- Examples of objects with different weights

## Lesson Content and Timeframe

### Introduction (5 minutes)

The teacher will introduce the topic and explain that weight is a measure of how heavy an object is. The teacher will ask students if they can name some units of weight measurement.

### Definition of Weight (10 minutes)

The teacher will define weight as the force that gravity exerts on an object. The teacher will explain that weight is a vector quantity, meaning it has both magnitude and direction. The teacher will illustrate this by drawing a diagram on the whiteboard.

### Units of Weight (10 minutes)

The teacher will introduce the common units of weight measurement, such as grams, kilograms, pounds, and ounces. The teacher will explain the relation between these units and give examples of objects that can be measured in each unit.

### Converting Units of Weight (15 minutes)

The teacher will explain how to convert from one unit of weight to another. The teacher will use examples to demonstrate this, showing how to convert from grams to kilograms, pounds to ounces, etc. The teacher will also encourage students to practice converting units of weight on their own.

### Homework (5 minutes)

Students will be given a worksheet to test their understanding of weight and unit conversions. They will be asked to solve problems involving weight measurement and answer questions related to the lesson.

## Conclusion

Students will be allowed to ask questions and clarify any doubts they might have before the end of the lesson. The teacher will summarize the key points covered in the lesson and remind students to complete their homework before the next class.
