Modified Newton’s Cradle Demonstrating Mechanical Impedance

A Physics professor and inventor at the University of Wisconsin – Whitewater has developed a modified Newton’s Cradle that allows the user to visualize and test the concept of mechanical impedance in addition to momentum and energy conservation. The traditional version of Newton’s cradle has a cradle of identical metal spheres. In this modified and improved device, the user is able to interchange these spheres with ones of varying mass and material composition. By allowing the user to strategically align and create a unique cradle, they have the opportunity to visualize mechanical impedance. For example, a sphere with a small mass would have the ability to strike the cradle and lift a sphere of greater mass on the opposite side if the spheres in-between had a gradient of increasing mass themselves. The possibility of changing a sphere at any position in the cradle allows for an exceptionally large number of possible experiments and would overall lead to an enhanced understanding of the aforementioned physics concepts, something a traditional cradle device does not provide for.

Laboratory Mouse Procedural Techniques Training DVD and Manual

Trainers at the RARC have developed a training DVD that can be used as a resource or refresher for procedural techniques on mice. This DVD, called “Laboratory Mouse – Procedural Techniques,” provides content similar to that of the in-person training course offered through the RARC.

Procedures and techniques demonstrated in the DVD include handling, restraint, oral gavage, identification and common bleeding and injection techniques. All procedures and techniques shown in the DVD are approved by the University of Wisconsin’s Animal Care and Use Committee (ACUC).
