Many students see falling as ‘natural’ and not requiring an explanation
Resource to Address This
Falling all over the world (5-11)
Children often have a very local understanding of the word "down". In this resource, we invite them to consider what down might mean for children in different places on this planet.View Resource
How things fall (5-11)
This is a focussing activity, that shows the wide variety of things that fall in the children's everyday environment and begins to develop a range of descriptions for these falls.View Resource
Apparent weightlessness (11-16)
The forcemeter reads zero during the fall. Gravity has not been switched off, however, and the mass is still subject to a downward force. It still has weight, which is the unbalanced force resulting in its acceleration throughout its fall.View Resource

Asking students to analyse images from comic strips, rather than the more common force diagrams used in lessons, can be useful in establishing students understanding of forces. The approach also helps to identify misconceptions, based on students ‘common sense’ when they give their descriptions. These ideas are often resilient to change and need to be explicitly challenged in teaching and learning activities.
