I think that the plastic floating in the water is an interesting topic because it does not really have any answer. It is about the plastic in the water. Marine life might be getting stuck in it. Scientists have fished and counted how much plastic they got. The weird thing is that the amount of plastic has stayed just about the same even though now we throw away more trash. The scientists think that it might be breaking apart so we cannot see it, or they could have been eaten by marine life, or it could have just sunk. Although nobody really knows why, the amount of plastic has stayed the same and does not go up.


I think that it is very interesting that the amount of plastic has just about stayed the same. One of the questions I had was, will the amount of plastic always stay about the same? Another one of my questions is, are there any more reasons why the amount of plastic has stayed the same?

Matter

States Of Matter	Volume	Mass	Shape	Compress	Heating	Examples
Gas	Indefinite	Definite	Indefinite	Easily compressible	Expands greatly	Helium, Oxygen,  Hydrogen
Liquid	Definite	Definite	Indefinite	Low compressibility	Expands Slightly	Water,  juice, soda
Solid	Definite	Definite	Definite	Almost none compressibility	Expands low	Chair, desk, pencil

All states of matter have a definite mass. All states of matter except gas have a definite volume. All states of matter have a different amount of compressibility.   

What I have learned about matter

I have learned that everything is matter except the vacuum in space.  Another thing I have learned is that suspension is when you add either a solid with a liquid or a liquid with a liquid and they don't separate right away. Something else I learned is that saturated is when you can not add anything else to the mixture without it separating.

What I know about matter and elements

Matter is everything around us. It is liquid, solid, and gas. For example, water, ice, and vapor. The elements are in the periodic table. For example, H (hydrogen) O (oxygen). They can be put together to form to form compounds, as in H2O (water). 

Abby's science goals

      My science goals are to, get more organized, get all sevens, and to not get to class late. I think it is important to get organized because you will fall behind in homework. It is also important to get all sevens because it will feel good and you would have more confidence. It is important to not be late to class late because you will just start to fall behind in work.
