Molasses Madness


 Model Description This is a demonstration of the concept of conservation of mass.  By pouring an incompressible fluid (molasses), it is clearly demonstrated that as the velocity of the flow increases, the cross-sectional area of the flow must decrease. This demonstration should take 8-10 minutes. Engineering Principle Mass is conserved when the mass flow rate […]

Choo Choo Train


 Model Description Relative motion and no-slip wheel relationships are brought to life by means of a moving locomotive train. This demonstration should take 10 minutes. Engineering Principle The following relationships are utilized to investigate the velocity and acceleration of the engine piston and push arm given a train velocity and instantaneous position of the wheel. […]

Projectile Motion


 Model Description This is a simple demonstration of the basic principles and behavior underlying projectile motion.  A Nerf gun is used to show that projectile motion can be modeled by a particle having a vertical component of motion with constant acceleration, and a horizontal component with constant velocity (zero acceleration).   This demonstration should take 5-8 […]
