Science Bank 5 (Waves): part 1 – introduction to waves (to 4m 15s); part 2 – reflection (to 9m 30s); part 3 – refraction (to 14m 10s):
P7 waves from davaruss
A short (3m 48s) video clip on Types of Wave (Clipbank).
Curriculum Bites has two short revision videos– Waves (5m 57s) & Uses of Waves (5m 19s).
GCSE Bitesize foundation level – Waves (17m 22s) – the first part covers the characteristics of waves.
Science Bank 6 (Electromagnetic Spectrum): part 1 – the visible spectrum (to 4m 40s); part 2 – longer waves (to 9m 15s); part 3 – shorter waves (to 14m 15s):
Three short video clips from Clipbank: the Electromagnetic Spectrum, UV & X-rays & the passionate Jon Chase describes Electromagnetic Radiation in 4m 19s.
All the different forms of radiation in the Electromagnetic Spectrum are described here in a 24m 30s video (BBC KS4 Class Clips).
Other videos include How does a microwave work? from Naked Science Scrapbook (4m 35s), Waves & Communication from Jon Chase (4m 19s), Science in Focus – Electromagnetic Spectrum (19m 9s), & in GCSE Bitesize foundation level – Waves – the second part revises the electromagnetic spectrum.

8.2 Photosynthesis essay qus
Paul Andersen explains the process of Photosynthesis in a 12m 27s tutorial:
Or here is part 1 of a series of tutorials, specific to IB Biology.
A short, simple animation to show photosynthetic electron transport and here is an animated video that explains the LDR.
Click on ‘Photosynthesis’ to see an Interactive Animation from Wiley or here are some fantastic animated tutorials from McGraw Hill Education – Photophosporylation (cyclic & non-cyclic) – a bit more detailed than we need but its good, photosynthesis electron transport & ATP synthesis & the Calvin cycle.
Finally, here’s an animated, narrated tutorial on harvesting light – PSI & PSII in photosynthesis – from Sinauer Associates.
Mr W sings Photosynthesis – the LDR and the LIR.
