Weight and Mass - Planetary Weight

Useful when teaching the difference between weight and mass. Pupils should illicit the idea that if they were to visit another planet, their mass would stay the same but their weight would change as a result of gravity.

Older or more able groups I ask to research the gravitational field strength. Younger or less able groups I send of a tour of the solar system. Put out the planets and ask them to find the gravity.

Unit for gravity is given as N/kg you may wish to change in to m/s/s depending on group and syllabus.
