Aspirin Water: The Effects Of Medication On Plants

All five groups recorded the outcomes that they established. For our bench, we found that nine raddish seeds in the control dish, zero raddish seeds in the eucalyptus dish, and four radish seeds in the lemon dish germinated and sprouted. Our bench also found that the average seed length for the control was thirty one millimeters, for the Eucalyptus was zero. and for the Lemon was eight and a half. Below, is a chart and graph that shows the whole data as averages from all five benches. Each bench did the exact same experiment so we knew nothing would be biased.

The hypothesis behind this experiment is that the Gibberellic acid has a positive growth effect on the plant and causes it grow larger in height.

The hypothesis that was tested was pill bugs are use to the cooler temperature of the room and natural soil would travel a greater distance once they were in a hotter environment. The hypothesis is rejected on the basis that the p-value of .760 is greater than .05. Furthermore, figure 3 supports this rejection, since the averages are very close to each other and their error bars completely overlap. This rejection means that once the pill bugs where in the hotter environment there was not difference in their behavior compared to the cooler room temperature environment; they did not travel longer distances. However looking at bugs D, F G and H in figure 2, there is a difference in distance traveled that appears to be greater than

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.

This project was to see the effect that caffeine would have on plants. This project was to figure out which amount of caffeine was to make the plant grow the most. The test subject plants that were used in this experiment was Basil. Basil is a plant that sprouts very quickly. It is supposed to sprout in around 10 days. The plant Basil has no caffeine in it to start with. The only plant that has sprouted was the control plant that had no caffeine in it’s soil at all. We used caffeine tablets instead of coffee grinds which are more natural because they are high on nitrogen. There was two with 400 mg of caffeine in them. Next there was two plants with 800 mg of caffeine in them. Lastly there was two plants with 1600 mg of caffeine in them. In

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.

In our Penny Lab, we wanted to extend what we were told to do with experimental design. We’re doing this because we wanted to prove what he thought our hypothesis had been, and a hypothesis can not be true unless it can be tested. We investigated what variables made the Penny Lab easier, or harder. As a class we decided to investigate variables like, dropping the penny from the same height, and applying the same pressure to the penny for each drop. But first we had to know what variables were, and which variables we needed to use in the experiment. The variables were, the independent variable, dependent variable, the experimental group, and the control group. We investigated this to show how much water a penny could hold, but we introduced

Null Hypothesis – A plant on a window sill does not grow faster than a plant on a living room coffee table

After finishing the entire lab experiment, I find that those were the only big problems I had. If I were to improve this experiment, though, I would find a good window ledge, buy a tape measure and have a better object to block the experimental seeds from the sun. Other than these factors, I feel this lab went very successfully and that the results were reasonably accurate.

Each quad of soil had 2-3 seeds in it along with either 0, 3, 6, or 9 pellets of fertilizer in each quad to possibly get 4 plants total. Two types of fertilizer exist, organic fertilizer and synthetic fertilizer. Gardeners.com says that, organic fertilizers are made from organic materials. (1) Organic fertilizers also prevent the plant with a better structure, improving the structure of the plant. (2) Synthetic fertilizers are fast-acting fertilizers but also come in different forms such as granule, spike and pellet. (2) This kind of fertilizer is also known for seeing green in the plants quicker and quick-hit of nutrients for the plants. (2) There are advantages and disadvantages of using fertilizer. Plants can have a quick action of growth and are more defined when using fertilizer. (3) But sometimes there is a chance of using the fertilizer to much causing damage to the whole soil ecosystem. (3) Over two weeks we observed the growth of the fast plants and recorded the data of the height. By the end of the two weeks, we also recorded the weight of the fast plants. I hypothesized that each quadrant was going to be different plant growth, with the quadrant of 6 pellets (quadrant C) being the fastest growing plant. My individual results showed that the quadrant with 9 pellets (quadrant D) had the most results with growing in

Dependent variable- jar volume after the egg is out (ml). Controlled variables- jar, same amount of water and corn syrup, same number of days it stayed there, same grade egg, same process, same surface we put them on. The experimental group are both the eggs because they both got tested on. We didn't have a control group because we didn't have an egg that didn't go through a test. The experimental group is the group you experiment on. The control group which doesn´t get tested

The pill bugs lab was done to solve the problem of which type of food the pill bugs preferred, cucumber of pepperoni. My hypothesis was that the pill bugs will favor cucumber over pepperoni. In order to carry out this experiment, we used the chamber method to determine which food was favored by the pill bugs. Pieces of cucumber and pepperoni were placed on each end. Then five pill bugs were placed in each chamber, and their movement was observed and recorded. Because the results were so close to each other, we concluded that their reaction to the stimulus was a kinesis reaction, and it is only random. My hypothesis was not true because the standard error from the number of pill bugs in cucumber chamber and pepperoni chamber overlapped. This means that there is no scientific reason for why the pill bugs chose cucumber over pepperoni. I learned many new things in this experiment, such as, how to use a choice chamber, and how to calculate the standard deviation and error of the data. Also, I learned how pill bugs react to an outside threat.

In our experiment, we studied if sugar make kids hyperactive? We did the planning and execution together. Our prediction was that sugar would increase their blood pressure and would weaken their concentration and memory. Our experiment showed us that the myth and we were wrong. If we had had more time, if we had given them more sugar and if the subjects were younger the experiment results would be much more accurate. Even though our subjects were not young kids and we had a limited amount of time and therefore a limited number of subjects I can say that we busted the myth successfully.

While conducting the research the researchers did two experiment. In both the experiment the researchers subjected undergraduates of two different university each time. The students received course credit for their time in both the experiments. The researchers wanted to see if they could implant false positive belief in the subjects regarding a specific food item (asparagus) as children. Asparagus was chosen as a food item because it is a healthy vegetable with rather sophisticated taste, and so many most children would not like it immediately. In experiment 1 the researchers wanted to see if they were able to plant false belief about asparagus in the subject and see if the false belief had effects on the subjects later such as increased likeliness towards asparagus, willingness to eat asparagus in a restaurant setting and also memory or belief of the people eating asparagus as children. After experiment 1 was conducted, researchers wanted to know if the pictures of the asparagus seemed more appetizing or

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