A good, general overview of Photosynthesis (2m 47s):
In Crash Course Biology #8 – Photosynthesis, Hank explains, well, photosynthesis.
The simple story of photosynthesis and food from TED-Ed. Find a video lesson on this sub-topic at Dan Rott videos, or many assessment statements are covered by Stephanie Castle (with more being added all the time).
Photosynthesis and Respiration compared in a lovely interactive tutorial
PRACTICAL – Rate of Photosynthesis
Here are two from BiologyCorner: Photosynthesis Virtual Lab and Algal beads and Photosynthesis.
Dynamics of Photosynthesis – a lab simulation and from Gizmos – Photosynthesis Lab.
PRESCRIBED PRACTICAL 4 – Chromatography of plant pigments
Separation of photosynthetic pigments by chromatograph
One way to do it is this: chlorophyll chromatography and an alternative method includes how to calculate Rf values. Hopefully the final result will be this. An alternative method:
