Where do all these materials come from? Can you locate their source?
All materials come from nature, either directly or after processing.
Wood comes from trees.
Metals are extracted from ores (rocks and sediments) dug up from inside the Earth.
Cloth is made from fibres obtained from plants (like cotton), animals (like wool from sheep), or synthetic sources.
Glass is mostly made from sand.
These natural resources are processed to create the materials we use daily.
Explanation
The chapter on Page 8 introduces the concept of sources of materials. The 'Chain Game' activity helps students trace materials back to their origins. Wood comes from trees, metals from ores inside the Earth, and glass from sand. Understanding where materials come from helps students appreciate natural resources.
Solution Steps
All materials originate from nature, either directly or after processing
Wood comes from trees as a natural source
Metals are extracted from ores found inside the Earth
Cloth is made from fibres obtained from plants, animals, or synthetic sources
Glass is primarily made from sand
Natural resources are processed to create everyday materials
