Photosynthesis Rate and Light Intensity¶
Use this interactive to practise the usual pondweed lamp-distance practical: move the lamp, measure how many bubbles the Elodea gives off, and compare the results against lamp distance or a simple relative light-intensity scale.
What This Simulation Does Not Show¶
- Bubble count is only an estimate of oxygen production because bubble sizes can vary between runs.
- The light-intensity values are relative values worked out from lamp distance, not direct light-meter readings.
- A real practical would also control temperature, carbon dioxide supply and the size of the Elodea piece.
