Scientific Measurement Tools and Concepts

Mr. Baldwin introduces the metric system and measurement, covering mass, weight, length, volume, temperature, and time. He explains the differences between mass and weight, how to measure length using meters, and volume using liters or cubic centimeters. Temperature is measured in degrees Celsius, and time is measured using a stopwatch. The video concludes with a review of learning objectives and encourages students to ask questions.

What is the primary objective of the lesson on the metric system?

• To learn about the history of the metric system

• To identify tools and units for scientific measurements

• To convert between metric and imperial units

• To memorize metric system prefixes

How is mass different from weight?

• Weight is measured in grams, mass in pounds

• Mass is constant, weight changes with gravity

• Weight is the amount of matter, mass is the gravitational pull

• Mass changes with location, weight does not
