Effects Of Hydrogen Peroxide On Seed

Mackenzie Warfield Bio Lab 100 Section 2 Experiment Rough Draft
Does Hydrogen Peroxide Help or Harm Seeds? Hydrogen peroxide (H2O2) is a common household item. It is made of two hydrogen atoms and two oxygen atoms. It is most commonly used in small concentrations to clean small cuts and scrapes by killing bacteria. This antiseptic kills the bacteria by tearing down their cell walls. In the last few years, hydrogen peroxide has been added to pesticides. This means that the food we consume has been growing in materials that contain hydrogen peroxide. We have a right to know what our food has been produced in and what we are ingesting. This experiment benefits the world of agriculture by showing what soil and chemicals our food should and should not be grown in. The objective of our experiment was to determine and observe if hydrogen peroxide has any effect on crop seed germination: germination time and number of germinated seeds. We did this by watering our seeds different concentrations of hydrogen peroxide. My partner and I tested on three different types of seeds; corn, bean, and pea. I hypothesized that the higher the concentration of hydrogen peroxide added, the higher percentage of seeds will grow in that solution. I also believed that higher concentrations of hydrogen peroxide would quicken seed germination among seed types. My …show more content…
The dependent variable was the time of seed germination and the independent variables were the hydrogen peroxide concentration and type of seed used. There was one control for each seed type, all with 0% hydrogen peroxide concentration. We first created the water and hydrogen peroxide solutions: no hydrogen peroxide (0%), low hydrogen peroxide (2%), mild hydrogen peroxide (5.5%), and high hydrogen peroxide (10.7%). To create those solutions, we added 0ml H2O2, 5ml H2O2, 15ml H2O2, and
