Name Lab‚ Week #1 BALANCE LAB Introduction Several instruments are used for determining the mass of a chemical; these instruments are called “balances.” However‚ different balances have different measurements‚ meaning that some balances are more accurate than others. Moreover‚ there are several techniques that are used or practiced in order to obtain an accurate measurement. The two techniques are direct weighing and weighing by difference. Direct weighing simply means to read the mass

One of the main learning experiences of this lab is to learn the importance of calibrating a sensor. In most cases‚ a sensor will not have an output that is exactly what you need. An example of this is a strain gage. A stain gage gives back a voltage‚ but with that given voltage a distance can be found. Introduction: In this experiment‚ the QNET-MECHKIT was used. This board has multiple compact sensors that can be used for experiments. For this lab we will be using the strain gage to find the

understand the photosynthetic process to help enhance the efficiency and quality of life on Earth. By fully understanding the function of photosynthesis‚ some environmental adjustments can then be made to refine the photosynthetic process. In this lab specifically (Lab No. 7)‚ we isolated specific color wavelengths and recorded the rate of photosynthesis in comparison to the unaltered rate of photosynthesis

Electrostatic Lab What materials will you use? I will use the virtual lab and elements provided by the class What would you measure? I will measure the static electricity with a neutrally charged balloon What results do you expect? I expect that the balloons charges and sticks to the wall. What is the result are different? That would mean that there is a different way to charge the balloons than negative charge as using your hair. EXPERIMENT Bring together the balloons but not touching

original state and the percent of the hydrate recovered was calculated by using the mass of the rehydrated sample by the mass of the original hydrate and then multiplied by 100%. Data Presentation & Analysis Table 1: The data was collected from the lab experiment. Sample calculations are shown. Mass of beaker with sample 30.765g Mass of empty beaker 30.263g Mass of sample .502g Mass of beaker with sample after 1st heat 30.661g Mass of beaker with sample after 2nd heat 30.657g Heating mass

Lab Report Problem: What method would consistently test the foam and ensure it has the correct density? Background: There are words that need to be understood before executing the experiment. The first thing you need to know is density. Density is a measure of mass per unit of volume. The reason for testing density of doors because doors must contain a density of 14.34lbs per ft3 of foam‚ or it will collapse if the density is too high. If the density is too low‚ it won’t allow for normal expansion

Introduction to Microscale Laboratory Niki Gharavi *‚ Minh Nguyen San Jose City College ABSTRACT: The objective of the experiment was to be introduced to working with the lab equipment‚ specifically heating and measuring‚ and to be able to create some of the apparatus that future experiments will require. Heating methods used were an aluminum block‚ a sand bath‚ and a water bath. The aluminum block heated most quickly while the others were more stable. Regarding the measurement of water‚ the less
