The video explains the concept of density, which is the mass of a substance in one cubic meter of it. The equation for calculating density is explained as well as illustrated with a simple example, where a glass block is weighed to find...

In this video, the concept of thermal energy and its relationship with temperature is explained. The specific heat capacity is also introduced and used in calculations to determine the amount of energy required to increase the...

In this video, students learn how to measure mass in kilograms by reading scales marked in different intervals. The teacher explains the concept of mass, the use of different types of scales, and the importance of paying attention to the...

Gravitational potential energy is the energy stored in an object as the result of its vertical position or height. The energy is stored as the result of the gravitational attraction of the Earth and the object. The gravitational...

This program provides a conceptual foundation to help students understand how to convert between English and metric units of mass, volume, length, and temperature. The program also discusses how it is possible to convert between units of...

Three major differences between weight and mass are discussed and three media examples of weight in kilograms are presented (and you should know that weight is NOT in kilograms).

U-values measure how effective a material is an insulator. The lower the U-value, the better the material is as a heat insulator. For example, a cavity wall has a u-value of 1.6, so most of the heat inside the house will stay in the...

In this video, the teacher explains how to estimate mass in kilograms using benchmarks. They review the concept of mass and its measurement in grams or kilograms. The teacher demonstrates how to estimate the mass of different objects,...

Italian tire maker Pirelli is making fuel-saving tires that are more environmentally-friendly by obtaining one of their ingredients from rice husks. One way tires can save fuel is to reduce rolling resistance that is caused in part by...

This is a educational video about solving word problems involving mass and volume using addition and subtraction. The video discusses the units of mass and volume, operation word clues, and common misunderstandings about numbers. The...

This animated math video lesson is all about measuring. Students will love this engaging and interactive video that takes them step-by-step on how to measure and explore different measuring tools in a fun way.

This nugget shows the use of decimals to express length, mass and capacity.

This video explains the relationship between energy and changes of states in matter. It discusses the different changes of state, such as melting, boiling, and condensing, and the fixed temperatures at which they occur. The concept of...

This video is a lecture on Newton's Second Law, which explains the relationship between the acceleration of an object and the resultant force applied to it. The definition of acceleration is discussed, and it is demonstrated how...
