Measurement of Mass

Koki Christopher Titewondze goes over the corrections of the prior assignment and introduces today's topic of mass measurement, providing a plan of the day's lesson. He covers identifying the accurate measurement method for rulers used together, defining the objectives, prerequisites, and activities. The lesson covers the instruments used for the measuring of mass (extension balance, compression spring balance) before covering the definition and units of mass, and the definition, description and correct uses of a triple beam balance for measurement. At 8:15 there is the actual lesson as he defines mass. He includes an exercise for the viewer to determine how the principles discussed are used, before finishing the lesson.
