In this activity, design and construct a LEGO brick wall that is at least 4 inches high. The wall must be capable of withstanding the “flick test” (a simple flick of the finger).

Students will investigate the properties of sturdy structures by constructing a LEGO wall. The wall must be about 6 bricks high and withstand the "Flick Test". The Flick Test involves flicking the top of the wall to see if the wall fails or tips over.
