If the experiment had been undertaken in more controlled and technology used more efficiently‚ like a robotic catapult‚ than the effect of weight on the motion of a projectile would have become more apparent. Furthermore‚ the reliability of the experiment would be drastically increased due to the use of more accurate and more constant technology. Air resistance would of been a

Limitations Our experiment consisted of numerous limitation and uncontrolled variables which impacted on the validity of the outcome. These limitations include: the lack of repetition resulting in possibilities of outliers‚ inadequate temperature range and limited sample size at each group. The experiment also existed two other uncontrolled variables which are the size of liver and the amount of Hydrogen Peroxide‚ hence altering the authenticity of the practical result. At each of the five experimental

Marion Sims‚ “the father of Gynecology” performed surgical experiments on enslaved African women who were suffering from fistula problems‚ against their will‚ without any anesthesia. That is a very painful procedure to go through with unclean tools and no medicine to ease the pain. Only one out of thirty patients survived. In order to test one of his theories about the

The frame represented a simple roof trusses and the loading conditions are similar to what a typical roof would undergo. In this experiment a universal fame was used with load cells to provide the load and digital force and strain instruments to

In this experiment‚ there seem to be a balance of crickets on each side of the chamber. This show that overtime the crickets will adapt to their environment or the cinnamon has no effect on the crickets at all. This makes sense because crickets are not usually exposed to cinnamon; therefore the cinnamon’s odor should not have a major influence on the crickets’ behavior. This experiment did not account for other species of insect‚ which mean that in some species it may cause a strong interaction between

Experimental Design The researchers utilized two different experiments with multiple parts in order to obtain the data needed to provide conclusive results. The first part involved a lottery from 10 different choices. Participants would choose between option A and option B for 10 different times‚ which would represent

The purpose of the quantum laboratory is to allow students to explore and better understand the foundational experiments that led to the development of quantum mechanics. In general‚ the laboratory consists of an optics table where a source‚ sample‚ modifier‚ and detector combination can be placed to perform different experiments. These devices are located in the stockroom. You can gain access to the help menu‚ for the quantum lab‚ by clicking on the bell in the stockroom
