It explains that air is present in water and soil. It also talks about the interdependence of plants and animals for oxygen and carbon dioxide.

The video discusses the composition of air, specifically the gases nitrogen, oxygen, argon, and carbon dioxide. The presenter explains how these gases react with certain compounds and how they can be made from other substances. The video...

Students will learn about the different layers of the atmosphere. The changes in the atmosphere are explained using examples of contemporary environmental conditions brought about by human behavior. The oxygen cycle and the carbon cycle...

This video is a lecture presentation on the production of heat and carbon dioxide in respiration. The presenter explains the process of aerobic respiration, which is a chemical reaction between glucose and oxygen to produce carbon...

One of the most important factors when it comes to mixing any gas with a liquid is solubility, and carbon dioxide is highly soluble in water. In fact, it's the most soluble of the common, non-toxic gases with high solubility. To give you...

Learn the basics about Testing for hydrogen, oxygen, carbon dioxide and chlorine. Why do we need to test these particular gases? Find out more in this video!

The video is about the circulatory system, which is a group of organs that work together to transport substances to and from cells in the body. The video explains how blood flows around the circulatory system and how blood vessels are...

Learn the basics about climate change and how burning fossil fuels adds extra carbon dioxide to the atmosphere, and how this then leads to climate change. Fossil fuels, like oil, coal and natural gas, are the remains of living things...

This program addresses many of the cycles conducted by animals including those of migration, hibernation, and patterns relating to day and night. The cycles that affect all living things are discussed including the air we breathe and the...

Carbon dioxide is a product of one of the most important chemical reactions in the world: combustion. Combustion is how a lot of people in the world heat their homes and power their cars. It also unfortunately contributes to the...

In this live-action program viewers will learn that oxygen is necessary for life and is used to create energy in cellular respiration. Students will come to understand Cellular respiration is required for life, and breathing, which is...

Through photosynthesis, plants take in carbon dioxide from the air and split it and use it (and water) to make carbohydrates. So surely plants can help us reduce carbon dioxide in the air? Possibly... But equally, the carbon in plants is...

Dr. Forrester describes the body’s respiratory system by highlighting each component of the system and explaining how the diaphragm, larynx, trachea, bronchioles, and air sacs aid the lungs in the human body’s exchange of oxygen for...

If we reduce our use of fossil fuels, we will reduce the amount of extra carbon dioxide that we put into the atmosphere. There are 2 ways to reduce our carbon dioxide emissions from burning fossil fuels: 1) We make our processes more...

Watch part 2 of the videos on the Carbon Cycle, as a part of environmental chemistry. Photosynthesis and respiration help carbon to be cycled in nature by using energy from the sun. As living things grow, they have to build up large...

Photosynthesis and respiration help carbon to be cycled in nature by using energy from the sun. As living things grow, they have to build up large polymer molecules from small molecules. Protein comes from joining amino acids together,...

Watch the first part of our Carbon Cycle videos, as part of environmental chemistry. Photosynthesis and respiration help carbon to be cycled in nature by using energy from the sun. As living things grow, they have to build up large...

Ever wondered how to conduct a chemical test for the presence of colourless and odourless gases? Watch this to find out how!

This video is a lecture presentation that focuses on atmospheric pollution, discussing the effects of different types of pollution on the environment and living organisms. The lecturer covers the biological consequences of pollution...

Atoms or molecules combine to form a new compound in a synthesis reaction. Examples include the addition of oxygen to magnesium metal to create magnesium oxide and the addition of carbon dioxide to water to crete carbonic acid. A...

Unlock the mysteries of the respiratory system with this catchy tune! From the nose down to the alveoli, journey through the process that keeps us all alive. Dive into the wonders...

Learn the basics about the properties of oxygen.



Oxygen is a gas, it has no smell, colour, or taste; but without it, we as humans would not be able to inhabit pla

net Earth.

When cooled to a very low...
