Basic Lab Measurements and Equipment Purpose This lab experiment displays the accuracy of scientific measuring equipment. This experiment also helps to familiarize the students with these instruments. Procedure: Measure Volumes and Masses 1. Obtain a 400mL beaker and record its mass in grams. 2. Add 40mL of water to the beaker and record the volume. 3. Records the beaker’s mass now with the added water 4. Transfer the water from the beaker to a 50mL graduated cylinder and record the measurement

It would be normal to think that immigrants and refugees will affect somehow the economy of the European nations‚ because more jobs and health coverage is required‚ but also more goods will be needed in order to meet a higher demand. Prices might increase‚ but it is important to be mindful that companies that sell inferior products might increase in revenues since refugees will be able to spend only a few euros on their goods. According to Huttl P. and Leandro A. (2015)‚ “ the net fiscal contributions

Lab Report 1: Measurement Lab Date: January 17‚20XX Lab Partners: XZ Report Date: January 24‚2014 Report Written by: XXXXXX Introduction: Measurement is a form of quantitative observation. The ability to make accurate and precise quantitative observations is crucial to science. Accuracy in this sense refers to the closeness of the measured result to the hypothetical “true” value (Motzny 2014). Having a precise measurement implies its exactness.

Refractive index measurement is actually a measurement of the speed of light in a medium. The speed of light (usually denoted by c) is 299 792 458 m/s in vacuum. In other media the speed of light is lower than this value‚ and the refractive index‚ R.I.‚ of a medium is a measure of how much the speed of light is reduced in the medium. The refractive index (n) of a medium is defined as the ratio of speed of light in vacuum (c) in to that in the medium (v) The speed of light in a medium depends on
