Date of Experiment October 7‚ 2012 Report Submitted: October 7‚ 2012 Title: Liquids and Solids Purpose: The purpose of this experiment is to determine the boiling point of liquids and the melting point of solids. Procedure: I got all of my materials together and set up. I poured rubbing alcohol in a beaker and rubber banded it with the thermometer. I logged the last bubble that came out of the capillary tubes. After that I crushed the acetamide and carefully put it in the capillary tube

Effect of Sugar on Bean Plant Growth Abstract The objective: My project was to determine if bean plants grew stronger and healthier by the addition of the right amount of sugar to their watering. I believe that plants that receive 50 grams of sugar per liter of water would help bean plants grow to be stronger‚ healthier and larger because they would get energy from the sugar. Methods/Materials 36 bean plants were grown in potting soil. The same amount of soil was used in each pot and it had no added

The effect of enzyme concentration‚ substrate concentration‚ pH‚ and temperature on the enzyme catalase. Introduction: Enzymes are biological catalysts; proteins and RNA. They are required for most biological reactions and they are highly specific. Each enzyme has an active site. The active site is the spot on the enzyme where a substrate fits in. Substrates binds with enzymes through the active site. Enzymes‚ being highly specific‚ only fit with one certain substrate. Enzymes and substrates

“Discuss the Causes and Effects of Economic Growth” Economic Growth is where goods and services maximise in value over a period of time. This is measured by Real Gross Domestic Product (GDP) which is defined as “The total market value of all final goods and services produced in a country….equal to the total consumer‚ investment‚ and government spending‚ plus the value of exports minus the value of imports.”(www.Investorwords.com) In turn this is measured by the level of aggregate demand in the

The aim of this experiment is to better understand the process of fermentation of yeast in different concentrations of sucrose. The experiment worked with yeast and sugar (sucrose and glucose) to determine the rate of fermentation by testing the pressure of C02 in the test tube. The experiment tested the metabolic capability of yeast anaerobically meaning no oxygen was present (this was ensured by the thin layer of oil on the top of the solution). This means that the metabolic rate of the yeast could

Concentration The Problem In many colleges over 8% of the students report problems concentrating on their studies. Most of these students blame outside distractions for their problems. Many research studies manipulating noise levels and distractions have found that such disturbances may increase‚ decrease‚ or not even affect concentration. These researchers have therefore concluded that distracters don’t cause concentration problems directly. It is the way the distracters are interpreted

In this essay my main focus is going to be on how advancement in technology has brought about E-cigarettes. I will explain how they function and the kind of damage that they’re causing to human beings causing us to question whether technology is becoming harmful to human beings or not. I will start off by explaining how regular cigarettes work and how they are harmful to the human body causing E-cigarettes

Effects of different liquids on the elasticity of a rubber band Luke lash and Charles baker Question: If we submerge rubber bands in different liquid substances‚ will its elasticity of the rubber bands increase? Hypothesis: If we use a more acidic substance like vinegar‚ then elasticity of the rubber band will increase. Background: We are conducting this experiment because although it has been done before‚ the substances that have been used before are generally ordinary. Others have used hot

Effects of Rapid Population Growth While population growth is at times a beneficial thing for a species‚ there are many factors that define when growth becomes detrimental. When population growth becomes "rapid" there is a great chance that the counter-productive level has been reached. The most accurate index is the balance between population and sustainability. 1. Rapid Growth o Rapid growth is a quick increase in population. The number concerned when calculating the population is the number
