the period of oscillations to the length of the pendulum.Sources of error for this procedure included precision in both length and time measurement tools‚ reaction time of the stopwatch holder‚ and the accuracy of the stopwatch with respect to the lab atomic clock. The final result of g takes into account the correction for the error introduced using the approximation. There are opportunities to correct for the effects of mass distribution‚ air buoyancy and damping‚ and string stretching[1]. Our results

# Now You See It – Copper Cycle Lab The purpose of the lab is to discover what happens when someone executes a series of procedures‚ beginning with copper metal. What is done | What is observed | 1. Started with copper‚ Cu (s). | reddish‚ brownish‚ orange-ish‚ powder-like | 2. Added nitric acid‚ HNO3 (aq). | acid turns blue and smells like chlorine. | 3. Added water‚ H2O (l). | stayed the same | 4. Added sodium hydroxide‚ NaOH (aq). | changed consistency‚ gel-like | 5. Heated the

Shape: The skeletal system gives the human body structure. It supports the internal organs that are held within the body in a network of tissue. Bones give us form. In sports support and shape are also used for example in a rugby scum‚ to body needs to be placed in such a way to keep the back aligned. Movement/ Attachment: The skeleton is jointed to allow movement. A joint is an articulation of two or more connecting bones‚ providing us with either stability or movement. Muscles are attached

Purpose: To observe epithelial tissue by using a microscope to compare prepared slides. Introduction: Epithelial tissue covers the whole surface of the body. It is made up of cells closely packed and ranged in one or more layers. This tissue is specialized to form the covering or lining of all internal and external body surfaces. Epithelial tissue can be divided into two groups depending on the number of layers of which it is composes. Epithelial tissue which is only one cell thick is known as

the lungs to the left side of the heart is pumped to the body’s cells (the systemic circuit) for gas exchange. The deoxygenated blood is returned to the right side of the heart. Strenuous exercise causes a dramatic increase in blood flow to skeletal muscles that depend on the red blood cells to bring them the oxygen necessary for cellular respiration ‚ which is the quantity of blood pumped from one’s heart and clinically measured per minute. There are several points in the body where the heart

Wave Nature of Light Objective: The purpose of this lab is to investigate interference‚ otherwise known as the diffraction of light. A beam of light acts a wave‚ and we are able to use equations so calculate the wavelength of the light used. The diffraction of a straight edge demonstrates that light waves bend around straight edges‚ allowing light to enter an area of shadow. When waves are superposed‚ they reinforce each other when crests are in phase and cancel out when they are not in phase

Laboratory Report The Plasma Membrane I. Introduction The Plasma membrane is the edge of life‚ the boundary that separates the cell from its surroundings. It controls the traffic of materials in and out of the cell. (Reece‚ 2011). It is incredibly thin that is very vital in maintaining the integrity of the cell. Not only does the plasma membrane bind the other organelles‚ it also forms a dynamic structure which gives them their remarkable activity and selectivity. (Hickman‚ 2008). Diffusion

LSM1102 Lab Report Introduction Transformation is a process which involves plasmid DNA being bound to the cell surface and the subsequent uptake of DNA by the cell (Panja et al.‚ 2008). For artificial transformation of E. coli cells with plasmids‚ plasmid DNA has to be extracted from bacterial cells using the High-Speed Plasmid Mini Kit‚ which is then mixed with competent E. coli cells followed by heat shock and the streaking of transformed cells on two different types of agar plate (LB and LB+ampicillin)

Anatomy & Physiology I Cranial Nerve Lab Report: Zoe’s Case Annastelle L. Cohen‚ Brandi Brown‚ Mariann Killen Howard Community College BIOL-203: Anatomy & Physiology I Professor Canham April 26‚ 2016 Introduction There are twelve pairs of cranial nerves associated with the human brain that all have individual and essential functions. They are represented by a name that is followed by a Roman numeral. The cranial nerves are organized in a cranial to caudal sequence (Howard Community
