Combustion

In the Combustion main lesson, students would explore the fascinating phenomenon of combustion, including its principles, processes, and practical applications. Here are some main points of knowledge that students might learn throughout the series:

Introduction to Combustion:

• Fire Safety: Before starting all of the students will be taught basic fire safety and have an opportunity to use a fire extinguisher.

• Definition: Students would understand the concept of combustion as a chemical reaction that involves the rapid oxidation of a fuel in the presence of oxygen, resulting in the release of heat, light, and often the formation of new substances.

• Components of combustion: Students would learn about the three essential components of combustion: fuel, oxygen, and an ignition source, commonly referred to as the "fire triangle".

• Types of combustion: Students would explore different types of combustion, including complete combustion and incomplete combustion.
  

Properties of Fuels:

• Types of fuels: Students would study various types of fuels, focusing on natural materials that burn. Examples may include wood, coal, oil, natural gas, and some metals.

• Combustion characteristics: Students would examine the combustion characteristics of different fuels, including their ignition temperature, flammability limits, and the products of combustion.
  

Combustion Reactions:

• Chemical reactions: Students would explore the chemical reactions involved in combustion, providing a foundational introduction to chemistry.

• Energy release: Students would understand that combustion is an exothermic process, meaning it releases energy in the form of heat and light.

  
  

Practical Applications of Combustion:

• Energy production: Students would explore how combustion is utilized for energy production, such as in the burning of fossil fuels to generate electricity or heat homes and the use of combustion engines in vehicles.

• Cooking and heating: Students would understand how combustion is employed in cooking appliances, such as stoves and ovens, as well as in heating systems like furnaces and boilers.

  
  

Environmental Impact and Combustion Technologies:

• Environmental considerations: Students would explore the environmental impact of combustion, including air pollution, greenhouse gas emissions, and their contribution to climate change.

  
  

Throughout the series, students would engage in hands-on experiments, demonstrations, and discussions to deepen their understanding of combustion. They will conduct controlled burn experiments, investigate the efficiency of different fuels, explore the effect of oxygen availability on combustion, and examine the composition of combustion products.
