This is important becuase it is a main part of the unit because it is an esnetial part of our school year science leasons. This is because we will need to know density, reactivity comboustibility to tell many things like chemical reactions pysical changes. This is all needed for this year and chemistry later in our school lifes.
This is currently under devlopment, this will be adheared to at a later date.
