| Power source | Human effort | Electricity or fuel |
| Speed of work | Slow | Fast |
| Example (Cooking) | Firewood | Gas or electric cooker |
D. Class Activities
Activity 1: Show and Tell
Show pictures or real items (e.g., broom, grinding stone), and pupils say what it is used for.
Activity 2: Sorting Game
Give pupils cards of tools—let them group into underdeveloped and modern tools.
E. Evaluation (Assessment)
What is technology?
What does underdeveloped technology mean?
Mention two examples of underdeveloped technology.
Is a grinding stone an example of modern or underdeveloped technology?
Mention one difference between underdeveloped and modern technology.
F. Assignment
Draw and label two underdeveloped tools.
Write one sentence about each tool and how it is used.
G. Conclusion
Technology helps us do work more easily.
Underdeveloped technology uses simple tools and takes more time.
We must understand both old and modern ways to appreciate how things have improved.
