Unit 19 Spectroscopy - Introduction and Infa-red spectroscopy

I created this lesson for the new unit 19 level 3 applied science, assignment B, spectroscopy. This lesson lasts about 1.5 hours including completion of activities and introduces the students to spectroscopy by recapping the electromagnetic spectrum (I have also included some points in the notes section of the powerpoint which you may wish to discuss).
The data sheet I used with my students was the OCR A A Level Chemistry one (just what was handy in the lab) and the PowerPoint refers to worksheet A which is part of their assignment. This can be found on the Pearson website, along with answers.

I have included a link to a video I created introducing IR spectroscopy, aimed at students :) https://www.youtube.com/watch?v=XxYTIuKYbvc
