Study Notes
Introduction to Useful and Harmful Materials
- Module aims to help learners identify useful and harmful materials at home and school, focusing on their properties and labels.
- Two main lessons: Recognizing Useful and Harmful Materials and Importance of Labels in Identifying Materials.
Properties of Useful and Harmful Materials
- Useful materials serve specific purposes due to properties like durability, flexibility, and resistance to elements.
- Reusable examples include empty containers serving as vases or coin banks.
- Recycling examples highlight transformation of materials, such as candy wrappers into curtains.
Risks Associated with Certain Materials
- Some useful materials can pose hazards, like broken glass causing cuts.
- Toxic substances, present in household items, may harm health and the environment if not handled properly.
Classification of Materials
- Materials can be categorized as useful or harmful based on their handling and intended use.
- Useful examples include cooking oil and laundry soap, while harmful materials include broken glass and chemical cleaners.
Importance of Labels
