Black Tea Lab Report

The growth and survival of a plant depends on the reactions that occur internally called photosynthesis. Photosynthesis is a reaction that captures the sun’s energy and converts it, water, and carbon dioxide into glucose, with a byproduct of oxygen. Glucose is a sugar that provides energy to allow for a plant to grow and live. This experiment is to test how photosynthesis can be sped up with a home solution. The variable being changed in this experiment is the solution that the plant is being given. In this instance, some of the plants will be given Gatorade, rather than water. The question being asked is, How well will a solution found in the home affect plant growth?

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

Add three seeds to the potting mix and cover seeds with little remaining potting mix. After the addition of the potting mix, use a dropper filled with water and water each cell until water drips from the wick. Then place the quads on a watering tray under the fluorescent light bank. Each cell should have an equal distance from the light bank. Quads should be three inches below the fluorescent light; the light should also be left on all day. Make sure all wicks are in contact with the mat that sits on the watering tray. Also watch out for the watering system regularly throughout the experiment. After four to five days record plants in the quads, giving their phenotypes in a table for each cell removed all but the strongest plant.

Right after all the seeds were germinated in petri-dishes they were put into pots, covered with soil, and labeled to prevent confusion.

The third source of uncertainty would be the ruler used to measure the seeds. The uncertainty of the ruler used was ±.05 cm. The next step for this experiment would be to allow more time for the growth of the seeds. Therefore, instead of focusing on the germination of the seeds, one could also study the flowering of the plant and observe whether the value of pH continues to affect the growth. To ensure less uncertainty, the 2 batches of seeds could start on the same day to allow the same allow the same amount of sunlight.

Data Description: In both the bleach and vinegar soaked seeds, there was no growth whatsoever; therefore, there were no trends or changes in seed growth to be accounted for. The beer soaked seeds did relatively well, growing at a steadily fast pace, and grew more healthily than the other seeds (besides the control). On the graph, the beer soaked seeds seemed to follow a type of pattern. From point 1 to 2 and point 2 to 3 it inclined at the same angle.

We noted if any plants died, how dry the tray looked, and various other observations. Final measurements will be taken on April 12, 2016. Final measurements include: the length of the stem, stem length from the korm, weight of the korm, steam weight without the leaves, and stem weights with the leaves. To find the growth of each treatment, we will divide the final date by the initial data collected. Specifically, our group will divide elephant ear growth by Iris growth. So, we will compare the growths of the EI pots. If the proportional of elephant ear versus iris is bigge than 1, this means that the Elephant ear grew larger than Iris. We can then input the data into the respectable ANOVA tests and Post Hoc tests to further analyze our

For all six plates, the same two types of seeds were used, Radish and Basil, and the hormone used was Gibberellic Acid. The six plates were all prepared on March 5 and given their specific

Graph 1 in appendix A shows the plants took a couple of days (7-10) to grow because they had to germinate. But on day 7, the water plant was 1mm and grew to be 2 inches. The Detergent plant grew to 1mm, and the Dish soap plant grew to 2mm. The data does support the hypothesis.

Seeing as quad one is the control group, no fertilizer was added, giving only natural occurring results. Within the experimental groups, three fertilizer pellets were added to each cell in quad two, five fertilizer pellets were added to each cell in quad three, and ten pellets were added to each cell in quad four. The dependent variable is the growth of each Fast Plant, seeing as any one of the independent or dependent variables could have an impact upon the final results. The control variables include water, potting mix, light, number of seeds, as well as container size. After researching the life cycles of Wisconsin Fast Plants, a final hypothesis was made that based on its known genetics, the quad with the most fertilizer pellets would grow at a more rapid rate than the remaining three. It was concluded that the benefits of fertilizer added to the already rapid growth of the Fast Plant, would further speed up its life

The purpose of this lab was to see if radiation has an effect on the cultivated radish seeds that we used. From the observed data that we collected, we were able to conclude that when seeds are exposed to radiation, it affects how they grow, if there is any growth at all.

The hypothesis made at the beginning of this experiment was not supported by the data collected throughout it. While none of the plants showed growth, the plants in the control group showed the least amount of decline. This does not exactly the fit the hypothesis of which plant will grow the most, but the data proves that the other groups showed more of a decline than the control group, making it the best way to grow the plants. As mentioned earlier, the plants in the control group decreased an average 0.202 grams, while the groups grown in stones and wood decreased approximately 0.1 gram more. Along with that, the data shows that the control plants increased an average of 0.0 centimeters in leaf length, which

This lab was a success, because it shows what happens with acid rain, and its effect on seed germination. The seeds will actually grow
