Answer:
Get students to think about whether the gravity force on them now is a lot more/a bit more/the same/a lot less/a tiny bit less/zero when they are:
in the same classroom with all the air pumped out
on top of Mt Everest
on top of the tallest building in Melbourne
on the moon (1/6 the size of Earth)
in the classroom but the Earth has stopped spinning
next to another astronaut in deep space
the only astronaut in deep space
in free fall after jumping from a plane.
Collate responses and conduct a whole class interpretive discussion to clarify students’ thinking and inform further teaching.
