matter

My rule is if it was solid, liquid, or gas it was made of matter.

My rule is that just because you cannot see it doesn't mean that it is not matter. If it is alive a liquid, solid, or a gas it is matter.

Matter needs to take up space not like sound waves. Air is made of matter even though it seems like its not but it fills up your lungs if you try and breathe in for long you can't for too long because your lungs are filled.

# data[].attributes.body
I said that mater is a solid, liquid,and gas.

My rule finding out on if the thing is matter or not is I think if I am able to write it. This means I have to be able to touch it to make sure that it's matter.

# data[].attributes.body
My rule is. If you can touch it or feel it with your body, it is matter.
