Lima Bean Gatorade Lab Report

4. EVALUATION AND CONCLUSION CONCLUSION The data did support my hypothesis as stating that the larger a cell is, the harder it is for diffusion to take place as the surface area to volume ratio decreases throughout evidence supported. There is a pattern in table 5 shows that, the surface area to volume ratio decreases when the agar jelly increases in size from 1cm to 3cm cube by a ratio of 6 to a ratio of 2, showing that average rate of diffusion which decreases as the size of the agar increases has a linkage to cells as cells increase in sizes.

The purpose of this experiment was to test multiple brands of popcorn under the same setting in order to conclude which one statistically popped the most kernels. I tested the butter flavor of Orville Redenbacher, Wal-mart’s Great Value brand, and Pop Weavers. The different bags of popcorn were popped in the same microwave for the same amount of time, 3 minutes and 15 seconds. Then, the popped corn was counted, as well as the un-popped kernels, in order to determine a ratio, and then I recorded the results in the data table. I repeated these steps two more times for a total of 3 trails for each brand. Then I compared the ratios of all the bags to determine which brand yielded the most popped corn. The statistical technique used to evaluate the data was to find a ratio between the number of kernels in the bottom of the bowl and the number of popped kernels. To find this, I divided the number of the actual popped corns by the total number of kernels left in the bottom of the bowl. The ratios and percent were then compared. Once all my results were in the data table, I averaged the 3 trials for each brand of popcorn.

Human error is easily obtained when working on an experiment with so many different solutions, time measurements, and accuracies of measurements. An easy mistake could have been made while waiting 15-20 minutes for the Carb Cutter to digest. With the time crunch in the Biology Lab, the Carb Cutter may not have been completely digested before rushing to begin the experiment. The results from the experiment showed an increase in absorbance with the Carb Cutter pill, which is not accurate because there is no way that more starch was made in the solution. Given more time for the procedure, this lab experiment may have received more accurate results.

I have always been interested in science, but the hands on experiments have helped me understand and grasp concepts much easier. I recall my first experiment in first grade when the class was given the lima bean sprout experiment, which required students to plant a bean in a paper cup. The purpose of this experiment was to teach us about photosynthesis and practice our observation skills. I recall how others were fascinated about why their sprout grew. I, on the other hand, was more captivated by why the other sprouts did not grow and the factors, which contributed to that outcome. This basic experiment taught me to look at things through different lenses and not always to the most obvious path.

The research question for the Alka Seltzer Lab is, “What is the effect of different surface areas of an Alka Seltzer tablets reaction time?’. Inside of an Alka Seltzer tablet there are two key ingredients; which are citric acid and baking soda. When a tablet is dropped into a liquid, the acid and baking soda show a physical reaction of fizzing and eventually dissolving. Materials needed for this lab was goggles, aprons, beakers, water of the same temperature, mortar pestle, and three alka seltzer tablets. In each beaker there was 150 mL of water. The first tablet was a full tablet, the second was broken into quarters, and the last tablet was crushed in a mortar pestle. The dependent variable of the lab was the rate of reaction, and the independent

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

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

My investigative question is does microwaved water stunt plant growth? I was interested in learning more about this topic because I wanted to know if microwaves can put chemicals in your food causing you to not get all of the nutrients from the food. The purpose of my experiment is to see if water set to a boil on the stove, water set to a boil in the microwave, or water from both the microwave and stove will make plants grow more, also to see if the microwave puts bad chemicals into your food. My independent variable is the type of water used. My dependant variable is the height of the plant. My hypothesis is, if plants are grown with microwaved water then they will not grow as much as plants grown with water heated from the stove.

In first half of the experiment, we tested 5 different compounds which one could work as an inhibitor. When using a 5-ml pipette with a green pump, we placed 5 ml of distilled water in each small labeled test tube. After that, we went to place 8 drops of potato extract, 8 drops of catechol, drops of an inhibitor, and then drops of distilled water. The only concentration that we had alternated in the experiment would be the drops of catechol and drops of distilled water. In tube 1, we placed 8 drops of catechol with 8 drops of distilled water in the tube, containing NO potato extract. In tube 2, we placed 8 drops of catechol, NO distilled water, and 8 drops of potato extract. In tube 3, we placed NO drops of catechol, 8 drops of

The Purpose of this lab is to determine if predation or sexual selection have a greater effect on the population of guppies with a specific coloration. The lab will began with mostly bright guppies. Thus, if there are more predators than only the drabbest coloration guppies population would survive.

The purpose of the experiment was to find a solution which would prevent an apple from turning brown, and to figure out whether the pH of a solution has an effect on the browning of cut apples. My lab partners and I thought that if we dipped the apples in lemon juice then it would prevent the apples from browning compared to other solutions. Solution A had a pH of 4, solution B had a pH 3, solution C had pH of 4, Solution D had a pH of 4. All the solutions apples including the no solution apples had a browning scale of 0 at the 0 minute mark. After 24 hours of soaking solution A had an average browning of 3, solution had B had an average browning of 0, solution C had an average browning of 3, solutions D had an average of 1.7, and the no solution

My lab was based on one very important question, how can the weight of potatoes change if

The question chosen to do an experiment on is does caffeine affect the growth of green beans if ground caffeine tablets are added to the soil. I chose this question because I strongly dislike waiting a couple months for plants to grow from seeds, so I want to try to make them grow faster. This project is important to everyone. People with short summers could grow a garden if the experiment works.

There could have been several variables that could have affected the results of this lab. One would have been if the salt measurements were incorrect. If more or less salt was added than realized, this would have caused the results to be incorrect. Another variable could have been the size of the potatoes being measured incorrectly. If

Water is the most natural thing we have on earth. It sustains many organisms and those organisms depend on it almost daily. Plants are such organisms. For this study the focus is the growth of beans. Over the course of two weeks my team and I conducted research comparing the two types of waters that were selected and seeing if they had any significant differences in growing beans. The first week was inconclusive due to bean rot and negligence. Test two led to a more constant observation of growth and change of location. Results gathered from this experiment have shown a difference that different waters may have on the growth of plants. Beans that consumed certain water sources
