Material Mania: Exploring the Properties of Matter
Lesson Description
Video Resource
Key Concepts
- Materials are the substances that objects are made of.
- Materials have observable properties, such as color, texture, flexibility, and hardness.
- The properties of a material determine its suitability for different purposes.
Learning Objectives
- Students will be able to identify different materials (e.g., wood, plastic, metal, glass, fabric, rubber).
- Students will be able to describe the observable properties of different materials (e.g., hard, soft, flexible, waterproof).
- Students will be able to explain why certain materials are chosen for specific purposes based on their properties.
Educator Instructions
- Introduction (5 mins)
Begin by asking students to name different objects they see in the classroom. Then, ask them what those objects are made of. Introduce the concept of 'materials' and explain that different materials have different properties. - Video Viewing (7 mins)
Play the 'Materials And Their Properties' video from ClickView. Instruct students to pay attention to the different materials mentioned and their properties. - Group Discussion (10 mins)
After the video, divide the class into small groups. Each group will discuss the different materials they saw in the video and their properties. They will also discuss examples of how these materials are used in everyday life. - Material Sort (15 mins)
Provide each group with a collection of small objects made from different materials (e.g., a piece of fabric, a plastic spoon, a metal key, a rubber band). Have them sort the objects based on their properties (e.g., hardness, flexibility, waterproofness). - Wrap-up and Assessment (8 mins)
Review the key concepts of the lesson. Administer the multiple-choice and fill-in-the-blank quizzes to assess student understanding.
Interactive Exercises
- Material Scavenger Hunt
Students go on a scavenger hunt around the classroom or school to find objects made of different materials. They then describe the properties of each material they find and explain why that material is suitable for that object. - Design a Product
Students design a product (e.g., a backpack, a toy, a piece of furniture) and choose the materials that would be best suited for making it. They must justify their choices based on the properties of the materials.
