How high is the water conductivity level of the water sources in Goa Gajah? I predict the level of electrical conductivity of the water sources in Goa Gajah will be between the range of a normal drinking water, which is 0. 0005 to 0. 005 s/m. This hypothesis is based on the fact that conductivity […]

Widespread freshwater pollution affects all areas without exception. Although residing in rural communities is enjoyable, examining the reality of nonpoint surface runoff from river bottom farm lands, manufacturing companies, and rock quarries reveals hidden issues. To sustain cleaner fresh water in our lakes, streams, and rivers, my strategy involves educating the community. My plan begins […]

Conductivity Solutions Abstract: We produced conductivity tests in water and other various solutions with a computer faced Conductivity Probe using the unit of microsiemens per centimeter (uS/cm) to find out which solutions had a high conductivity and which solutions had a low conductivity. Many different solutions vary in conductivity due to the ratio of ions. […]

Introduction: This lab helps further our understanding of essential principles behind diffusion and osmosis. Permeability, concentration gradients, plasmolysis, water potential, and equilibrium were also concepts that were delved into in this lab. Understanding how diffusion and osmosis works is essential to understanding biology. Each time a cell has something move into or out of it, […]

When I began to write this paper, a lot of events came to mind. One event that stands out is the family vacation I took to Toronto, Canada. It took place in middle of the hot month of July in 2007. It was a family trip that I went on with my church, Brown Missionary […]

Effect of caffeine on Daphnia (Water fleas) Introduction- In this study I am going to investigate the effect of caffeine on Daphnia (water fleas) heart rate. I shall use daphnia as they would never have been exposed to caffeine before, unlike a human, who may have already developed a high tolerance to it. Another reason […]

In the beginning of the month, FMN Can Food Company had announced that there will be a large sized factory built for the company’s can manufacturing near our community. People in the community had shown their concern and attention to this matter. Some supported the project while others tried to oppose it. After conducting researches […]

Aim: To react NaHCO3 with HCl to form NaCl and two other products and then calculate the mole relationships between NaHCO3 and NaCl and calculate a balanced equation for this reaction. Safety: •Wear safety goggles at all time •Handle all chemicals with care •Use equipment like tongs when handling warm/hot objects •If chemicals are spilt […]

The Chemistry of Natural Waters Introduction: Four different taps will be used to collect water samples. The first is located in the West Residence Halls at Hamilton Hall while the second is located in the East Residence Halls at Bigler Hall. The third water sample will be collected from University Towers situated on College Avenue […]

Purpose: The pupose of this lab was to make an experimental determination of a molar volume through reaction of the substance shown: Mg(s) + 2HCl(aq) > MgCl(aq) + H(g) Introduction: In this lab, a magnesium ribbon and HCl are combined in a gas measuring tube. When they are combined they form magnesium chloride and Hydrogen […]

I am going to do an experiment to test how much sugar can be dissolved in different volumes of water. I will measure different volumes of water out and then add a certain amount of sugar to it and stir it until it dissolves fully, I will keep adding more and more sugar until the […]

Hydrated FeSO4 can come in many hydrated forms. Using two methods for better accuracy and to make a comparison, I will deduce the number of water molecules per mole of a hydrated iron sulphate sample. Method 1: FeSO4. nH2O(s) ½ FeSO4(s) + nH2O(l) =dehydrating the FeSO4 by evaporating the water and calculating the mass lost. […]

The objective of the experiment is to determine the effectiveness of air as an insulator. There are three types of heat transfer: Conduction, Convection, and Radiation. Conduction is particularly common in metals, where increasing temperature causes ions to vibrate and gain kinetic energy. This energy then transfers to cooler parts of the metal where free […]

Leaves are made up of several different layers of cells, which are very complex. They all have different functions. Leaves differ from one plant to another. Some may be very large, while some may be small. There could also be a difference in texture, colour and shape. Some leaves may also appear more turgid, while […]

I intend to determine the optimal rate of anaerobic respiration in yeast through an experiment involving heating the yeast within a glucose solution. The heating process triggers the release of gas, which I will measure as my experimental data. To ensure safety, I will wear protective goggles throughout the experiment. Additionally, I will utilize a […]

One dicotelydonous leaf was taken and approximately 1cm� of clear nail varnish was painted both on the adaxil (top) and abaxil (bottom) surfaces of the leaf. It was then left for approximately 10 minutes to dry and gently peeled off using a scalpel after the 10 minutes. The peeled nail varnish was then examined first […]

This investigation is looking at three water samples A, B, and C, which have been associated with a gastrointestinal infection of children in a small village. In which three walls have been associated with the path of infection. The likely cause of outbreak has been identified by using a serial dilution of the samples, which […]

There are several factors that affect the corrosion rate of marble buildings due to acid rain. These factors include temperature, concentration, pressure, surface area, and occasionally light. To better comprehend how acid rain corrodes marble, we conducted a study on the corrosion rate of marble chips using Hydrochloric acid. It is crucial to understand that […]

I spent my childhood surrounded by a beautiful natural landscape of white sand beaches, turquoise water and tropical jungle with a large variety of wildlife. In kindergarten I assisted to a Interiors school which promoted the moral values of humanity. Afterwards I attended a Waldron school which had great emphasis on arts and the development […]

One Queen’s life, however, can be accounted for. Her name is Queen Alfred. The life of Queen Alfred was greatly affected by the geography, science, technology, time continuity, and culture of the Anglo Saxon collocation. Queen Alfred (otherwise known as Alfred or Lifestyle) was the first kings’ wife ever to be anointed queen of England. […]

During the experiment there were some mistakes in the data cause of human error. Scientists accidentally spilled the hydrated copper sulfate after the second measurement though It lost 0. 07 g when It was only supposed to As is explained in question two below, when not all of the water is driven off there is […]

The International Energy Agency’s 2008 report predicts that within the next 15-17 years, more than half of the world’s population will reside in urban areas. The environment suffers from the negative consequences of urbanization, including air pollution that harms crops, forests, animals, and water sources. Urbanization also leads to ozone layer depletion and negatively affects […]
