Although today's lesson was cut short, we learned that...
Matter could be divided into:
- homogeneous- consists of only ONE visible component
- heterogeneous- consists of MORE than one visible component
We also learned...
The differences between an element and compund is that:
- Elements cannot be broken down into simpler substances by chemical reactions
- Compunds are made up of two or more elementsby chemical reactions.
Finally, we learned...

- One method> Electrolysis(process which splits the substance into its constituent elements)
