Study Notes
- Objects around us are composed of materials, which can be natural or artificial.
Natural Materials
- These are obtained directly from nature.
- Can be of animal, vegetable, or mineral origin.
- Animal origin:
- Wool or silk obtained from animals, such as wool from sheep used to make jerseys.
- Vegetable origin:
- Derived from plants, like wood for tables or cotton for T-shirts.
- Mineral origin:
- Obtained from the earth and rocks.
- Examples include iron chains or clay pots.
Artificial Materials
- Created when natural materials are altered.
- Paper is made from wood from trees.
- Plastic is created from petroleum extracted from the earth.
- Plastic takes between 100 to 1000 years to fully decompose.
- Reducing plastic consumption is very important.
