Hi, young learners! Welcome back to Primary 5 Basic Science and Technology. In our previous lesson, we learned about the definition of drawing technically and identified drawing instruments. Today, we’re going to learn about Drawing Instruments And Their Uses.
Objectives
By the end of this lesson, you should be able to:
- List different drawing instruments.
- Appreciate the importance of using the correct drawing instruments.
- Demonstrate the correct use of at least two drawing instruments.
- Work collaboratively in pairs to identify and use drawing instruments.
Drawing Instruments And Their Uses
Drawing instruments are tools used to create precise and accurate drawings. They are essential for various fields like engineering, architecture, and design. Some of these instruments include:
What are Drawing Instruments?
Drawing instruments are tools that help us create precise and accurate drawings. They are essential for various fields like engineering, architecture, and design.
The Major Drawing Instruments are:
- Ruler: Used for measuring lengths and drawing straight lines.
- Compass: Used for drawing circles and arcs.
- Set Square: Used for drawing precise angles, typically 30°, 45°, 60°, and 90°.
- Protractor: Used for measuring and drawing angles.
- Pencil: Used for making marks and lines on paper.
- Eraser: Used for correcting mistakes by removing pencil marks.
Each of these tools helps us create accurate and detailed drawings, which are important in many fields such as engineering, architecture, and design.
Lesson Evaluation
To evaluate your understanding, answer these questions:
- List three drawing instruments.
- Explain the use of a compass.
- Demonstrate how to draw a straight line using a ruler.
- Describe how a set square can be used to draw angles.
- Work in pairs to identify the uses of a protractor and discuss your findings.
Conclusion
We’ve learned about the different drawing instruments and their uses. Remember, using the correct instrument is crucial for creating accurate and detailed drawings. Keep practicing and exploring these tools to enhance your drawing skills. Don’t forget to check the comments section if you have any questions, and use the navigation to move to the next lesson.
