In 1.2 we learned all about matter and changes of state.  We learned that all matter is made of small particles and that they are spaced differently in different states ( solid, liquid, gas).  We also learned about the kinetic molecular theory.  The theory suggests that all particles are moving and that the more energy or temperature that the particles have the more they will move.  Another thing we learned is changes of state.  We learned the vocabulary for when a solid turns to liquid, a liquid turns to gas, a gas to a solid and so on.  Lastly, we learned about elements and compounds.  Elements are substances in their purest form and compound are elements mixed to together to form another substance.  An example of an element is hydrogen and an example of a compound would be water ( two hydrogen atoms and one oxygen atom).  Thanks for reading what I learned about in section 1.2!
