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).

In their first adventure, the SI Superheroes (aka the International League of Measurement Units) use the power of measurement to help a stranded soccer player get home.

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,...

This video is a lecture presentation on gravitational potential energy. The presenter defines gravitational potential energy and explains how changes in height can affect it. They also provide equations to calculate gravitational...

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...

Measure mass using units of gram.

In this live-action program viewers will learn that the SI is an international system of standardized measurement used by scientists worldwide. Students will come to understand that the SI is made up of a list of base units defined by...

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.

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...

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 specific latent heat, which looks at the energy absorbed or emitted by a substance as it changes states (solid, liquid, or gas). The lecture discusses two equations that can be used to calculate the amount of...

It explains density and its unit, relative density and determination of relative density of a solid.

In this video you will about weight, force, mass and gravity. When it says 56 kilograms on your bathroom scales, what are you actually measuring? Well, if you said weight, like most people would, then you are sort-of wrong! Kilograms are...

This video provides an introduction to the metric system and its importance in scientific communication. It explains the history of the metric system, its base unit of measurement (the meter), and how larger and smaller measurements are...

When a substance changes its state, heat energy is involved. This energy is used not to heat up the substance, but to separate the molecules from each other. This is known as specific latent heat. Specific latent heat is defined as the...
