Laboratory Measurements and Density Objectives: A. To determine the density of Aluminum (lit. value = 2.7 g/cm3) by determining its mass‚ and measuring its volume by dimensional analysis and water displacement. We will also examine the % error in our determination based on the literature value. B. To determine the mass and diameter of select ball bearing. Plot graphs of mass vs. diameter‚ mass vs. surface area‚ and mass vs. volume. Afterwards use slop of the mass vs. volume graph to determine density

Title Laboratory Techniques and Measurements Purpose The purpose of this experiment is to determine mass‚ length‚ temperature‚ volume‚ and density of objects and liquids using common measuring devices and algebraic formulas. The metric system‚ the most common set of measurements used in science‚ which includes meters‚ liters‚ Celsius‚ and grams will be used. Procedure The following items were used within the experiment: (1) Metric ruler with centimeter (cm) and millimeter (mm)‚ (1)

Reflexes Laboratory Activity (12 points) 1. Amy has numbness of her pinky‚ ring finger‚ and medial surface of her right arm. After neurological testing‚ it is determined that she has a compressed spinal nerve on the right side. a. Which spinal nerve (what level) is affected? The level is C5-T1 cervical nerves. The specific spinal nerve would belong to the brachial plexus‚ the ulnar nerve. b. How did you determine/decide it was this level? The ulnar nerve branches off of the medial cord‚ which is

List of the entire famous scientist Alessandro Volta(1745-1827) An Italian Physicist who was a pioneer in the development of electricity. He created the first electric battery in 1800. This battery gave the world its first continuous‚ reliable source of electric current‚ and led to all important discoveries of the use of electricity. The unit of measuring electromotive force (emf)‚ Volt(v) is named after him. He also proposed the law that the air expands at a constant rate with increasing temperature

ENZYMES LABORATORY REPORT Introduction The utilization of any complex molecule for energy by an organism is dependent on a process called hydrolysis. Hydrolysis breaks complex molecules into simpler molecules using water. Similarly‚ the process that is the reverse of this is called dehydration synthesis‚ which removes water from simpler molecules. However‚ because hydrolysis occurs very slowly‚ living organisms use biochemical’s called enzymes to speed up the reaction. In this lab exercise
