Hi Dylan, same comment from the previous post: 

1) What you stated as a hypothesis, actually, is a prediction. In the hypothesis, you state which variable will be affected by which factor. Then, you predict what you are expecting to see. For example: 

Hypothesis: We hypothesized that the water temperature will affect the cellular respiration rate. 

Prediction: Specifically, we predict that the rate of cellular respiration for the plant into boiled water will increase and turn the phenol red to a yellow color.

2) Replicants are an important detail for the experiment, they will help you validate your data and run the statistical analysis later.

So, do 3 replicants for each solution. Do you have material for that? 

Hi Christian! Good job! Just a few things to improve: 
 

1) What you stated as a hypothesis, actually, is a prediction. In the hypothesis, you state which variable will be affected by which factor. Then, you predict what you are expecting to see. For example: 

Question: Can pH levels affect the rate of photosynthesis? 

Hypothesis: We hypothesized that photosynthesis rates are affected by pH levels.

Prediction: Specifically, we predict that if leaf disks are placed in a solution with a low pH level, then it will take longer for the plant to conduct photosynthesis.

Hi Christian, 

Yes, the color does affect the photosynthesis rate. Green Light is not good for photosynthesis because this light is not absorbed. This happens because the chloroplasts are green, thus the green light is reflected.

If we are talking about regular bulbs, the sunlight is more effective because the sun emits a continuous wavelength with more of the beneficial wavelengths for photosynthesis. I'm gonna post a graph about it next, so you can check it.
