Technology in Science
Technology applies science to solve problems
Today we will learn how technology affects daily life, agriculture, medicine and space science. We will also discuss problems caused by technology.
Science in Action
From phones to farming tools, technology changes how people live and work.
By the end of this lesson, you should be able to:
Define technology
Describe technology as the application of scientific knowledge and discoveries.
Classify objects
Classify objects as natural or man-made/artificial.
Use simple technology
Demonstrate proper use of simple technology such as a watch, telephone and camera.
Explain impact
Explain the impact of technology on agriculture, medicine and space science.
Solve problems
Describe how technology contributes to solving problems.
Identify problems
Identify problems caused by technology.
Technology is applied science
Example
Science explains how light forms an image. Technology applies this knowledge to make cameras and phone cameras.
Another example
Science explains how plants need water. Technology applies this knowledge to design drip irrigation systems.

Technology is best described as...
Objects can be natural or artificial
Natural objects
Natural objects are found in nature and are not made by people.
Examples: stone, tree, river, soil, animals, sunlight.
Man-made/artificial objects
Man-made objects are designed or made by people using knowledge, skills and materials.
Examples: phone, camera, watch, tractor, bridge, syringe.
Classify each object
| Object | Choose |
|---|---|
| River | |
| Mobile phone | |
| Tree | |
| Camera |
Use technology safely and correctly
Watch
Use it to tell time, plan activities and arrive on time.
Telephone
Use it for communication, emergency calls and sharing information responsibly.
Camera
Use it to record observations, document experiments and capture evidence.
Interactive use
Choose a responsible use of technology.
Technology helps improve food production
Tractors
Help farmers plough and prepare land faster than using hand tools only.
Irrigation
Supplies water to crops, especially where rainfall is limited.
Weather tools
Help farmers plan planting, harvesting and protection of crops.
Quick check
Which technology helps farmers water crops when rainfall is low?
Technology helps people understand the body and the universe
Medicine
- Thermometers help measure body temperature.
- Microscopes help scientists see tiny organisms.
- X-ray machines help doctors see bones.
- Vaccines and medical equipment help prevent and treat diseases.
Space science
- Telescopes help observe planets, stars and galaxies.
- Satellites help with weather forecasting and communication.
- Spacecraft help scientists explore space.
- Rockets carry instruments and satellites beyond Earth.
Match technology to field
| Technology | Choose field |
|---|---|
| X-ray machine | |
| Satellite | |
| Tractor |
Technology can be designed for real needs
| Problem | Technology solution | How it helps |
|---|---|---|
| People need clean drinking water | Water filter or treatment system | Removes dirt and some harmful substances. |
| Farmers need water for crops | Drip irrigation | Delivers water directly to plants and reduces waste. |
| Doctors need to see inside the body | X-ray machine or scanner | Helps identify injuries or illness. |
| People need information quickly | Radio, phone or internet | Shares messages, warnings and learning materials. |
Problem-solving task
Technology can also create problems
Waste
Old phones, batteries and machines can create electronic waste.
Pollution
Factories, vehicles and poor waste disposal can pollute air, water and land.
Misuse
Technology can distract learners, spread false information or invade privacy.
Responsible solutions
- Repair and reuse devices where possible.
- Recycle safely and avoid dumping electronics.
- Use devices for learning and useful communication.
- Protect privacy and think before sharing information.
Balanced thinking
Good scientists and citizens look at both benefits and risks before deciding how technology should be used.
