matter is a substance which is in everything that has mass like pencil, paper, phone, table ,etc . Matter is anything that takes space or has a weight.
Mass is something that takes up space.
atoms in a solid are really compact but in a liquid they are a little spreed out and in a gas they are even more space apart. they are the common 3 but there are 2 more thatare a little less common which some people that dont know about. But there are 181 different types of atoms. The fourth one is plazmer and the 5th one is called bose-Einstein condensta which was created man made in 1995 wich is instead of lots of little atoms there is one super atom. and it is that cold that it is colder than Antarctica on its coldest day. bose-Einstein condensta is -273.15 degrees. On the moon your weight get taken down 16 % to what it normally is. In the university there 99.99 percent of plazmer.Here is what a atom looks like close up.

here are a picture of the three main matters

here is a picture of the man made atom
which is called bose-Einstein condensta
and under it will be the materiel that they used to make the bose-Einstein condensta


lesson 2
Chemical/Physical Change
today we learnt about the different between chemical and physical change.
first we got to watch Mr G put a piece of paper on fire then he explained why it was a chemical change and there was a physical change like scrunching up a piece of paper. That is a physical change because you can make it bake into what is was before so it is the same form. Also the same when you ripe the paper because you can put it back together. But when you put it on fire it is a chemical reaction because you can not make it the same form as it was before and it will probably change the colour.
