Energy use is one of the most important issues in the world today. People are starting to run out of energy already now, and in the future more and more energy is likely to be increasingly needed since the world population is growing. Fossil fuels are the main resources for …

I. ROCKSTAR, INC. Rockstar Energy Drink was founded by Russell Goldencloud Weiner, a doctor of nutritional enthomedicine, according to the Rockstar website. His parents, two renowned herbalists, helped to produce the Rockstar formulations. Today, three formulas of Rockstar are on the market: Original, Cola, and Diet. The original formula was …

Introduction: The rate of photosynthesis varies greatly with changes in wavelengths of light. Light’s colour is determined by its wavelength of light, and thus it is possible to devise an experiment to determine which wavelengths of light are most productive for photosynthesis than others. In this experiment I use a …

1. Label 7 of the dishes with the names of the following products: Sulfur, Iron, Sodium Bicarbonate, Sodium Chloride, Sugar, Sand, and Magnesium. Place small samples of each in the appropriate dishes. 2. Examine each sample with a magnifying glass and magnet and record your observations in the data table. 3. …

In my coursework I will investigate about enzymes in potatoes reacting with Hydrogen Peroxide. In particular I will investigate the effects of changing the surface area of a potato when added to Hydrogen Peroxide. This is because, when increasing the surface area of the potatoes it will increase the rate …

Aim: To investigate the factors of affecting the resistance of a wire. In this experiment I will be using a metal nichrome wire to show the resistance when the length and width is changed. Variables Variables that I am going to keep the same. Variables that I am going to …

Why will insulators affect how long a test tube of hot water stays hot? Background Information I know that there are many different ways of insulating this test tube, shiny foil can be used because it’s a poor emitter of radiation and it will reflect escaping heat by reflecting, because …

1.0 INTRODUCTION Flame photometry, also referred to as ‘flame atomic emission spectrometry’ is a quick, economical and simple way of detecting traces of metal ions, primarily Sodium, Potassium, Lithium, Calcium, and Barium, in a concentrated solution. The process is an extension of the principles used in a flame test, with …

For this lab the rate of photosynthesis was analyzed upon plant leaves. A sample of a light exposed and a not-light exposed leave were used to clearly identify the role of sunlight in the process of producing and storing energy. Aim We are trying to find proof, to demonstrate the …

Do you feel that your academic record (I.e. grades, course load, etc.) is an accurate reflection of your ability and potential? In comparison to your college friends and classmates, do you feel that you were particularly advantaged or disadvantaged? Although my recent academic performance is excellent, I wasn’t always able …
