Grass Grow Lab

In this experiment we are testing the effect of fertilizer on the speed of plant growth. We prepared a 4 quad cell, 1 control group and 3 experimental groups. So, we had one with no fertilizer, one with three seeds of fertilizer, one with six seeds of fertilizer, and lastly, one with nine seeds of fertilizer. The plants that we grew were called Wisconsin Fast Plants, members of the crucifer family. These plants are small and easy to grow, but for optimal growth they require continuous fertilizer, water, fluorescent light, and temperature between 18 degrees Celsius and 26 degrees Celsius 24 hours a day. Fertilizers are substances that are put into soils to increase the growth of the plant. There are two different types of fertilizers, synthetic

In site C the data being collected throughout the 5 days showed an increase in the growth of the radish seeds. Day one stayed at 0cm because it was the starting day of the experiment. Day 2 the growth was 1 cm 9/10 cm 3/10cm 0cm 0cm. Day 3 the data showed the growth of the seeds at ½cm 0cm 0cm 1cm 4/10 cm. Day 4 the data showed 5cm 2/10cm ½cm 1cm 0 cm 0cm. Day 5 the data showed 6cm 1cm 0cm 0cm 1cm. The data is important because it shows the landfill isn't the reason why the crop failure occurred

There are many ways to obtain seeds to grow flowers in the springtime, but not all seeds were created equal. Sunflower seeds, for example, can be bought at a garden store in a packet for $1.5 dollars per 6 gram packet, but they can also be found in bird seed for $3.53 dollars per 10 pounds. This experiment intends to find if the germination of a store bought packet of sunflower seeds matches the germination rate of sunflower seeds obtained from a bag of bird seed. While both seeds will germinate, it is believed that the bird seed will not be as robust in growth as the garden seed, due to the fact that the garden seed is made to be grown, while the bird seed is made for consumption.

The results observed do not correspond with the outcome predicted by the hypothesis. Despite the nature of the subjects of the experiments, no substantial growth was observed. Only one seed of the 36 planted germinated, and it could only survive for a period of a week. The one seed that germinated reach a height of 1.2 cm. Table 1 presents the average growth observed in each quad. Each quad had a total of 12 seeds. No seeds were removed during the course of the experiment.

That journal went into great detail in the statistics of the survivability rate of the plants. On the other hand, some of my sources came from United States agencies such as the Department of Energy or NASA showing statistics on energy production and its efficiency in space.

The group planted a total of 8 separate pots of seeds. Two pots consisted of only seeds and those were the control group of this experiment. The other plants also consisted of radish seeds but had chemicals ammonia, vinegar, or a combination of both applied once weekly with 30ml of water being applied daily (except on the weekends). As a result, there were a total of 8 pots. Two of each variable and two of the controls.

A reason as of why the experimental group grew taller would be that maybe the seeds in the control group did not get as much water as the experimental group did. Although there was a controlled amount of water put in each petri dish, there was an extra layer of paper towel on top of the seeds in the control group dish that could have soaked up more water than the experimental group. This factor could deprive the seeds of necessary water, therefore making the seed germination process much harder and could take longer. Also, there was one seed in the control group that did not germinate at all. The water could possibly not have reached that seed in particular. The water was most likely absorbed in the paper towels or other seeds before it even reached that seed in particular.

The second step of the experiment was to soak the seeds in water overnight. This action was made to prepare the seeds for germination and making them more softer and less rigid. The seeds were placed in a bowl and were covered by tin foil. It was set up on the refrigerator to minimize any outside interference that may come to it. After a full night of absorbing the water, the seeds were ready to start the next stage.

3. For the most part, the design of our experiment was pretty good. One weakness I think we had was our constant. I think we would have had a better constant if the seeds in the Natural Light category were actually outside,

The aim of this practical was to test whether a Scarlet Globe Radish will grow higher in cm when watered using different types of water and the hypothesis was that scarlet globe radishes should grow higher when watered with sparkling water as it contains co2 however that hypothesis was proven incorrect. From results it can now be concluded that the control patch surprisingly produced the highest plants in terms of height with an average ground to leaf height of 2.2 cm while the sparkling water patch produced 1.86cm and the filtered water patch with an average height of 1.18. However, from research it was shown that sparkling water was more likely to make radishes grow at a faster rate. A faster growth rate would’ve made the radishes taller

All of the plants involved in the experiment, Marigold, Squash, Radish, and Wisconsin Fast Plant, all were affected by the radiation from Cobalt, but some more than others. The plants all followed a similar trend, which was when the radiation amount would increase, the amount of growth would decrease. In the Marigold plant, the germination percentage for 0 KR started at 54.88%, but increased to 64.55% at 50 KR, before starting to drop it’s percentages lower as the KR amount went up. The squash plant had a continuous drop starting at 69.53% at 0 KR and dropping to 36.72% at 500 KR. The Radish plant started at 81.64% at 0 KR and dropped to 30.73% at 500 KR. The Wisconsin Fast Plant started at 85.16% at 0 KR and dropped a little bit to 64.71%

The conditions of the experiment were highly controlled with the exact same greenhouse, watering system, roof, time, same kind of plant. While there were some very small variables the main variable was the music and sounds played inside the greenhouse during the duration of the plant growth. The different variables to test the growth of the plants was the type of sound used in each greenhouse, the sound was separated into: heavy metal, classical, angry insultful talking, caring loving talking and no sound at

Plant four seeds in each pot. The seeds need to be planted 1 inch in depth and 2 inches apart. The seeds do not touch the fertilizer. This can damage the seeds. Place enough of the potting soil in the container to cover the seeds. Water each pot with a liter of water. Water the plant sparsely and only when the top two inches of the soil is dry. Divide up the pots where 5 pots get the correct fertilizer, 5 without the correct fertilizer, and one potted plant doesn't receive any fertilizer at all. Group A are the potted plants that receive the UltraGreen fertilizer. Group B are the seeded pots that contains the incorrect fertilizers. Each pot is labeled with the brand of fertilizer used. Group C is the potted plant that receives no fertilizer. The seeded plants were placed in full sunlight. Plant measurements will be conducted at 4:00 pm every day. The positive control group were the seeded pots with the UltraGreen fertilizer. The negative control group were the seeded pots with all the incorrect fertilizers in them. Set the pots in the same location outside. All plants were exposed to the same temperature. Water the plants equally and regularly as needed. Beginning May 1, count the number of flowers. Put data in week by week. For example, week 1, the plant has grown 1 millimeter but no

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

I believe ways to make this experiment better would be the amount of days and the amount of plants. I believe having more than 35 days would give me more time to measure more data to make an accurate experiment. I also believe more plants, instead of 5, would help you get a more accurate measurement with the exception of natural causes. With these being extended it would help me get a better example of Radiation VS Plants. Overall the amount of water, sunlight, and soil would stay the same along with the Plants and days would be changed. Also next time I would be more descriptive on how I describe the plants appearances. Like how many leaves, what shape are they, what is the texture. Now we know, plant radiation does affect a plants growth, too much of it, will kill the
