Lab One: Laboratory Techniques and Measurements
Abstract
The Lab One was done on Laboratory Techniques and Measurements. The first experiment with my Lab partner; we got opportunity to experiment how to conduct measurements in length by using metric conversion. We started in cm units and changed into mm by x10, and moving decimal point x1 to right. To find in meter we moved from cm to meter two decimal points to the left or double check our self divided by 100 and all records in data table 1. The second experiment was to measure temperature of how cold and hot tap water can be by using thermometer in Celsius units. From this experiment, gained knowledge that tab water doesn’t boil to 100 Celsius related to containing different elements and salts it boiled up to 74 Celsius in five minutes of boiling. Our understanding that only pure water boils up to 100 Celsius. Also, the longer it boils the higher the increase temperature and evaporation occurs; this recorder under data 2. The third we were able to conduct Volume of how much drops and volume of water can hold thin-stemmed pipet, this recorded under data 3. Then we moved to data 4 for mass measurement, it was estimating 7 objects by holding to objects, and obtaining actual mass using a digital scale and recorded in grams. The last few objects, we got closer with estimated mass to actual mass do to more experiments. The data 5 able to get knowledge of density by using digital scale and common products salt and isopropyl alcohol; we gain from this experiment, that more saturated solution the higher it mass. After we used irregular objects metal bolt and magnet to find a density and used displacement method, it recorded under data 6; by using the formula density equal to the mass of its volume. The 7th data using Archimedes’ Method, noted that using irregular objects by dropping them in water we got greater volume results then displacement water, also the tie of a string gives more mass to object.
