By carrying out a comparison of the properties of parts of the electromagnetic spectrum. I have researched new developments in science and can explain how their current or future applications might impact on modern life. Having selected scientific themes of topical interest, I can critically analyse the issues, and use relevant information to develop an informed argument. Edition 9Ib(8) The appearance of wave patterns observed by the oscilloscope can be linked to changes in the pitch, volume and tone of sounds from different sources. 8La (PB8 p161-163) 8Lb (PB8 p164-165) 9Jc (PB9 p122-123) Skills Sheets: SS38 – SS40 APP Additional Task A ‘Media articles’ APP Pack ‘Demoting Pluto’ (Task 24) APP Additional Task A ‘Media articles’ © Pearson Education Limited 2009
