The Law of Sources

I have created and linked below a handy Law of Sources document. Learn this (if you don't know it already) off by heart for the exam on Tuesday. I was very encouraged by your responses today, you have all learnt a lot.

I have also tried to make it even easier to remember each of them with a picture to represent each law. Can you match each picture to a type of source question? (Check the document for the correct answers)
