Fuels Investigation Aim: To find out which fuel gives out the most energy. Planning We will be using 6 different fuels to heat up 100ml of water‚ and find out the changes of the temperature. We will measure the temperatures of the water before and after the experiment. We will burn heat the water for exactly 2 minutes‚ and check the changes in temperature. The change in temperature will allow us to work out the energy given off the fuel by using this formula: Mass of water x 4.2 (water’s specific

Abstract: The purpose of this lab experiment was to discover genetically modified organisms. We analyzed our results and found that our sample was GMO positive. These results were attained through polymerase chain reaction and agarose gel electrophoresis. We came to the conclusion that the presence of a band in lane 4 confirms that there are indeed genetically modified organisms. Introduction: Overall‚ the main purpose of this experiment was to conduct gel electrophoresis combined with PCR in

Title Testing Kool-Aid Mix for Food Dye Additives Purpose What food dye additives go into the food products we consume and how do these additives affect our perception of that food? Hypothesis If “Black Cherry” flavored Kool-Aid Mix appears red‚ then it will contain the food dye additive Red-40 that emits a red pigment. Background Food color not only affects the appearance of food‚ it also affects our perception of how food tastes. Tests have shown that consumers will choose colored drinks over

demonstrated that the color of a given food dye depended on which light was transmitted in the visible spectrum and which light was absorbed. A quantitative measurement of the absorbance spectrum of each food dye was obtained through spectrophotometry.1 Through this method‚ we determined that the wavelength of maximum absorbance of a given food dye was directly correlated to the color of that food dye. Further‚ darker food dyes absorbed more light than lighter food dyes (Table 1). The relationship between

ups Identifying food groups in unknown solutions Aim The aim of this experiment is to identify different food groups within several different unknown solutions. This will be carried out by placing the unknown solutions into separate test tubes and using different chemical indicators to see if any reactions occur. Each food group will act different when the chemical indicator is added‚ some will change colour while others will separate. Introduction Food is a vital source of energy that is

Techniques and Measurements Lab 1 The purpose of this lab was for the student to get involved with his or hers new lab kit as well as being able to know‚ identify and use each other tools provided in the kit. Another key learning aspect of this lab is to teach the student how to measure properly the many units in the SI system. I will be using laboratory dilutions‚ measurements‚ and weights to then calculate using algebraic formula. Throughout lab one we were introduced to many different

This lab report will be detailing the steps taken and the results discovered when using spectrophotometry to determine the percentage of copper in a copper-clad penny and the thicknes of the copper layer on the copper-clad penny. After 1982‚ copper coating has been used in the creation of the penny because the cost of pure copper has increase to the point that the amount needed t omake a penny cost far more than the actual value of the penny. This lab allowed us to see just how much copper coating
