Answer:Knowing about the properties of materials helps us make better decisions in everyday life. It allows us to choose the right materials for specific uses—for example, using metal for cooking pots because it conducts heat well, or using plastic containers because they are lightweight and waterproof. Understanding properties like strength, flexibility, or absorbency also helps us take care of our belongings and use them safely. It even helps us reduce waste by knowing which materials can be reused or recycled. In simple ways, this knowledge makes daily tasks easier, safer, and more efficient.
