Detailed

Extended Learning — Activities and Projects

This section focuses on engaging students through hands-on activities and projects to deepen their understanding of combustion and fuel properties. Students are encouraged to survey the availability and costs of various fuels in their locality while considering their calorific values. They will explore fire safety protocols and the effectiveness of different fire extinguishing methods by investigating fire extinguishers' presence in local establishments.

Further activities include making models to see the effects of chemical reactions with baking soda and vinegar, emphasizing understanding combustion clearly. Students will also discuss the importance of LPG for household use and safety precautions while using it. These activities not only reinforce classroom learning but also connect scientific concepts to real-life experiences, enabling students to apply their knowledge practically and meaningfully.

Key Concepts
