The trend, shown by the line of best fit, indicates clearly that exposure to UV light harms the growth of the sprout, delaying the process. The sprouts that received the full exposure were harmed the most, followed by the half exposure and then no UV exposure, only a household lamp light. Interestingly, the sprouts of all 3 different light exposures manages to grow up to a reasonably healthy height, was healthy in pigmentation and did not wither under different lights. The
The method of the experiment changed because a battery-powered UV light source was used. This was found to be unreliable as the battery would run out after only a 2-3 days which meant this experiment had to be restarted. This occurred twice and in order to keep the experiment
Difficulties in the experiment arose when inverting the buret and completely submerging it into the beaker of water. This is a likely place for error because
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 video I choose to watch on sproutflix.com was called Check Out. The video was about a woman named Kelly, who has down syndrome. She had been working as a bagger there for six years. The video opens with Kelly asking a woman if she needed help taking her bags to her car. The woman was completely oblivious to her question because she was watching another male worker named Jerry.

Gram bowl provides a variety of choices of sprouts for the consumers. The consumers can customize their bowl of sprouts according to their taste. They can choose from at least 5 different sprout varieties and can opt for the spices that they want to add. The price is competitively placed and is leading the market. The customers are also offered complementary products like Lemon or Tulsi Tea which they can purchase as a combo or
To take action, one must decide if there is enough evidence to implicate the alfalfa sprouts and sufficient information on which to take action. Although the investigators had solid epidemiologic evidence to implicate the alfalfa sprouts at this point, the main difficulty with taking action was insufficient data to recall a product such as a lot number or sprouted. So, the team decided additional studies were necessary. In addition, a closer examination of the twelve cases that reported not eating alfalfa sprouts might be helpful in identifying other routes of infection. Changes in product processing (e.g., aseptic seed production methods, irradiation of seeds), if possible, are likely to be the most effective form of intervention in this instance. The other two require behavioral and attitudinal
Chickpeas are a popular type of legume that not only has anti-nutrients but also contains many nutrients that are beneficial to the human body. Soaking the chickpeas in an aqueous solution is a way to make chickpeas edible for consumption. The goal of this experiment is to determine the amount of moisture absorbed by chickpeas saturated in differently concentrated NaCl solutions. The chickpeas in the 0 M NaCl solution is shown to absorb the most moisture, whereas the 3 M NaCl solution is shown to absorb the least amount. In comparison the more dilute solution had the highest hydrolysis rate, whereas the more concentrated solution had the least. The amount of moisture absorbed is related to the k1 and k2 constants from the Peleg equation. The
Ultraviolet light will affect the growth of basil. The plant setup with UV light will grow faster than the setup without UV-B light. To determine whether the experiment is successful I will measure the speed of growth, the number of seeds that germinate after a certain amount of days. Another important factor to consider prior to the laboratory experiment is whether the plant is sensitive to UV-B light or not. Sensitivity is most noticeable with regard to alterations in plant growth and development (Teramura 1983). UV-B radiation can damage the DNA structure of the plant and generate growth issues to the cells of Ocimum basilicum. However, the perception of low levels of UV-B by plants might actively promote survival because it may
For this lab, we were tasked with answering the question, “Can UV light damage onion root cells?” In order to proceed with the lab, we needed to obtain clear images of the onion root cells, and be able to point out the differences in them when they are exposed to various time lengths of UV radiation. As seen with the results above, it can be concluded exposure to UV light does damage the root cells. This lab also has to do with how many of those cells are undergoing mitosis, and if the UV radiation hinders the cells from doing so. The mitotic index, a measure of this, shows how many of the cells are going through mitosis. The mitotic index was highest on the control or the zero exposure to UV light. The mitotic index slowly goes decreases
As previously stated, knowledge on this particular subject has been limited. Ever since Gause’s experiment, not many other scientists have attempted it until recently. As a class, the experiment was a way to observe competition and better interpret the results gathered
Spirulina has potential for being a ‘wonder food supplement’ and several leading organizations have praised its beneficial effects. In spite of the wide usage for the beneficial effects, a few side effects and contraindications have been reported with spirulina use. The most frequently reported adverse effects are headache, muscle pain, flushing of the face, sweat-ing, and difficulty concentrating. These have been described in people taking 1 g of spirulina orally. Skin reactions have also been reported. Spirulina should be avoided by people who have the metabolic disorder phenylketonuria, as phenyla-lanine content can be harmful.55 Although rare, cyanobacteria like Spirulina may contain toxins called microcystins, which accumulate in
Sprouts 2 had a terrific Tuesday! Today we continued to explore with bugs. In circle time with Ms. Dinah we discussed all the bugs we had caught in the bug catcher. Winston and Alexis was so excited so see the dragonfly! We also used the music sticks when we sung our good morning songs. On the playground we had a blast exploring in the sand box, sliding down the slide, and we continued to search for bugs to add to our collection. Caden was so excited when he found another bug to add to the collection! Back in the classroom we used crayons and construction paper to draw a picture of the bugs we found on the playground.
In this experiment, I tested the theory of how light would affect the growth of a bean plant. According to gardenguides.com, lack of light is detrimental to plant growth.”Plants that don't get enough light don't have the resources they require, and fail to bloom or fruit.” It is also stated that every plant will need a different strength of sunlight such as full sun, partial sun, or indirect sunlight (also known as full shade). Plants that receive inadequate amounts of sunlight will not thrive.The reasoning behind this is due to a process called Photosynthesis, stated in gardeningknowhow.com. Photosynthesis is a chemical process which converts energy in the form of light into a chemical energy which is a vital food source for plants to thrive.
Therefore, I was correct in my hypothesis that dark will have an effect on the germination of radish seeds. Also, I was very close in predicting that the seeds grown in the light will germinate twice as much as the seeds grown in the dark; the control seeds grew a little less than double the size of the experimental seeds. Ultimately, my experiment proved that light is a very important factor in the growth of any plant. However, I’ve learned that seeds grown in the dark will germinate, though slowly, as
The effects of light intensity and light wavelength on photosynthesis was observed in two different experiments and closer study of different pigments in spinach was observed. For the experiment where the effects of light was observed, it was found that a light intensity of 30 cm, wavelengths of blue and red lights show the greatest photosynthetic activity. The different pigments present is spinach were also observed and it was noted that though chlorophyll is the most abundant in plants, there are other pigments present as well.
