Measurement Systems and Ruler Techniques

Mr. Shallot introduces measurement concepts, focusing on the metric and US standard systems. The video covers the basics of using rulers, understanding significant digits, and handling measurement uncertainty. Practical exercises are included to reinforce learning, with a focus on both metric and fractional measurements.
