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

Microscope lab report Introduction Microscope is a tool used to enlarge images of small objects that are hard to study with bare eyes. The compound light microscope‚ which is going to be used in this lab activity‚ is an instrument with two lenses and various knobs to focus the image. In this lab‚ we will learn about the proper use and handling of the microscope. Objectives: •Demonstrate the appropriate procedures used while using the compound light microscope correctly. •Make and use a wet mount

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

Magnesium is one of the twenty-four elements on earth that are essential for life. It is vital in human metabolism; and if our magnesium levels are too high or too low‚ we could suffer from sleep disturbances. Magnesium is a very common element found on earth that is used for a lot of everyday items. Much of what we have today would not be possible without magnesium. Magnesium was originally discovered by Sir Humphry Davy in 1808‚ but some are not sure if he officially isolated the element. It was
