Key learning points
- Scientists who investigate materials often control, measure and change variables.
- Control variables are variables that are kept the same throughout an investigation.
- There are some types of investigations where some, but not all, variables can be controlled.
- Astronomers make observations and look for patterns in their data, however, they cannot control variables in space.
- The 21st century astronomer Maggie Aderin–Pocock makes her observations using instruments on satellites in space.
Common misconception
Scientific enquiry is only valid if variables can be controlled and changed.
Teaching slides will explain how some scientist cannot control variables and look for patterns in data and observations instead.
