Introduction The experiment was all based off of the question does the amount of candles affect how high the water rises? The hypothesis was also tested by the experiment‚ and this was the hypothesis‚ the amount of candles affects the height of the water. This hypothesis was chosen because it was known that the more candles lit in the container it used more oxygen and without the oxygen the contained created a vacuum that brings up the water‚ and that the more candles the stronger the vacuum.

An independent variable is a factor that is changed throughout the experiment to determine the results. In this case‚ the independent variable were the types of cleaner used (Palmolive‚ Betadine‚ Dettol). These were changed throughout the experiment to compare different effects of cleaners towards bacterial growth. A dependent variable is the factor in which is being measured and observed. In this case‚ the zone of inhibition was measured which was used to determine the area and percentage of the

SETTLEMENT OF PURE KAOLINITE CLAY BY USING OEDOMETER IN 1-DIMENSIONAL CONSOLIDATION Abstract The aim of this experiment was to explain how to use two type of oedometer to calculate compression index (Cc) and re-compression index (Cr)‚ measuring the pre-consilidation (s’vc)‚ and to predict the coefficient of consolidation (Cv). The soil used in this experiment is Kaolinite clay‚ which has Cv = 8.69 sqm/year at 300 kPa (hydraulic result) and Cv = 2.98 sqm/year at 288 kPa (manual result)

diffusion. The water in each experiment measured 13 cm from the bottom of the glass to the top. The tap water for each experiment was taken from a jug so the temperature would be consistent. Before the food coloring was added the water in the glass was allowed to settle to decrease any movement. In the first experiment it took 61 seconds for the drop of food coloring to reach the bottom of the glass‚ in the second experiment it took 51 seconds and in the third experiment it took 32 seconds.

example‚ I am now studying science so I need to do many experiments. An experiment contains many complicated steps. Only a minor mistake will result in the failure of whole experiment. Therefore‚ I communicate with my group-mates and divide the experiments into different parts. Each group-mate is responsible for a part of it. We help each other during experiments. Because of the cooperation and communication of group-mates‚ the experiments can be completely successful. Moreover‚ I am a trumpeter

conducted the experiment with termites in order to determine how they react to pheromones present in different colors of ballpoint pen ink. The experiment consisted of two parts: in first part we used a ballpoint pen with blue ink‚ in second – a ballpoint pen with red ink. The reaction of termites was measured by their performance in 1 minute. Every termite in experimental group went through 3 tries in each part of the experiment. The results were recorded and analyzed. The experiment showed that the

Motion of the system will be established by an initial disturbance. Furthermore‚ if there is no resistance or damping in the system‚ the oscillatory motion will continue forever with constant amplitude. Such a system is termed undamped. In this experiment the natural frequency for an undamped spring mass system is to be determine by using a mass-spring-damper. THEORY Newton’s 2nd law …………………….………. ( Equation 1 ) Hence‚ ………………….……...

conducting experiments or gathering data. The various processes that scientists go through to find evidence to support their theories (trial and error‚ systematic result collection‚ experimenting with a hypothesis etc.) all add a certain weight to their discoveries about a knowledge claim‚ often strengthening the argument for or against a certain aspect of the claim. One issue that arose while we were examining Human Sciences as areas of knowledge‚ on the other hand‚ was how experiments have a comparatively
