P9 Electromagnetic Spectrum (Combined Science)

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):

P9 electromagnetic spectrum from davaruss

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.

8.3 Photosynthesis

BioKnowledgy 8.3 Photosynthesis AHL from Chris Paine.

Find a video lesson on this sub-topic at Dan Rott videos.

8.2 Photosynthesis essay qus

Paul Andersen explains the process of Photosynthesis in a 12m 27s tutorial:

Also IB 2.9 & 8.3 – Photosynthesis Part 1: Introduction to photosynthesis including ways to measure the rate and limiting factors of photosynthesis in 10m from Dan Rott. Or here is Photosynthesis part 1 of a series of tutorials, specific to IB Biology from Alex Lee.

Click on ‘Photosynthesis’ to see a detailed Interactive Animation from Wiley that covers all the reactions of Photosynthesis.

LIGHT DEPENDENT REACTIONS

Two fantastic animated tutorials from McGraw Hill Education – photosynthesis electron transport and  photophosporylation (cyclic & non-cyclic) – both are a bit more detailed than we need but they’re good.

This animation also shows how PSII and PSI reduce NADP: here.

This short, simple animation is a good summary of photosynthetic electron transport. as is this one from Biology 231.

Photosynthesis – Light-dependent Stage, an 8m video from Mr Exham or here is IB 2.9 & 8.3 – Photosynthesis Part 2: LDR in 9m from Dan Rott.

Mr W sings Photosynthesis – the LDR.

LIGHT INDEPENDENT REACTIONS (CALVIN CYCLE)

The Calvin cycle – a fantastic animated tutorial from McGraw Hill Education.

And here’s an animated, narrated tutorial on harvesting light – PSI & PSII in photosynthesisfrom Sinauer Associates.

Photosynthesis – Light-independent stage, a 5m video from Mr Exham, and here is a 5m TED-Ed lesson: Nature’s smallest factory: The Calvin cycle and this is IB 2.9 & 8.3 Photosynthesis Part 3: LIR in 11m from Dan Rott.

Mr W sings Photosynthesis – the LIR.

CALVIN’S EXPERIMENT

BioNInja has a great summary of the lollipop experiment, including a nice animation.

The Calvin Experiments – an animation that takes you through the 3 techniques he used to investigate the LIR.
