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

Measurement of the distance‚ the thickness and the radius of curvature Purpose : To learn how to use vernier caliper‚ micrometer and spherometer to measure internal and external diameters of a pipe‚the thickness of a copper rods‚ and the radius of curvature of spherical lenses. 1) Vernier caliper: As shown in Fig. 1 the main fixed scale in the vernier caliper has 1 mm gradations while th sliding scale (vernier scale) has 0.05 mm gradations. The smallest division of vernier scale is called

variable represents the length of the string and the dependent variable represents the period of one oscillation. The control variable is the mass of the pendulum. In this lab our goal was to see if we can prove if the acceleration due to gravity is 9.8m/s2. The R2 in this lab is closed to 9.8 m/s2 . The formula that we used in this lab is T=2πLg and then we solved for g=L(T2π)2. HYPOTHESIS: The gravity will be 9.81 m/s2 at sea level due to the acceleration. PROCEDURE: Materials: stopwatch‚ meter
