LABORATORY 3 The Effect of Temperature on the Rate of PNPP Hydrolysis Partners: Shelby Cruickshanks Alexis Williamson Introduction Most of the chemical reactions‚ which occur throughout our bodies‚ would proceed at a much slower rate of reaction without the presence of an enzyme. Cells can not wait for centuries for molecules to break down‚ if they waited for that‚ there would be no way for the organism to obtain energy or in turn survive. This is where biological catalyst comes into

be ‘Background music in a supermarket stimulates the consumer’s desire to buy more.’ I am going to conduct this research through using scientific experiment method. The main advantage of this method is its ability to limit alternative explanations and to infer direct causal relationships. I believe it is the best and only way to directly prove a cause and effect relationship between music and how much people buy. In addition‚ this experiment does not take up a lot of time and is not difficult to

EFFECT OF ROOM TEMPERATURE ON THE BURN-RATE OF A CANDLE BURNS Have you ever wondered whether a candle burns more quickly on a hot day‚ than on a cold day? Or is it the other way around? This science fair project was carried out to compare how quickly a candle will burn at different room temperatures. The experiment was done by measuring how much of a candle will melt in 30 minutes when placed in an environment with surrounding temperatures of 20°C‚ 25°C and 30°C. Hypothesis A candle in a colder

Introduction to the Scientific Method The scientific method is the process by which scientists‚ collectively and over time‚ endeavor to construct an accurate (that is‚ reliable‚ consistent and non-arbitrary) representation of the world. Recognizing that personal and cultural beliefs influence both our perceptions and our interpretations of natural phenomena‚ we aim through the use of standard procedures and criteria to minimize those influences when developing a theory. As a famous scientist once

Of course‚ due to the limitations of the procedure‚ they could not be eliminated completely‚ so I will explain what I did to reduce them to an acceptable level and how I could have improved my method to reduce them even further. Equipment justification The following table shows the reasons for my choice of equipment in carrying out my method. Equipment | Justification | 100 cm3 burette | I needed to accurately

SCIENTIFIC REPORT ON THE EFFECT OF WAVELENGTH ON PHOTOSYNTHESIS Red wavelengths will increase the rate of photosynthesis to a greater degree than blue or green wavelengths and thus will be the most optimal for plant growth. This hypothesis will be tested under laboratory conditions using silver beet extracts and DCPIP under different wavelengths and assessing the photosynthetic qualities using a spectrometer at 605nm. Photosynthesis is the process by which the suns visible light (electromagnetic
