Science and Technology Advance Together
Investigate how scientific discoveries and technological advances influence each other, including how new tools allow better observations, measurements and applications. Use evidence and clear reasoning in longer answers.
Part A
Short-answer questions
What is the difference between science and technology?
Give one example of technology that helped scientists collect better evidence.
How can scientific knowledge lead to a new technology?
Why did microscopes change the study of living things?
How can sensors improve data collection?
Name one technology used to study Earth or space.
Explain why better measurement can lead to better scientific models.
Give one example of a medical technology based on science.
How can technology also create new science questions?
Correct this misconception: “Technology is just applied science and never changes science itself.”
Part B
Long-answer questions
Explain how a technology such as the microscope, telescope or data logger enabled a major science advance.
Describe how scientific understanding of electricity made modern communication technologies possible.
Compare how old and modern measurement tools could affect the quality of investigation data.
Explain how satellite technology has improved understanding of weather, climate, oceans or land use.
A student says new technology only makes science faster, not better. Evaluate this claim using an example.
Describe how medical imaging uses science knowledge and also provides evidence for further science.
Explain how advances in computing or modelling can help scientists test complex systems.
Choose one technology and trace the cycle: science idea → technology → new evidence → improved science idea.
Discuss one ethical or social issue created by a new science-based technology.
Write a full response explaining why science and technology often develop together rather than separately.
Part C
Research and understanding task
Research one technology that transformed scientific understanding, such as microscopes, telescopes, DNA sequencing, satellites, particle accelerators or medical imaging. Explain the science behind it and what new evidence it made possible.
