PROBLEM

Will changing the temperature of the plant’s environment affect its rate of photosynthesis?

HYPOTHESIS

If the temperature of the plant’s environment is increased, then the rate of photosynthesis will also increase and result in a faster production of bubbles.

INDEPENDENT: temperature of water

DEPENDENT: rate of photosynthesis/production of bubbles

CONTROL: light intensity, amount of carbon dioxide, amount of water, color of light

DATA

Temperature	Bubble Production (1 min)
10	60
25	43
40	22

RESULTS/CONCLUSION

In conclusion, my hypothesis was proven incorrect because my data showed that the lower the temperature was, the faster the production of bubbles. This means that the rate of photosynthesis will be more efficient in an environment of low temperature. Whereas, in the case of high temperature, the bubble production has a significant decrease, showing that the rate of photosynthesis is not as effective in an environment of high temperature. Thus, we can see that changing the temperature low can increase the rate of photosynthesis whereas changing the temperature high can decrease the rate of photosynthesis.
