Measuring Mass and Volume Concepts

This video tutorial covers the concepts of mass and volume, focusing on how to measure them accurately. It explains the difference between mass and weight, and provides detailed instructions on using scales and graduated cylinders for measurement. The tutorial also introduces the concept of digital uncertainty and how to estimate it. Practical examples are given for measuring volume, including the use of water displacement for irregular objects.
