How Does Light Affect The Rate Of Photosynthesis?


Problem: ?
The Plan
In my experiment I am going to see how light affects the rate of photosynthesis. To do this experiment I am going to set up the apparatus as shown in figure 1.
The apparatus I am going to use are the following: -

1 Tripod
1 300ml Beaker
1 Boiling Tube
1 Clamp Stand
1Clamp
1 Boss
1 Ring Binder
1 Lamp
1 1 Metre Ruler
1 Thermometer
1 Stop Clock

To do the experiment I will set up the apparatus first. I will firstly place the tripod on top of the base of the clamp stand and fill the 300ml beaker with 250ml of water to create the water bath. I will place the boss in the middle of the bar on the clamp stand and place the clamp in the boss. I would then fill the boiling ...

what problems we might face when we did the main experiment and gave us the idea how to do it.

The pondweed should create photosynthesis by the following equation: -

6CO2 + 6H2O 6C6H12O6+ 6O2

Photosynthesis occurs when plants take in Carbon Dioxide from the surrounding air in its leaves and water from the nearby soil in its roots. The leaves then take light energy from the Sun, which is absorbed in the chlorophyll in the cells and passes it along for it to be used in photosynthesis. Glucose is produced and is converted into Starch to be stored. Oxygen is produced from the water and it is a waste product so it is released into the air. The plant uses Carbon Dioxide and water to create Carbohydrates. Glucose is a small, soluble molecule which is useless for a plant to use as energy but it converts it into Starch, which is a large and insoluble molecule, so it can be stored for to be converted back into Glucose.

I made this experiment as fair as possible. Firstly, I put ...

preliminary attempt. The results are inaccurate because it wasn’t a fair test, as I didn’t use any safeguards. 22 has a star next to it because it is an anomaly. This is due to the fact that no safeguards were used and possibly the pondweed caught ‘foreign’ light.

Attempts

20cm 68 *65* 68
30cm 34 31 32.5
40cm 18 15 16.5
50cm 10 9 9.5


These are the first set of results done with fair testing. The anomaly in these results is 65 because not all of the Sodium Bicarbonate was mixed in the boiling tube with the water.
