Radish Sample Lab

Beforehand, I believed that, if fertilizer speeds the growth of plants, then the 9 pellets of fertilizer were going to make the biggest plant the fastest. I thought this because it would have the most fertilizer and if fertilizer speeds up the growth of plants then 9 must speed it up the most. However, I was not completely right with my initial prediction. My personal data came to the conclusion that the 3 pellets made the plant grow the fastest but in the class data by the end the average data showed that 9 pellets showed the most growth. This experiment was set up as four different plant seeds in four different quadrants. Each of the four quadrants had a different amount of fertilizer. We watered them and planted them in soil then every week we checked in on our plants. We measured the size if the plants and then recorded it and put them back under the fluorescent light. Then everyone recorded their data and we watched the class data on average, then the last day we measured the mass of the plants and found the class data. So although my prediction of 9 pellets of fertilizer creating the most growth was true in the class data, it was not true in my individual

Have you ever really wondered how different variables can affect how plants go through photosynthesis? Well, in this experiment, the purpose was to see how various environmental conditions can affect the overall photosynthetic capacity of a specific plant. The factors, light, darkness, cold, and heat were applied to see how the different components would affect the photosynthesis on spinach plants. Each group was given a different factor to test. Out group was given the light factor. The hypothesis for this experiment is that when adding light as a factor, the light will affect the overall plant photosynthesis.

In the dishes, I dropped the appropriate treatment into the center, where the marks were made. Next, I closed the petri dishes, taped them up, and let them sit at room temperature for a week. Then I opened them up to take two measurements. The first measurement was the number of seeds germinated. The second measurement was to measure the seedling lengths.

The experiment was begun by obtaining four 8 oz. Styrofoam cups and punching a hole through the bottom of them. This hole was for water entry or excess water drainage. Moistened soil was packed to the 1/2 full line in the cup along with 3 fertilizer pellets The cups were labeled the following: Rosette-H20, Rosette-GA, Wild-Type-H2O, and Wild-type- GA.(Handout 1) A small wooden applicator stick was obtained a moistened at the tip with water from the petri dish labeled ‘water.’ This was to be able to attract the seed to the applicator in order to place the seed from its original container into

Before, I started I made a prediction for the experiment. I thought the salt on top of the seed and inside the paper towel would soak up water and dehydrate the seed and make the paper towel go dryer

In order to control all of these factors throughout the experiment, one must randomly select the alleles (cheerios), must have a larger population size

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.

For the Mole lab, my team claimed there was 1,992 beans in the large display jar. The estimate was close but still off by 59 beans. The actual amount of beans in the jar was 2,051. To figure out our estimate we used a beaker of beans to experiment with. We first found the tare weight of the beaker, which was 49.912, and the weight of the beaker with the beans, 95.301. Our next step was the weight ten beans of different sizes and find the average of the beans. We found the average weight of the beans to be .47g. After doing this we then subtracted the weight of beaker with the beans from the tare weight to find the weight of the beans. We found the weight of the beans to be 45.389g. After finding the weight of the beans we dived that by he average weight of our ten beans and got 97 beans in our beaker. When we counted our beans in our beaker, we found it to be 105. We then repeated this test but using the tare

First students obtained 8 graduated cylinders and labeled them. Each one contained a different ratio of vinegar and water. These graduated cylinders with the liquid were weighed and recorded.Then, students obtained an Alka-Seltzer tablet and recorded its mass. Then one alka-seltzer tablet was dropped into each of the graduated cylinders. Students had to

I filled three clear cups, the first one with dH2O, the second with 0.1% NaHCO3 solution (equal parts 0.2% NaHCO3 and dH2O), and the third with 0.2% NaHCO3 solution. The control of the experiment is the cup with dH2O. The independent variable is time and the dependent variable is the number of disks floating in the solution. We separated the 30 disks into three groups of 10, placed them in syringes filled with a corresponding solution (either dH2O, 0.1% NaHCO3, or 0.2% NaHCO3), and removed all air from the syringe. This causes photosynthesis to stop in the disks, which then causes the disks to not float any longer. The three groups of disks were placed in each cup filled with 100mL corresponding to the solution, then placed under a light source and started a timer. For each minute in 15 minutes, data regarding the number of disks that floated to the top of each

There are many procedures during this lab and many materials needed for an accurate analysis of data. First, fill a 100 mL graduated cylinder with 50 mL of water. Add 25 germinating peas and determine the amount of water that is displaced. Record this volume of the 25 germinating peas, then remove the peas and put those peas on a paper towel. They will be used for the first respirometer. Next, refill the graduated cylinder with 50 mL of water and add 25 non-germinating peas to it. Add glass beads to the graduated cylinder until the volume is the same to that of germinating peas. Remove the beads and peas and put on a paper towel. They will be used in respirometer 2. Now, the graduated cylinder was filled once again, determine how many glass beads will be require to reach the same volume of the germinating peas. Remove the beads and they will be used in respirometer 3. Then repeat the procedures used above to prepare a second set of germinating peas, dry peas and beads, and beads to be used in respirometers 4,5,and 6, the only difference is the temperature of the water.

In generalization, there are a multitude of factors that could potentially influence the germination of a radish seed. This lab thoroughly exhibits the effect of water amounts on the germination of a radish seed. There is indeed an in-depth science behind the projected results, and overall of the effects water has on the germination of radish seeds, and the growth of plants in particular. Radishes themselves are moisture-loving plants; therefore, it is significant that they receive an adequate amount of water, allowing the soil to be moist, but not overly saturated (Biology Coach, 2015). In general, water is significant for the health of a plant in the way it transports important nutrients throughout the plant. From this point, nutrients are drawn from the soil and used by the plant. Seed germination itself is defined as the process where the seed sprout for growing, and future development into a plant. In order to germinate, the seed must have its essential needs met until it is capable of doing so: water, temperature, and sun. Therefore, during its early stages of growth, the seed will rely upon the food supplies stores within it, until it is large enough for its own leaves to begin making food through photosynthesis (Biology of Plants, 2016). Initially, the process of germination begins with the absorption of water y there seed, therefore, this absorption of water then activates an enzyme that increases

The low-density radish-collard mix pots contained four seeds of radishes and four seeds of collards. The high-density radish-collard pots contained 32 seeds of each species. While our group replicated this 3x2 design four times to total 24 posts, we incorporated the whole class data. Therefore, there were 16 replicates for each treatment. For each pot, we filled soil up until about one inch from the top. We placed the seeds in the pot and piled on around 2 or 3 cm of soil on top. In 3 species levels, seeds were spaced as evenly as possible. In the mixed species pot, the two species were alternated so that each one had the same access to space and nutrients at the other. For each pot, we wrote down our section number, group name, and the contents of the pot. Our group worked at the first bench in the greenhouse and also contained our pots that were spread out evenly in four rows. Our pots stayed in the greenhouse for about five weeks, captured as much sunlight as they could, and got their water source from sprinklers that automatically came on twice a

The third step that was taken was germinating the seeds. Two sets of paper towels were used to germinate the
