Hi Grade 11!
We are going to continue Energetics for HL.
SL, you have a study hall. You need to be continuing to work on the Revision packet that was posted on the Google+ Community.
This is new for 11A and practise for 11B. First of all, watch these series of videos:
Now that you have that, there is also a booklet to go along with this. Read the booklet and try all the questions at the end of the booklet. The answers are included.
Once you have finished those, there are some past paper questions that you will find here. We will discuss the answers when I get back next lesson.
Have a good day!
