BALANCE LAB Introduction The purpose of this lab is to become familiar with how to use the ChemLab program for determining mass using both the centigram balance and the electronic balance. Using the centigram balance‚ the mass‚ in grams‚ of a copper slug will be determined by both direct weighing and weighing by difference techniques. Using an electronic balance‚ the wight of a copper slug will be determined by also utilizing direct weighing and weighing by difference. Average mass of a

this lab was to a digital oscilloscope to measure various signals. The goal of Part 1 was to measure the mean value‚ the frequency‚ peak to peak voltage‚ and the RMS voltage of a triangular input signal. To meet this goal‚ a function generator was used to generate a 1 kHz triangular wave signal with a 1 V amplitude‚ and the oscilloscope was used to measure the values of that signal. Using the oscilloscope‚ the mean value was found to be -37.6 mV‚ the RMS Voltage was 292 mV‚ the frequency was 1 kHz

Unit 4 Physics Notes Sunday‚ November 3‚ 2013 8:09 PM Any Single disturbance is called a pulse A series of pulses is called a wave In the case of the impatient student‚ his disturbance was parallel to the direction of the wave itself. Also called a Longitudinal Wave WAVES • Waves can transmit two things ○ Can transmit energy Ex. Light waves from the sun heat the earth ○ Can transmit information Ex. Radio wave When the motion of the particles is perpendicular to the motion

1. Diffusion and Osmosis‚ June 4‚ 2013 2. Purpose: The purpose of this lab is to help give visual understanding of diffusion which is a solution of high concentration spontaneously (no energy required) moving to an area of low concentration. Also taking a look at osmosis‚ which is the movement of chemicals across the cell membrane. Osmosis requires some type of energy to be put in for this to happen. After these experiments we should have a better idea and visualization of how chemicals transfer

Kristen Magliola 9/9/13 BIO: 414L Lab Report: SOC Medium I. Purpose: To make liquid and solid media for microbial growth II. Background: There are four different types of media used to grow microbes. They consist of Enriched media‚ Nutrient media‚ Selective media‚ and differential media. Enriched media is a growth media supplemented with complex biological molecules. This type of media is used for blood‚ coagulated blood‚ amino acids‚ etc. Nutrient media provides nutrients necessary
