Teaching Students About Oxygen in Chemistry

Oxygen is an essential element that all living organisms require for their survival. As teachers, we can engage students in the study of oxygen chemistry to comprehend its significance in our daily lives. Here are important concepts and activities you can use to elevate students’ understanding of oxygen chemistry.

Introduction to Oxygen

Begin by explaining to students what oxygen is and its essential properties. Provide examples of where oxygen is found in our environment, including the atmosphere, and how it is used in everyday life. Illustrate the molecular structure of oxygen and explain the use of simple chemical symbols such as O2 to identify the element.

The Role of Oxygen in Combustion

Provide a basic overview of combustion, including how it works, and explain how oxygen plays a critical role in the reaction. Additionally, introduce terminology relevant to the study of oxygen chemistry, such as oxidation and reduction, and explain how oxidation involves oxygen.

The Properties of Oxygen and Its Compounds

Provide opportunities for students to explore the properties of oxygen, including its physical and chemical properties. Through laboratory experiments and group discussions, students can learn the various compounds of oxygen and their properties. Additionally, introduce students to the impacts of oxygen on human health.

The Importance of Oxygen in the Environment

Encourage students to consider the significance of oxygen in the environment. Explain how oxygen plays a vital role in photosynthesis in plants and the respiration process in animals. Explain how the increase or decrease of atmospheric oxygen can affect different life forms and the environment.

Application of Oxygen Chemistry

Encourage students to apply the concepts learned. Provide opportunities to address real-world problems using what they have learned concerning oxygen chemistry. You might consider asking students to research how oxygen is currently used in specific industries, such as healthcare or food processing.


In conclusion, teaching students about oxygen chemistry is vital, given its essential properties and uses. Encourage students to understand the fundamental principles of oxygen and its impact in the environment and daily life. By involving students in laboratory experiments, group discussions, and real-world applications, you will provide a more in-depth and engaging learning experience.
