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

Labels indicate properties and safety information about products, aiding consumers in making safe choices.
Common labels include:
- Halal: Safe for Muslim consumption.
- Food Allergen Warning: Alerts of potential allergens in food.
- Recyclable: Indicates the product can be recycled.
- Flammable: Warns that the product can easily catch fire.
- Poisonous: Indicates harmfulness to health; potential to cause death.
- Corrosive: Can cause severe burns upon contact.

Consumer Precautions

Importance of reading labels to understand the safe usage and potential hazards of materials.
Labels provide critical information, including expiration dates and handling instructions, crucial for safety.

Activities and Learning Engagement

Activities involve classifying common materials found at home and school and assessing their usefulness or harmfulness.
Emphasis on students using separate sheets for responses encourages engagement and reflection on learning.
