Today we brainstormed variables that might affect the acceleration of an object that is experiencing an unbalanced force.  One group wondered what would happen if we were able to “funnel” the wind being blown from the cart down.  They hypothesized that the faster moving air at the end of the funnel would provide more “push” on the cart.  However, one of the group members saw a problem with the fact the air is pushing in a smaller area.  They began by trying to create a paper funnel without too much luck.  One found this nice plastic funnel in my chem equipment drawers.

They had a few problems with this set up.  Do you know what they were?  They are thinking of doing some modification to the design, so I’ll wait to share tomorrow what they come up with.
