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

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.

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).

In this experiment, the original bulb C was faulty and did not grow any roots, even in the same conditions as the other three onions. This defective bulb caused the data for bulb C to be a day behind, as it had to be replaced with a new onion that did not start growing until a day after the others. This also meant that its growth was stunted by caffeine at a different stage which may have changed results even more. Another experimental error in this lab is the problem with overlapping cells. When the onion roots were smashed to be viewed under the microscope, some of the cells were overlapping.

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.

All other variables were controlled in order to ensure the trials were kept consistent, minimising the occurrence of any unusual results. This was reflected as the results of this experiment were consistent and indicated a trend, with no obvious outliers observed. Each method of collecting the rice grains was repeated three times in order to ensure this experiment was reliable. Repeating the experiment more times would have yielded a more accurate result however, due to the time constraints this was not possible.

10 plants were grown in separate pots so that they could be treated with different pH solutions. The pots consisted of 3 control plants, 4 plants treated with a pH 5 solution, and 3 plants treated with a pH 8 solution. To growth the plants a seed was place 1 ml beneath the surface of soil inside a pot and then watered. One weed was given to allow for the plants to sprout before being treated with pH solutions and the fertilizer. After the initial week for growth, each plant was given the fertilizer by diluting 1 ml of concentrated fertilizer into a mason jar of water.

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.

This experiment will also show if fertilizers help a plant grow more than just soil found in nature. This experiment will not try to prove if chemical fertilizer is safe or not. The chemical fertilizer being used was randomly chosen and the compost will be made from scratch. There are positive and negative effects on the plant from using both these fertilizers. The best result will be determined through daily measurements and general observations of the appearance of the
