The graph should show an increase in arbitrary units the further away from the light source the beaker is because the greater the distance from the light source‚ the lower the light intensity and so less photosynthesis

Conclusion: The hypothesis was correct as the heart beat did increase as the caffeine concentration increased. However‚ this experiment could have been more fair due to the following: * All the daphnia used

Experiment 4A – Counting Atoms in a Chemical Reaction Purpose: The purpose of this lab is to create an experiment where zinc reacts with hydrochloric acid in order to find out the number of moles and atoms of zinc reacted. This can be accomplished by weighing the sample before and after the reaction with hydrochloric acid. Data: Material Mass in grams (g) Initial mass of dry beaker 49.37 Initial mass of dry beaker + zinc 51.03 Initial mass of zinc 1.66 Final mass

Experiment 9 Thin Layer Chromatography Experiment: 9 Title: Thin Layer Chromatography Introduction: Chemical analysis is conducted on specific analytes (specific substance of interest in a mixture)‚ however it is often found that these analytes must be separated for the chemical analysis to conduct their analysis. Chromatography is a set up of laboratory a technique that is used to separate a chemical mixture. This technique is very useful as it allows us to follow the course of

Experiments: Doctors‚ Experiments‚ and Results Melissa Anjeanette Edwards POLYTECH High School of Kent County‚ Woodside‚ Delaware Abstract During World War II experiments were done on the prisoners of war in Nazi Germany. Doctors for these camps came in all shapes and sizes including former S.S. Troops‚ Women‚ and a variety of prisoner doctors. The experiments differed as much as the doctors themselves; however they stayed the same in one factor‚ medical curiosity become killing in atrocious

Throughout the experiments the size of the balloons stayed about the same size except for in experiment 3. Also the bottles that had more sugar had a stronger scent of alcohol and also contained more foam on top of the liquid. All yeast in each of the bottles seemed to have fermented at the same time and stopped/slowed down‚ the growing process‚ at the same time. Bottle 3 also would always overflow and the foam would fill the ballon in every experiment. Another trend with bottle 3 was that in the
