Hi, young learners! Welcome back to Primary 5 Basic Science And Technology. In our previous lesson, we learned about the Function Of Vehicle Internal Parts. Today, we’re going to learn about Definition Of Drawing Technically, Identification Of Drawing Instruments.
Objectives
By the end of this lesson, you should be able to:
- Define technical drawing.
- Appreciate the importance of precision in technical drawing.
- Identify and handle different drawing instruments.
- Collaborate with peers to identify drawing instruments.
Definition Of Drawing Technically, Identification Of Drawing Instruments
What is Technical Drawing?
Technical drawing is a type of drawing that uses precise lines and symbols to communicate how something works or is built. It’s used by professionals in fields like engineering, architecture, and manufacturing. Technical drawings are important because they provide clear and detailed instructions for creating objects.
Drawing Instruments
There are several tools used in technical drawing, and they are:
- Pencil: Used for drawing lines, sketching, and shading.
- Ruler: Used for measuring and drawing straight lines.
- Compass: Used for drawing circles and arcs.
- Set Square: Used for drawing right angles and parallel lines.
- Protractor: Used for measuring and drawing angles.
- Eraser: Used for removing mistakes and unwanted lines.
Evaluation Questions
Now that you’ve learned about technical drawing and drawing instruments, let’s see if you can answer these questions:
- What is technical drawing?
- What are three drawing instruments and their uses?
- How do you use a compass to draw a circle?
- Why is precision important in technical drawing?
- What are some examples of how technical drawings are used in everyday life?
Conclusion
Today, we learned about technical drawing, which is a precise way to communicate how things work or are built. We also learned about the different tools used in technical drawing. Remember, technical drawing is an important skill for anyone interested in engineering, architecture, or other technical fields. Keep practicing your drawing skills, and you’ll be able to create amazing things!
