then immediately recorded and the procedure was the repeated three times each with whole and crushed Alka-Seltzer tablets. Then results from three fellow classmates’ experiments would be recorded and added to our own results. The hypothesis was that more surface area exposed and smaller volume would result in a faster chemical reaction of the material.

The Effect of Light Intensity The effect of different light wavelengths was tested in the following experiment. The rate of photosynthesis can be affected depending on the light treatment it receives. With the aid of DPIP acting as NADPH in photosynthesis‚ it was possible to observe the reaction as it took place. Samples were created with dark‚ 24 cm‚ 30 cm‚ and 49 cm light treatments. The absorbance was measured in five-minute intervals for each sample and recorded in an appropriate table
