Identifying articles and materials used for various purposes in Coal and Petroleum – Class 8 Science Experiment
Chapter Name: Coal and Petroleum
Activity Name: Identifying articles and materials used for various purposes in Coal and Petroleum
Activity Description:
In this activity, students are required to collect information from their grandparents or older people about the materials that were used for various items in the past (10 years, 50 years, and even 100 years ago). They will then compare these materials with the ones used at present.
Required Items:
- Table with three columns: Column (A), Column (B), and Column (C)
Step by Step Procedure:
- Set up the table with three columns: Column (A) for activity and item names, Column (B) for past materials, and Column (C) for present materials.
- Ask your grandparents or older people about the materials that were used for the items mentioned in Column (A) in the past.
- Write down their responses in Column (B) of the table.
- Research and find out the materials that are commonly used for the same items at present.
- Write down the present materials in Column (C) of the table.
- Compare the materials used in the past and the materials used at present for each activity and item.
Experiment Observations:
The observations will depend on the responses collected from grandparents and older people, as well as the research on present materials. Students will notice the shift in materials used over time, with advancements in technology and changes in preferences.
Note down your observations in table format:

Precautions:
- Ensure that students gather information from reliable sources and verify the accuracy of the materials used in the past.
- Encourage students to respect the knowledge and experiences shared by older generations.
Lesson Learnt from Experiment:
Through this activity, students will learn about the historical evolution of materials used in various activities and items. They will understand how technology, innovation, and societal changes have influenced material choices over time. Additionally, the activity may foster an appreciation for sustainable practices and environmentally-friendly materials.
