Key conceptTeach from the board

New instruments can reveal evidence that was previously inaccessible: microscopes reveal smaller structures, detectors record wavelengths outside human senses, sensors collect faster and more precise data. New evidence can then refine scientific models.

The relationship also runs the other way. Understanding electromagnetic waves enabled communication and imaging technologies; advances in materials science enable stronger, lighter or more specialised engineered devices. A strong explanation identifies what changed, what new evidence/capability followed, and how that fed back into further development.

Example 2

Complete: scientific understanding → ______ → new observations → refined scientific understanding.

Example 3

Explain one constraint an engineer might face when turning science into a device.

Example 4

Identify the feedback step in a medical-imaging example.

Questions and answersWith answers
  1. How can technology advance science? By extending observation, measurement, analysis and experimentation.
  2. How can science advance technology? Explanations and discoveries provide principles designers can use.
  3. Why “reciprocal”? Each can enable advances in the other over repeated cycles.
  4. What makes an example strong? A specific causal chain, not merely naming a device.
Practice and reviewReady for practice
  • Technology is just applied science. Technology also develops through design, materials, constraints and engineering knowledge.
  • The relationship is one-way. Instruments generate evidence that can transform science.
  • A newer device automatically creates better science. Data still require valid methods and interpretation.
  • Science, technology and engineering are identical. Their purposes differ even when projects overlap.
