Lab Techniques and Measurements
Purpose: The purpose of this experiment is for the students to familiarize ourselves with the laboratory tools and techniques. This experiment taught us how to convert between SI units and standard American units of mass, length, temperature, volume and time as well as how to measure the units. Students become proficient lab techniques such as measuring temperature and volume and calculating within them.
Materials: Distilled water, DVD, plastic cup, dimes, fork, ice cubes, alcohol, key, matches, sheet of white paper, pencil, pennies, quarters, spoon, sugar, tap water, 25mL volumetric flask, 100 mL glass beaker, rubber bulb, burner fuel, burner stand, 25 mL cylinder, digital scale, magnet, ruler, pipets, safety goggles, metal bolt, string, thermometer.
