Elements, Compounds, and Mixtures

The next two weeks we will spend time learning about the differences between an element, a compound, and a mixture.  The basic definition of an element is that it is the small unit of something that still retains the characteristics of what it is.  It is made of only one kind of atom.  The basic definition of a compound is that it contains two or more atoms of different elements that are BONDED together and can be broken down into smaller elements.  The basic definition of a mixture is that it contains two or more elements that are mixed together but are not bonded together.  You can physically pull apart the two types.  That is it in a nutshell, but of course there are more details to be learned about them.  Expect quite a few powerpoints to help explain the concepts.
Additionally, we are going to learn about methods of separating and purifying substances, including why it is important to purify a substance for everyday life.  Exciting!!!!
I think we can expect the quiz on Feb 9/10 so we can do the s'mores lab on Valentine's.  Who does not want chocolate on Valentine's day!  Keep checking the blog for updates and links to useful websites.
