Investigation into the effect of Light Intensity on Photosynthesis in Elodea

Prediction

I predict that as the light intensity doubles the number of bubbles produced per minute will double

Results

Conclusion

Figure 1 shows that repeat 1 rises steadily then when light intensity is at 0.4, 1, 1.2 it rises rapidly then will slowly level off as you cannot acquire anymore bubbles from the Elodea. Figure 1 likewise also shows that Repeat 2 rises slowly then goes down rapidly than it rises rapidly again and levels off. Figure 1 also shows those repeat 3 rises slowly and levels off.

When the Light Intensity rises and the distance from the beaker moves closer to the light the Elodea produces more bubbles of carbon dioxide rises until there is no more carbon dioxide in the water or in the Elodea so that is why the results in figure 1 levels off.

The results show that my initial idea was correct as the distance from the beaker is moved towards the light the results of repeat 1,2 and 3 proceed higher. Repeat 3 has a increased gradual results than repeat 1 and repeat 2 who are other 100 by distance from beaker ...
