In this video, students learn how to measure the mass of objects using a balance scale. The lesson explains the concept of mass and how it differs for gases, liquids, and solids. It also introduces benchmark weights and different scales...

In this lesson, students will learn how to measure weight in the US customary system of measurement by comparing each unit to everyday objects. They will understand the difference between mass and weight, and how weight can be affected...

Defining the Force of Gravity or Weight and Gravitational Mass. We also determine the dimensions for force in both Metric and English units.

This program begins by discussing common ways mass and volume are measured in the home. The video highlights how mass and volume are measured with various types of equipment in the school science lab. Some of the different tools used to...

Mass is just a fancy sciency word for weight, right? Wrong! Although related, they aren't the same thing. You'd better find out exactly what the difference is so that you don't look foolish around the water cooler!
