"Because Matter matters" -(Teacher)

I was very Optimistic because of my class of chemistry on Tuesday, when I arrived to the math classroom in the morning a friend of mine and me realized an interesting question on the board (because of a chemistry class before my math class in the same room), it said "What is matter?" Immediately my friend said "Everything that has mass and occupies space" and I just tought ...WOW now I remember that.
After the repetition of that definition on my mind all day, the chemistry class finally arrived and what the teacher assigned was to make a conceptual map about...Guess What?... MATTER!! But the issue was that I had no Book and my only source to the internet was my iPod, what a problem, I had a hard time trying to remember some things, but I was pretty sure about the matter (:D) that matter has 3 states, solid, liquid and gas, but I needed information about physical and chemical changes and properties. But later I just chatted with my mates and got to the point that physical changes are the ones that doesn´t change matter´s nature, they just change its outer form...and chemical changes are the ones that transform the nature of matter... A great introduction for a hopefuly GREAT semester at Chem class! :)
I loved to remember that ...
It´s great to get back on the business of Chem!!!
