This unit was planned as part of the Chemistry IB Option B - Biochemistry scheme of work, and covers all the topics at SL and HL. It would also be suitable for other schemes of work.

It includes 10 full PowerPoints, along with student versions to use as notes, which have spaces for the students to add in missing information and activities for them to complete.

It also includes exam questions for practice or assessment purposes

Personally i found them to be quite poor for 15pounds. I normally don't buy resources so i expected a lot for the price they were. I spent the same amount of time planning my lesson as before. Not worth it
