Question How does changing the size of the airplane affect how far the airplane goes. Hypothesis If we change the size of the airplane then the paper airplane will go further. Materials Paper, graph paper, meter stick, a pencil, Procedure: 1.I will build two identical paper airplanes. One will be my control airplane that is smaller and the other will be my test airplane the one that is bigger. 2.I will throw my control plane 10 times and I will use a meter stick to measure the distance of…

If 5 cuvettes containing spinach/DPIP solution are covered with different cups so that they absorb light of different wavelengths, then the cuvette with no filter will transmit the most orange light because it has been exposed to all white light and has the fastest rate of photosynthesis, followed by cuvettes under red cups, blue cups, green cups, and finally under the opaque cup because it has been exposed to no white light and has the slowest rate of photosynthesis. Fig. 1 and Fig. 2, which…

The main objective of this study was to determine whether the rate of cavitation in xylem channels correlates with tree height by measuring the water tension from leaves at the top against leaves from the bottom of Acer Platanoides (Norway Maple) trees. We hypothesized that water tension would be higher at the top of trees than at the bottom. The secondary focus was to determine if varying water tension would affect the structural composition of leaves. In order to identify a relationship, we…

Technology is becoming more prevalent in education. Technology can be used as a great resource in the classroom. There are many studies today about the effects on technology on student learning. There are also many studies on peer feedback in student learning. Yu-Fen Yang and Wen-Ting Meng from Nationals Yunlin University of Science and Technology wrote an article called, “The effects of online feedback on students’ text revision.” This article goes through a research study to see if explicitly…

Discussion: The distribution of each graph is quite comparable as they have similar means and standard deviation, where the preferred hand has a mean of 16.33 and a standard deviation of 2.842 whilst the non-preferred hand has a mean of 17.2 and standard deviation of 2.848. The normal distribution graph of each can be seen below: Preferred Hand vs. Non-preferred Hand: The graphs and boxplots (Figures 1.3- 1.6) seen previously in the results indicate that the two results did not have a normal…

also exhibit elevated inattention. Inattention. First grade teachers will rate students scoring below benchmark scores on the ADHD-IV Rating Scale and the Social, Academic, and Emotional Behavior Risk Screener (SAEBRS). Students who a score 1.0 standard deviations above the mean on the inattention subscale of the ADHD-IV Rating Scale will be included in the study. The SAEBRS will be used to determine if a brief universal behavior screener identifies the same children as the ADHD-IV Rating…

Handedness is dominance of one hand over the other , or the unequal distribution of fine motor skills between right and left hands. It refers to the tendency of humans to be more dextrous or skilled with one hand over the other. By self report the rates of right , left and mixed handedness are 56.1%,26.3% and 17.5% respectively. The rate of handedness conversion is 2.7% to 11.8% in prior studies based on the total population including innately right handed people. The rate of conversion of…

III. The Second Negotiable Field: Environment 1. Importance of Environmental Problems In Korea and Japan, both the industrialized and democratic countries, the environment has emerged as a high priority issue. They have experienced rapid economic growth, but have along the way encountered serious environmental problems. These societies now share the idea that, if they do not preserve natural environment, their economic development would be unsustainable. It would be politically impossible for…

Mascara Task Introduction In this investigation task, two mascara brands were compared to see which mascara brand was of higher quality overall. Questions considered in this investigation include how long good quality mascara lasts, and when the most appropriate time to apply mascara was. Mascara is measured by the average thickness in millimetres and this model is then considered over a number of hours. Aim To determine which mascara brand is more efficient over time. Hypothesis The Fuller…

table above the mean, median and standard deviation will be calculated. The mean equals the average of the sample by adding all the values of the samples and then dividing by the total number of items. The mean for the samples collected is 14.87 ounces which rounded up 14.9 ounces. The median is calculated to be 14.8 ounces. The median is calculated by averaging the data in order and finding the midway point of the data set. Last to find is to find the standard deviation, which is the…
