The data observed and recorded in this lab shows that the concentration of miracle gro’ does affect the growth rate and germination speed of black eyed peas. The data is shown through two graphs and two data tables. The control group in this experiment is the seeds with a 0% concentration of miracle gro’, therefore the seeds with just water. The experimental groups are different concentrations of miracle gro’ including a 10%, 15%, 20%, 25%, and 30% concentration. The variable in this experiment is the amount/concentration of miracle gro’. On day one no seeds germinated. By day two, seeds in the control group, 15% and 25% experimental groups had germinated. On day two the experimental group with 25% concentration of miracle gro’ had the most seeds …show more content…
Human error played a factor because it was not made sure that air was trapped in each bag. In the class data the amount of seeds germinated on day three was higher than the amount of seeds germinated on day four. This is not possible as the amount of seeds germinated cannot decrease, rather they should stay the same or increase. A seed cannot go from being germinated to not being germinated. This could have occurred from miscounting or not accurately counting the number of seeds germinated. If the experiment was completed again, more higher concentrations could be applied to the seeds to see if the data is further supported. Either way the more trials the better and more accurate results, this applies to any experiment. Practical applications of the principles of this investigation may be using the correct concentration for a specific plant or seed. This lab shows that it is necessary to follow the directions and specifications when using the fertilizer miracle
First test, Morphological of Unknown consists of multiple of subtests. First subtest was used to determine the optimum temperature of unknown #398 growth by inoculation into 2 nutrient agar slants.

Introduction- We did an experiment about different types of movements called kinesis and taxis. Kinesis is the change in the speed of movement or the rate of turning which is intensified by a stimulus (Meyer, 2006). Taxis is movement towards or away from a stimulus (Meyer, 2006). We did our experiment using Sowbugs.
We made high and low density treatments of ten seeds and two seeds respectively. Each treatment had water, soil, and fertilizer. The height and survivorship from each treatment was averaged over four weeks. These results show no significant difference between the high and low treatments.
The purpose of the Plant Mineral Nutrition Lab was to grow Helianthus annuus plants also known as sunflower seeds in order to see the effects that nitrogen has on its growth. The first week, Helianthus annuus seeds were planted into a perlite. A week later, a beaker was given and the stock solutions for high nitrogen was used. In order for high nitrogen, the eight stock solutions were doubled. After the right amount of stock solutions was added, distilled water was added to reach the final volume.
For any seeds that did not germinate, the seed length was measured and used towards the data. The plant heights were put into a data table and a mean was found for each level of I.V. for further data analysis. Then, all of the steps from placing the seeds into the microwave to adding the plant lengths together for the final data, including those two steps, were repeated four more times for a total of five repeated trials. Next, all of the steps from placing the seeds into the microwave through the step preceding this one, including those two steps, were repeated for a total of five repeated trials for all remaining levels of I.V., excluding the warm water level(100W for zero seconds, 500W for 30 seconds, 900W for 30 seconds). Finally, all of the plant lengths, including those that did not germinate, were added together for the final
There is no doubt that fertilizers increase yields of crops around the world. Use of modern fertilizers exploded after World War II. New, ammonia-based fertilizers
However, after investigation through gel electrophoresis, the three kinds of plants were not identical. This relates to the
However, our experiment was to test if the amount of water used to water each crop was unnecessary. We watered a group of plants with the average amount of water used in farms, watered a group of plants with a little less than average, and watered a group of plants with a small amount of water. We normally watered the plants with the average amount until all of the plants germinated. After the plants germinated, we started our experiment and controlled the amount of water. After about two weeks our experiment was over.
The objective of the sludge lab was to determine how many different pure substances were in the sludge by using the methods and techniques we have learned throughout the year. We had to pick separation methods so we could separate our sludge and then test characteristic properties on our separated liquids and solids. This experiment made us use our knowledge on characteristic properties to pick the ones we should test to help us identify our pure substances. Characteristic properties are properties that help identify a solid or liquid. Each solid or liquid has a certain density, boiling point, solubility, flammability, so if you know what each one is then you can use that information to help you identify your solid or liquid.
As farmers have to mass produce in order to supply for the growing population today, fertilizer is essential to improve the quality and growth of the
This scientific question is, does the different kind of gum increase or decrease your concentration? This question was chose because many people in the world always are looking for some tips on what helps them concentrate, and chewing gum is a very easy way to help improve concentration. The Independent Variable is the type of gum, the Control Group is Bubble Gum, the Experimental Group is the Spearmint, the Dependent Variable is test scores, the Constant Variables are same timed test, same timer, and same brand of gum. The hypothesis for this science fair project is if spearmint gum is chewed then the person's concentration will be increased. This hypothesis was picked because spearmint gum is minty and the scientist thought that maybe mint impacted the brain the most.
The plants with 200 ml topsoil were projected to have the highest average height according to the original hypothesis of increased plant growth due to an increase on the amount of topsoil added. Moreover, the original hypothesis was refuted as the plants with no topsoil in the control had a higher average height than the plants with 25 ml topsoil. The mixed red and green color on the leaves of the plants with 25 ml topsoil indicated possible deficiencies in phosphorus which might have slowed their growth. Moreover, the mixed red and green color on the leaves of the plants in both 100 ml and 200 ml topsoil also indicated a possible phosphorus deficiency which may have resulted in the slower growth of the plants despite having greater amounts of topsoil. The experimental results might have skewed due to the over fertilization of the radish seeds which might have led to excess nutrient levels which are unsuitable for radish plants as they require little to no fertilization for growth (Chase, 2018).
Fertilizer is definitely necessary in the modern age, and no scientist in the right mind will tell a farmer they should stop using fertilizer. There is an optimal amount of fertilizer to be used and this experiment will find
.05 grams Measure of time +/- .5 seconds The same degree of uncertainty was added to each trial of each plant. This is because the same materials were used for each one. One limitation of the lab was the fact that the leaf disks of the plant Solanum lycopersicum were very thin.
