Our scientists competed in marshmallow races today.  This activity led to some deeper thoughts and discussions about friction from the carpet versus the tile, and also all the different factors that would affect the outcome of the race such as how you position the marshmallow, what kind of breaths you take, and the speed at which you are breathing.  I am really  focusing on the kids not looking for the "right" answer but letting their ideas lead to deeper thinking and new questions.
