The human cardiovascular system consists of the heart‚ the blood‚ and a system of transporting vessels. A human heart has four chambers: a right and left atrium and a right and left ventricle. The fist-sized heart sits in its own sac (the pericardium) in the middle of the chest under the sternum. In most people‚ the apex of the heart points to the left. There are two circuits of simultaneous blood flow in humans: a pulmonary circuit and a systemic circuit. In the pulmonary circuit‚ the right

Hoeung 1 Tiffany Hoeung Ms. Braceras Honors Earth Science 4 March 2015 How Does Slope Affect the Movement of a Glacier Purpose: The purpose of this lab was to find how slope would affect glacier’s movement‚ and whether the movement was at a constant rate or changed. Hypothesis: If the slope is more steep‚ then the glacier’s movements will be faster than a less steep slope. Materials: Flubber Glue Water Borax Long tray Timer Procedure: 1

Enzyme activity The introduction is a statement of the subject and objectives of the experiment and presents your hypothesis. Relevant background information (appropriately referenced) is given in sufficient detail that a person unfamiliar with the topic can understand the nature of the experiment. A good introduction is clear and concise. Carbohydrates and proteins should be explained in terms of their structure and major functions in cells. Your intro should end with a brief overview of the amylase

9/23/12 Lab Report #1 Meter Reading Summary The objective of this experiment was to learn how to read different meters like the D.C. volt meter and the D.C. amperes meter. In all meters each big line is a major division and each little line in between is a minor division‚ and if there is a line smaller than the minor division lines then that would be a sub minor division. Each meter has a low‚ medium‚ and high range. For example on the D.C. volt meter the ranges go from top to bottom 150‚ 15‚

Engineering B45 Concrete Lab Report Introduction: Concrete is a mixture of sand and rock or similar inert material (aggregates) held together by a cementing material. Usually the cementing material is Portland cement‚ but sometimes binders such as asphalt or gypsum are used‚ in which case the concrete may be called asphaltic concrete or gypsum concrete. Properties of concrete are governed not only by the properties of its ingredients (cement‚ water‚ sand‚ and coarse aggregate) but also‚ to a great

Crystallization: Lab Report Theory/Introduction The purpose of this lab is to understand the concept of purification through crystallization. Crystallization is the process of purifying a substance‚ with the most adequate solvent. The process of crystallization came to be based on the principle of solubility. First‚ we must choose a solvent. The solvent is crucial to crystallization because it’s what will allow impurities to dissolve. Therefore‚ when selecting a solvent it is important that it

CO2 Lab Report Intro Alka-Seltzer tablets are used to treat cold/flu symptoms as it produces CO2 when dissolved in water. The goal of this lab is to calculate the amount of NaHCO3 is needed to produce enough CO2 gas to fill the room. Experimental One Alka-Seltzer tablet was weighed on the analytical balance. Then a piece was measured out to be between 0.21 and 0.28 grams. 500mL of distilled water was added to a 600mL beaker. 80mL of water was mixed with 20mL of 6M HCl in a 150mL beaker. A
