The factors that could have affected this experiment are endogenous, which are frequently correlated with environmental changes such as light, temperature, and relative humidity. They were taken from their natural habitat and put into a room with different temperature and lighting than what they are used to. Another factor to be considered is that although many species are active during a certain period of day or night and are quiescent for the remainder of the 24 hours, some exhibit different…...

Viscosity Of Water Lab Report
The distance at which the sphere was dropped from, could have affected the terminal velocity. By doing a reverse engineering calculation using the equation given in the lab sheet for Castro oil (0. 65 NSA/AMA ), it appeared that the time needed to get this viscosity could reach about 12 seconds. This was quite impossible in our experiment to be obtained. Accordingly, one possible justification for this problem could have been the liquid unknown type, which we assumed to be…...

Egg Drop Physical Experiment Essay
In our physic class we did an egg drop experiment. We used some vocabulary words to answer the question also did formulas to solve some problems. The question that we are referring to is “will an egg break or be secured”. Our idea was to secure the egg from breaking and we wanted to design something that would provide a lot of cushioning directly on the egg. So we came up with many different ideas until we chose the one…...

Agar Cell Diffusion Lab Report
Hypothesis: I expect to find that when the surface area o volume of a cell reaches a certain level, diffusion alone won’t be able to supply the cell materials needed, and as single-celled organisms take in and release substances by means of diffusion across the cell membrane, this process limits cell size. I predict that as the rate of diffusion will be too slow to deliver materials to the center of the cell in the larger cells, it could result…...

Surface Tension Of Water
The capillary rise method was used to measure the surface tension of aqueous solutions of sodium chloride and acetic acid. Molar concentrations of 0. 5 M and 1. 0 M for each solution were tested. The results were then compared to the surface tension of pure water to observe how solute properties affect the surface tension of water. The experimental results showed that adding acetic acid solute in water lowers the surface tension of water. As the concentration of acetic…...

Target identification and feature integration theory
The effect of distractors on target identification was studied using 118 participants, from Warwick University. The experiment was based on work done by Treisman and Gelade (1980), who developed the feature integration theory. Each participant completed a visual search computer program consisting of three conditions. As well as these conditions as a factor there was also the varying display sizes such as 4, 8 and 16, and with the target being either present or absent in the trials. The mean…...

Based on Treisman's attention theory and his attenuator experiment which claims that all messages reach the selective filter where one message is selected to pay attention to. Treisman, a colleague of Broadbent thought that all other messages which reach the selected filter are not blocked out but are instead turned down, known as attenuated. Within my experiment I hoped to find out whether it takes longer to complete a card sorting task with distracting noise than in silence. I predicted that…...

Does Our Radioactive Modeling With Coins Illustrate Radioactive Decay?
I believe that it is possible to illustrate radioactive decay by trying to model it using coins. Radioactive decay is a random process and is not affected by external conditions. This means that there is no way of knowing whether or not a nucleus is going to decay within a certain period of time. However, due to the large numbers of atoms involved we can make some accurate predictions. For example, if we start with a given number of atoms…...

IB Physics HL Lab Report on Projectiles
Even if the actual measured results differ sensibly from the hypothetical values, we can clearly see that an inclination of 45 degrees generates a much longer distance travelled horizontally. During our experiment, water pressure was not constant and there could have been some fluctuations due to wind variation. Those uncertainties must be taken into consideration. Conclusion and Evaluation Our mathematical proof and hypothesis were right that in parabolic motion, 45 degrees offers the greatest horizontal distance travelled. The values recorded…...

Effect of Concentration on the Rate of Reaction
In this experiment, we utilized the ability for the iodide ion to become oxidized by the persulphate ion. Our general reaction can be described as: (NH4)2S2O8 + 2KI A I2 + (NH4)2SO4 + K2SO4 (1a) However, we know that in an aqueous solution, all of these compounds except iodine will dissociate into their ionic components. Thus we can rewrite the equation in a more convenient manner: S2O82- + 2I- A I2 + 2SO42- (1b) It is important however to note…...
