Human Sulfur Metabolism (Part 1): Hydrogen Sulfide and Atomic Sulfur!

In this video, we learn about the metal palladium, which is part of the elite group of metals called the Platinum Group. The video highlights the properties of Palladium, including its usefulness as a catalyst, high resistance to wear...

Hemoglobin 1

Myoglobin 1

The video is a lecture presentation on the extraction of metals. The presenter begins by discussing how the method used to extract a metal from its ore depends on the metal's reactivity. The lecture then covers the extraction of iron...

This nugget explains pollution of the layers surrounding the earth, air pollutants, global warming and green house effect, acid rain, ozone hole, photochemical smog.

The video discusses atmospheric pollution and the effects of burning fossil fuels. It explains the pollutants created through combustion, such as carbon dioxide, particulates, carbon monoxide, sulfur dioxide, and nitrogen oxides. The...

This video explains different chemical reactions used for extracting metals from their oxides. The video starts with the simple method of reduction with carbon for metals such as iron, where the metal oxide is reduced, and carbon is...

It explains preparation of Dihydrogen by Laboratory Method & Commercial Production

In this week’s episode, we discover secrets in buried soils; we learn how elephant seals protect their organs when diving; we learn about Amulet -- the future in wearable technology; and, finally, we explore the fast-moving Thwaites...

It explains the need for management of fossil fuel and talks about various practices that can help in the management of fossil fuels.

In this video, do a couple examples of pulmonary function tests for obstructive and restrictive defects.

Cytochrome c Oxidase

In this video, we explore the pathway for red blood cell destruction including the full degradation of heme b from the liver and spleen to renal and gastrointestinal elimination.

View from space of the Australian bushfires, from the December 30th 2019 to January 2nd 2020. Based on data from JAXA / JMA / Himawari.

In this video, we will look at the chemistry behind the production of iron from iron ore. In early Earth history, iron, like all other metals, would have been found as an element in the crust of the planet. Later when plants evolved that...

The video explains how the combustion of fuels produces atmospheric pollutants, such as greenhouse gases, carbon monoxide, carbon particulates, sulfur dioxide, and nitrogen oxides. It describes the chemical reactions that occur during...

This program covers part 1 of the very important topic of the atomic theory of matter. We discuss how atoms combine together to form new compounds. Students review the law of conservation of mass and how the mass of the substances at the...

This live-action video program is about the word air. The program is designed to reinforce and support a student's comprehension and retention of the word air through use of video footage, photographs, diagrams and colorful, animated...
