TOOLS AND PRODUCTION — PRODUCTION UNIT

Subject: Pre-Technical | Age: 13 (Kenya)
Subtopic: Production Unit — what it is, how it works, the tools used and a simple project to practise.

1. What is a Production Unit?

A production unit is a place where people use tools, machines and materials to make goods or services. Examples in Kenya include a small bakery, a carpentry workshop, a tailoring shop, a maize mill or a soap-making corner at home.

2. Main purposes of a production unit

• To produce useful products (food, clothes, furniture, etc.).
• To earn money (business / income).
• To teach skills (training students or apprentices).
• To make efficient use of resources (materials, labour and tools).

3. Important parts (components) of a production unit

1. Inputs: raw materials (e.g., flour, cloth, timber), tools and equipment, money, energy.
2. Process: the work done to turn inputs into finished goods (cutting, sewing, baking).
3. Output: final products ready to sell or use (bread, shirts, chairs).
4. People: manager, workers, helpers and trainees.
5. Storage & sale: safe place to keep goods and a way to sell them (market, shop).

4. Types of production units (simple)

• Manual: work done by hand, using simple tools (e.g., hand-stitched clothes, hand-made stools).
• Mechanised: machines help do work faster (electric sewing machines, small bakery ovens).
• Home-based: small unit inside or near the home (soap-making, beadwork).

5. Common tools and what they do

6. Good rules for a production unit (safety & quality)

• Keep tools clean and in good order. Store them safely after use.
• Wear protective gear when needed (gloves, mask, covered shoes).
• Follow steps carefully — measured work gives better quality.
• Keep workspace tidy to avoid accidents and spoilage.
• Label and store materials and finished goods properly.

7. Simple class project: Make a Pencil Holder (practice production)

Materials: empty tin-can or cardboard tube, decorative paper, glue, scissors, ruler, pencils.

Tools: scissors, ruler, glue, pencil.

1. Measure the height and circumference of the tin-can or tube with the ruler.
2. Cut decorative paper to size (this is sizing — an important production step).
3. Glue the paper neatly around the can or tube (process).
4. Let dry, then test by putting pencils in (output).
5. Check finish: smooth edges, no loose glue, label with your name (quality check).

8. How to evaluate the project (simple)

• Correct size and fit — 4 marks
• Neat gluing and finishing — 4 marks
• Functionality (holds pencils) — 2 marks

9. Short quiz (answer in class)

1. What three things are needed before starting production in a unit? (Hint: starts with I, P, O)
2. Name two production units you see in your town or village.
3. Why is keeping tools clean important?
4. List one safety rule when using a sewing machine.
5. Write one way to improve the quality of a product.

10. Useful words (glossary)

• Input: what you start with (materials, tools, energy).
• Process: the steps used to make the product.
• Output: the finished product.
• Quality: how good or useful the product is.
