I think that I have hit the following success criteria laid out at the start of the powerpoint (be honest this is a checkpoint for you):

• Students will be able to describe the difference between an acid and a base.

• Students will be able to name at least one base and one acid

• Students will be able to describe what each theorist has said defines an acid and a base.

• Students will be able to name an acid, base and a neutral substance and where it sits on the scale.
