### Activity No # 3 - Inertial property of mass

• Estimated Time - 30 minutes
• Materials/ Resources needed
• Prerequisites/Instructions, if any
• Multimedia resources

This video describes the inertial property of mass

• Process (How to do the activity)
1. Let the students watch the video
2. Ask them to write situations where they have faced inertia
• Developmental Questions (What discussion questions)
1. When do we say something has inertia? (When it does not change its position)
2. What does inertia do? (Resists change)
3. Does it depend on size of the object? (Yes/ No/ Not always)
4. If not on size, what does it depend on? (It depends on how much matter ther?e is - mass)
5. When we observe inertia, we can say object has mass
• Evaluation (Questions for assessment of the child)
1. Does inertia increase with size?
2. Will an object have inertia when it moves?
• Question Corner
1. How can I tell that an object has mass or not?
