Teacher’s notes
How science ideas change over time
Rationale
The accepted views of science knowledge can change over time. Changes
can result from new science observations, but can also be affected by
social, political or religious convictions. To develop a deeper understanding, students need to investigate the context of the time in which science
ideas were developed.
Activity
Curriculum level 7-8
Planet Earth and beyond Topic
Space
Type of investigation
Researching
What you need
- Information, anecdotes and stories about scientists, astronomers or
philosophers who faced opposition for their science theories or investigations.
Note: Supporting activity resources are provided
below.
Focus
- Do science explanations that are accepted as valid change over time?
- Are science ideas influenced by the views held by society?
- Why might new science ideas be opposed?
- What do we need to know about the context of the era in which a scientific
idea arises, in order to understand the opposition it might meet?
Exploration
The students work, in groups or individually, to research the life and ideas of a person involved in the development of a scientific theory which faced opposition from the society in which it was developed.
- What challenges or opposition did this person face in having their
theories accepted?
- Why?
- Do you think those challenges/opposition are still there today?
- What sort of challenges or opposition (for example, ethical or economic
challenges) do you think present-day scientists face?
The students present their findings to the class in an oral, written
or other format.
Extension
- Is science knowledge that is currently accepted likely to be subject
to challenges is the future?
- Should this affect how we carry out investigations to generate new
science ideas?
Reflection
- How did prevailing world views affect the acceptance of scientific
ideas in the past?
- How might the general world view and/or the variety of world views
today influence the acceptance of science ideas now?
- Do people recognise that they have a particular way of looking at
the world?
- Do you recognise that you have a particular way of looking at the
world?
- What questions do you need to ask to analyse your own world view?
