Cover work

I will be off until Thursday 2nd October. There are some topics that you need to look at and some questions to do (which can all be found on the student shared drive).
There are some links below to support. We will go through the key points when I return.

Please make notes on:
magnification, the difference between analogue and digital signals, how analogue signals can be converted into digital signals, polarisation. Please go through the checklist for chapter 1 in you booklet and produce revision notes for the chapter.

Ch1 160C Satellite images (comprehension questions)
Ch3 10E Making estimates about information (estimation questions)
Ch3 70S Sampling and hearing (short answer questions)

This is the cover work for the lessons. You should continue to set yourself homework tasks outside of the lesson time.
