Chapter Overview
The chapter 'Who is Heavier?' teaches students how to compare the weights of different objects using real-life examples. Students learn to use balance scales and estimate weights by observing and experimenting. They are introduced to both standard units (grams and kilograms) and non-standard units (like marbles or blocks) for comparison. The chapter promotes critical thinking and reasoning while laying a foundation for understanding mass and weight in everyday situations.
