Experiment 1: Error‚ Uncertainties and Measurements Laboratory Report Jan Luke Mendoza‚ Alexis Vienne Munar‚ Paula Murakami‚ Giorla Joanne Negre Department of Math and Physics College of Science‚ University of Santo Tomas Espana‚ Manila Abstract Throughout the experiment the main goal is to find out about the realities in taking measurements‚ that is‚ that there will always be an uncertainty for each acquired value. And to find out and recognize these uncertainties was handled in the

My experiment was to find out how the type of liquid can affect the amount of drops that can fit on a penny. I used 3 liquids to test my question and they were water‚ rubbing alcohol‚ and vegetable oil. I discovered that water could hold the most drops and vegetable oil and rubbing alcohol could hold about the same amount of drops. My hypothesis was if I use water then it will hold more drops than vegetable oil. My hypothesis was supported by my data. The average number of drops for water was 93

This will allow it to absorb some carbon dioxide from the atmosphere and lower its pH from a level of about 7 to about 5.8. The distilled water will act as a model for "normal" rainwater‚ which has a pH of about

Introduction In my experiment I will be testing the differences of wood being soaked in rain and saltwater for a period of days. Then set out to dry to see if it had any change in width and weight. Question Does water affect the weight and appearance of wood over periods of time? Hypothesis I believe Red Oak will have the most change in weight in saltwater and the most change in appearance will be Pine in saltwater. Materials 1/3 8ft of Red oak 1/3 8ft of Yellow Pine 1/3 8ft of Treated

Lab Report: Hard Water Purpose: The purpose of this lab is to determine whether a liquid is hard water or not. Background: Hard water is the water that has a high amount of mineral in it‚ usually Ca2+ and Mg+. These cations enter the source of water by leaching from minerals within a wet underground layer of water- bearing rock‚ or an aquifer. According to the WHO‚ hard water is not harmful to human’s health but it’s a serious problem in the water industry. Household plumbing and appliances

voltages. The main question of the experiment is “how long will someone continue to give shocks to another person if they are told to do so‚ even if they thought they could be seriously hurt?” (Milgram Experiment‚ 2008). Of course to conduct any experiment‚ you need participants. Stanley Milgram had forty subjects which were all males. According to Milgram they were “recruited via mail and a newspaper ad. They thought they were going to participate in an experiment about ‘memory and learning’” (2008)

What my project is about: I will be comparing results from water testing I did at two different water bodies to prove that the catchment area has an influence over the water quality in the different water bodies. The first water body I tested was the small dam in the bokkie park situated in between residential areas and in the middle of a piece of land solely used for animals. The second water body I tested was the small dam across the road from the Trinity Church in Boksburg on Rondebult Road‚ which

Hannah Herbert BioL121 9/16/14 Density and Making Solutions Objective and Background/ Theory of Experiment: The objective of the experiment was to determine the density of a metal along with the density of distilled water. In an attempt to help the experimenters more thoroughly understand the relationship between concentration and density. Archimedes a Greek mathematician in the third century B.C. originally determined the relationship between the amount of matter that is within a particular space

Environmental Stimuli on Animal Behavior AP Biology Emily Olsen April 26‚ 2012 I. Introduction: The purpose of this lab is to test the effect certain stimuli has on the behavior of a terrestrial isopod. These bugs are more commonly known as pill bugs and potato bugs. The objective of this experiment is to determine which kinds of habitats potato bugs favor. Potato bugs have an innate behavior called taxis which will cause the animal to move away from a stimulus that is unwanted and towards a
