Effect of Sugar on Bean Plant Growth

Procedure: I used a ruler, thermometer, and scale to take measurements. I used a graduated cylinder, short step pipet, scale, and ruler to determine volume and density. I used a volumetric flask, graduated pipet, pipet bulb, scale, and glass beaker to determine concentrations and densities of various dilutions.

3% hydrogen peroxide, a household blender, potatoes (3 medium size potatoes, that are peeled and quartered), tap water, 8 test tubes, 8 transfer pipets, sugar packets, salt, a small saucepan, a refrigerator with a freezer, stove, 4 clear plastic cups, tongs (to remove test tubes from boiling water), 4 coffee cups, cheesecloth to filter the potato extract, a wax pencil or Sharpie marker, a ruler, scale or balance, 250 ml graduated cylinder, and oven mitt or tongs.

The first lab was conducted to analyze how germination affects the rate of cellular respiration in lima beans compared to dormant seeds. In order to

The lab leaders and the Punk Rock Warlord prepared three different concentrations of catechol oxidase by extracting potato juice (because it contains lots of catechol oxidase). Pure catechol, a 5mL test tube, 1mL/5mL

First, before starting my experiment I did some research on the growth of lima beans, so that I could start the base of the project. According to research done at the University of

In a third test tube, put 1 mL of chutney. Repeat steps 2 and 3 with the chutney and record the results in Table 3.

The purpose of this lab was to investigate and observe the effects of organic vs. synthetic fertilizers on plant growth by planting lima beans with added amounts of fertilizers, and to see how does adding different nutrients to the soil affect the growth of the lima bean? A significant difference was examined between the plants that contained manure and miracle growth, unfortunately the plant with no additional fertilizers (Plant #3) did not show any growth. The plant that grew the most was the one that contained manure, to an extent the one that grew the most in a short period of time was the one that contained miracle growth, as shown in figure I. The hypothesis explaining if the Lima Bean plant contains synthetic nutrients in the soil then

While experimenting with the green beans, the seeds exposed to the organic plant food germinated within five days of the experiment and the seeds exposed to the chemical plant food germinated within six. The seeds that acted as the control had been expected to grow the least, however, it was surprising that they did not grow at all. Both the chemical and organic fertilizers proved to have positive results on the plants. It was also unexpected when the seeds exposed to the chemical plant food surpassed the height of the other experimental seeds after being shorter. The predicted reason for the increase in growth with seeds given Miracle Grow was because chemical fertilizers automatically store up the nutrients and disperse it constantly throughout

Using the line of best fit equation from the yellow 5 and yellow 6 food dye, it was determined that 6.07 mL of yellow 5, 3.17 mL of yellow 6, and 0.93 mL of distilled water were needed to make our artificial food dye to mimic the orange PowerAde.

Out of all the nutrients tested, the pinto beans that grew with liquid fish fertilizer showed the highest growth rate, growing up to 12.5 inches tall. The plant growing with liquid kelp fertilizer grew up to 10 inches tall, and the plant growing with only water grew 9 inches tall. The pinto beans grown with fertilizer grew faster and taller compared to the one grown without any fertilizer. They grew two to three inches taller than the pinto

The Red #40 was mixed with 10 mL of DI water, the solvent. The volume of stock solution needed to prepare these solutions are shown in the second column of Table 3. After obtaining the appropriate micropipettor, 200 uL, it was used to measure the aliquot of the stock solution. This solution was transferred into a volumetric flask and diluted with the 10 mL of DI water. DI water was used as the blank and the solutions were then placed inside the cuvettes which were then placed into the Vernier pH spec-trophotometer. The absorbance and λmax of each solution were then recorded as seen in the third column of Table 2. These values were then plotted on a linear regression as seen in Figure 1. Next, 0.50 mL of maraschino cherry juice was obtained by using the appropriate micropipet-tor, 100 uL, of the aliquot of the stock solution. This was transferred into a volumetric flask and diluted with nanopure water until the solution reached 25 mL. Nanopure water was used as the blank and the solution was then placed in a cuvette which was then measured inside the Vernier pH spectrophotometer. The absorbance and λmax of this solution was then recorded in third column of Table 3. The cherry juice and nanopure water solution was calculated by using the linear regression equation seen in Figure 1. The cherry juice concentration and nanopure was 2.26 uM. The stock solution was calculated by using m1v1=m2v2. The cherry juice concentra-tion and nanopure water mass, uM, was m1 and the 25 mL of the diluted solution was v1. The v2 was the 0.50 mL of the cherry juice. After calculations, the m2 was calculated. It ended up being 131 µM which was the mass of the stock

During the 18th and 19th centuries, at the time where ships would transporting goods and the navy would patrol the area, many of which are called “Limeys”. Although, the Navy Sailors often fell down with a symptom called scurvy that would cause their gums to bleed, fatigue, rashes, muscle weakness, and depression. In order to counteract this testament, these sailors would put lime into their rum (alcohol) to keep themselves healthy throughout their long voyage(Source A and B). Now, what makes vitamin c so important that it should be used in diets? Maintaining a lead to a prevention of many types of illness and can be easily found in vegetables and fruits that contain citric such as broccoli, spinach, sweet potatoes, watermelon, lime, etc (Source

In this experiment I will be finding out which fruit juice contains the most vitamin C. I will be using a method similar to titration but I will be using a syringe instead of a burette.

After I collected the data the how much Iodine reacted, I averaged my measurements and used those value in calculations. This approach helped me to minimize the different errors of measurement. The concentrations of Ascorbic Acid could be calculated by referring to the values of Iodine solution as a standard. Finally, I found that Cran-apple juice has the highest concentration of Vitamin C, Green Tea has the second highest, then Rose Hips, and orange has the least concentration of Vitamin C. These results are shown in the graphs. However, the results did not support my

Orange Juice Materials: Three oranges were used for this experiment to obtain a decent amount of juice. Each orange was cut in half and juiced according to steps 1 and 2 of Appendix I of the Laboratory Manual for Biology 201 (Denniston, Wimmers, & Hemm 2015). The juice from the first orange and one half of the second orange was strained into a small beaker following
