Introduction In my report I will discuss what I did as an experiment and what I hope for it to achieve. Firstly I carried out an experiment to assay the effectiveness that a range of disinfectants have on the growth of ecoli and whether or not it can prevent it from growing. From the experiment i should be able to see that some disinfectants have a greater effect than others do. From this I shall then draw a conclusion and evaluation on what was the most effective‚ and could there have been any

The reason for the experiment is to see which color from the light spectrum causes plants to grow faster. The prediction was that read light would cause the most growth in plants and that blue light would result in slower growth. The results did not support the hypothesis. Referring to table‚ one can see that blue caused both the spinach and radish plant to grow the most and that green light cause the plants to grow less. Spinach is a long-day plant therefore it was able to grow better under a constant

Physics 1003 Experiment Report In this experiment‚ the technician began with the demonstration of solar energy. Solar energy is the conversion of light energy to electrical energy by using solar panels. Solar panels are devices that contained solar module which use light energy from light to generate electricity through the photovoltaic effect. And photovoltaic modules generate electricity from a frequency of light. From my observation of the experiment‚ I found that the panel is black in

level. The objective of this experiment is to study the characteristic of four different types of membrane. The membranes used in this experiment are polyamide film ( AFC 99 ) as membrane one ‚ polyamide film ( AFC 40 ) as membrane two ‚ cellulose acetate (CA 202 ) as the third membrane and PVDF (FP 100 ) that act as the fourth membrane. In order to identify the characteristic of all four membranes‚ experimental procedures should be done. The variable for this experiment is the membrane maximum inlet

Design of Experiments (DOE) Tutorial Design of Experiments (DOE) techniques enables designers to determine simultaneously the individual and interactive effects of many factors that could affect the output results in any design. DOE also provides a full insight of interaction between design elements; therefore‚ it helps turn any standard design into a robust one. Simply put‚ DOE helps to pin point the sensitive parts and sensitive areas in designs that cause problems in Yield. Designers are then

Helicopter Experiment Prediction: As the mass on the helicopter’s copters increases‚ the speed taken for the rotors to spin down faster‚ this is because there will be more downward pull from gravity‚ as the terminal velocity for a paper helicopter is low. Variables: Independent variable will be the mass that we change throughout the experiment. The dependant variable will be the time that we measure for the helicopter to reach the floor. Finally the controlled variables include‚ the helicopter

where I divided its mass by its density to get its final volume so that I can create the perfect submarine for the experiment; final density of the submarine‚ where I added up all of the mass of balloon‚ pellets‚ and rubber band and divided by the volume of sphere so that I get the final density of my submarine and test if my submarine flow appropriately. The lab experiment on the identity of the unknown metals went well except that I have made a little bit of error on my calculation of the

Unconciously however‚ that must be no mistake‚ seeing that Water will be the theme of the experiment I will be working with. I’m still a little skeptical as to how I chose Water . There was no real inspiration‚ or interest on such force but rather an intuition that drove me to further explore this element. Perhaps an unconscious inclination

float. Any object with density more than that will sink. Carbon dioxide‚ or CO2‚ also played a big role in this experiment. Many soft drinks contain CO2. Studies show that Sierra Mist had the most carbonation out of most soft drinks. There was a lot of carbon dioxide in the soda. That was the reason the raisins would float up and down. There were many purposes to this experiment. One purpose was to teach us about density when we saw how the raisins floated to
