Science Intensive with Miss Stone!

Today we have been learning about the three states of matter (solid, liquid and gas) and the changes of matter. In this experiment we first melted some chocolate in the microwave. This meant that the chocolate changed from a solid to a liquid. Then we piped it onto a piece of baking paper and further let it set. This meant that the chocolate changed back from a liquid to a solid.

A few days ago, I learnt about the three states of matter which are Solids, Liquid and Gases!, and what the particles (molecules) do, the definition of chemical changes, what are atoms/learning the Periodic Table and many more!

Liquid particles are together like a solid, but maneuvers around. (The bonds in the liquid is strong enough to keep the particles together, but also weak enough to let them flow together, kind of like a solid).
Solid particles are intact and stays together! (The molecules in a solid vibrates, but do not move past together like a gas. The solids retains its shape or mould).
Gas particles like to be separated! The molecules in gases move rapidly and past other molecules!

The definition of "Chemical Changes" is when a substance is combined with another substance to create a new type of substance. A chemical change is irrevocable, which has to include the rearrangement of either atoms or, 'as mentioned above' when two or more substances are mixed to create a new substance. An example of a chemical change is wood being burned, ever so slightly that ashes start to form and parts of the wood will turn color (pitch black) and eventually burn, that is a chemical change, it cannot been turned to it's original form unlike a "Physical Change", which in this case can be turned back.

Moving onto Atoms, What are Atoms, you might be dying to hear about?, well an atom is a “particle” that can only be seen using a machine (microscopic machine). An atom is also indivisible, which means, however many times you cut an object or thing etc, it cannot be divided! There is also 3 other things that are involved which are Protons, Neutrons and Electrons.
What is a proton? A proton is a particle apart of Atoms, that is positively charged.
What is a neutron? A Neutron is also another particle of atoms and in which are neutral.
What is an electron? A electron is like a proton, accepts that they are both attracted to each other, but an electron has no electrical charge.
