MYTHconceptions 7-24: Tablecloth Viola!
Today the students investigated if it was possible to magically pull a tablecloth off of a table so that everything on top of the tablecloth remains as it was. In order to understand the plausibility of this claim, students first learned about Newton’s first law of motion: objects tend to stay still if they are still or continue moving if they are moving. Students then planned, tested, and carried out various scenarios to remove a tablecloth without disrupting the table setting resting on it.
Ask your student: What happens to an object at rest if no force acts on it? (it stays at rest) Were you able to pull the tablecloth out without disrupting the objects on top of it?
