n this lab experiment factors that affected solubility are temperature‚ liquids‚ concentration‚ pressure‚ polarity‚ and molecule. In this experiment we use temperature‚ centrifuge‚ and concentration solutions to be able to achieve the results that we wanted. Step one of the experiment was to mix HCl‚ to cause a precipitation form‚ after that we had to decant the solution‚ then we used a centrifuged to separate the the precipitate of the supernatant liquid. After the decant was done‚ then the process

Watching Iron Jawed Angels really opened my eyes. There was struggle between women and politics‚ but also between women themselves. It was not easy to gain these rights. This was just one step in gaining the equality that women should have. As Alice Paul says in the movie‚ “It’s unfair to die in a fight we shouldn’t have to fight.” In Iron Jawed Angels‚ we are shown part of the journey to gain women the right to vote. Alice Paul and Lucy Burns meet with Carrie Chapman Catt and Anna Shaw about being

We found that the surface area of the block did not change the coefficient of kinetic friction‚ while the types of materialsin contact were directly related to the coefficient of kinetic friction. INTRODUCTION Friction is a part of our everyday life. Nearly every movement we make involves friction‚ and we have instinctively learned to take advantage of friction‚ or the lack

Stacy Hernandez Period 1 Mrs. Riley AP Biology Osmosis and Diffusion Lab I. Introduction: Diffusion is vital to many life functions of a cell‚ it allow the transportation of vitally important nutrients and compounds without the expenditure of excess metabolic energy. To explain diffusion‚ it is as if a bottle of perfume is opened at one end of the room‚ then in a short amount of time a person at the other end of the room can detect the scent of the perfume; this is the process of diffusion

The Iron Coast is a travel writing written by Jane Gardam. Jane Gardam is a British author. She was born in Coatham‚ North Yorkshire. The writing describes the North Yorkshire coast and its landmarks including Roseberry Topping and Cleveland hills. Roseberry Topping is the name of a distinctive hill which was mentioned in the writing. The travel writing is descriptive as it creates effects and atmospheres for the reader. To achieve these effects the author uses a variety of literary techniques such

Flame Test Laboratory Report Introduction The purpose of this lab is to observe and identify metallic ions‚ using flame tests. The traditional flame test originated when Robert Bunsen invented the Bunsen burner to test two new alkali metals he and his partner had discovered. “A flame test is an analytic procedure used in chemistry to detect the presence of certain elements‚ primarily metal ions‚ based on each element’s characteristic emission spectrum” (Flame Test 1). Using this test‚ an element

The experiment was conducted at the Human Kinetics Program (HKP) Building in the University of the Philippines – Baguio. The terrain was prepared by distributing an even layer of gravel on the ground‚ and the background was covered by black cloth spanning the length of the terrain. The subject was also dressed in black to match with the background. The boules‚ jack‚ and significant joints and points on the subject’s body were marked with green bands to contrast with the background. A throwing circle

Combustion Background For this science experiment‚ we will be looking at the differences in calorie count between a food label and and the amount we measure in a lab. For this lab‚ we will be experimentally measuring how many calories are in different types of food. Before we begin the lab however‚ we need to investigate the science behind it. Firstly‚ we need to figure out if this project is even possible. Luna Abdallah et al created an experiment making it possible. To measure the amount of calories

Modeling Effective Dose: Salt Tasting lab Purpose The purpose of this lab is to see at what measurements (of salt) can the salt be detected by taste. Abstract The science of toxicology is based on the principle that there is a relationship between a toxic reaction (the response) and the amount of poison received (the dose). An important assumption in this relationship is that there is almost always a dose below which no response occurs or can be measured. A second assumption is that once a maximum

The Iron Lady is a film‚ directed by Phyllida Lloyd‚ based on the life of Margaret Thatcher‚ the longest serving and the only female Prime Minister of Great Britain in the 20th century. The film shows Margaret Thatcher as an elderly woman who has flashbacks of the major and consequential events of her life. The ghost of her husband Dennis comments and reflects on her successes and failures who really is just the figment of her imagination. Margaret grows up working at the grocery shop‚ that her
