Our kids did a prac "Measuring the rate of photosynthesis" with elodea, bicarb and counting the bubbles at different distances and different coloured cellophane..
It gave many inconsistent results.
Has anyone done this and could possibly post the results for "light intensity" and "light spectrum" ???
Would be greatly appreciated!!
cheers,
Katie

Re: Photosynthesis - measuring the rate.
We do this prac (but with a different plant - elodea is banned here) but I think it is more to prove that photosynthesis occurs rather than to calculate rates. Sorry I can't help :(

Re: Photosynthesis - measuring the rate.
A replacement plant for elodea is hydrilla. I can buy it from my local pet shop used in fish tanks.. It looks similar to elodea but I think the leaves are a bit smaller and more serrated.
