By the end of this learning object, the learner should be able to: Identify Oxidation – reduction reactions by gaining or losing electrons

Zoom into the world of 'Enzymes,' where kids will learn how these tiny but mighty helpers speed up reactions in our bodies! It's a microscopic journey to see the science that makes us work.

Learn about the components of a chemical reaction, including reactants and products, and how chemical bonds are affected during the process. Explore examples like cookies and rusty bike fenders to understand these concepts...

Explore the concept of the conservation of matter, which states that during a chemical reaction, matter is neither created nor destroyed. Learn how this fundamental principle applies to various examples, from dissolving sugar in tea to...

Explore the concept of energy changes in chemical reactions, including exothermic and endothermic reactions. Learn how chemical reactions can either release or absorb energy in the form of heat or light, with examples ranging from...

Explore the various changes in properties that occur as a result of chemical reactions. Learn how to recognize signs such as color change, emission of odor, production of gas, and formation of precipitates, with practical examples like...

Explore the concepts of physical and chemical changes in matter through examples like cookies and rust. Learn how to distinguish between physical properties and chemical reactions.<b<br/>r/>

All About Chemical Reactions part 1

We’re back with another episode on climate change and health, and this time we’re looking at some of the indirect health effects, with a focus on how things like air pollution and allergens arise from a warming planet and make us sick,...

Dive into the frigid world of Nicolas Vanier as he trains on the Vercors plateau, preparing for the grueling conditions of the Siberian winter. This feature explores how Nicolas and his sled dogs adapt to severe cold, focusing on...

For this fun experiment, we have transformed our kitchen into a laboratory. We put on our lab coats, gloves and safety glasses to observe this amazing reaction that produces a lot of foam and a bit of heat too.

This video is answering the question of what is a chemical reaction.

This video is answering the question of what are the signs that a chemical reaction is occurring.

This video is answering the question of how fast do chemical reactions occur.

This video is answering the question of how are chemical reactions useful.

This video is answering the question of do chemical reaction affect energy.

Dr. Forrester provides an overview of the various systems in the human body. She then introduces the circulatory system and describes the critical functions of this amazingly efficient system.

Professor Dave explains the science and theory behind pericyclic reactions (Part One)

We've seen organometallic reagents featuring magnesium, as well as lithium, so how about copper? These are called organocuprates, or sometimes Gilman reagents. What do they look like? How do we make them? What do we do? Let's take a look!
