This pre-assembled DC motor is designed for students to learn about electromagnetic forces. The open structure resembles the diagram found in many textbooks.

This motor generator demonstrates both shunt wound, and series wound connections for motors and generators, and can be used with AC or DC supplies. Motor is easily dismantled to change the configuration.

Density Blocks

This 3“ metal ball will float in cold water and sink in hot water. Use it to demonstrate the effects of temperature and mineral content on water’s density.

These blocks demonstrate the density of four different materials-aluminum, brass, steel, and copper. Each cube is 3.2 cm and has a hook. Specification sheet included.

Use this set of nine cubes to investigate density by comparing cubes that are made of different materials but are the same size (2cm by 2cm by 2cm). Their materials are as follows: copper, brass, aluminum, iron, zinc, acrylic, plastic, wood, and

1216T40 (DCSET4): This set includes one each of acrylic, pine, nylon, and aluminum cubes packaged in a poly bag. Includes a reference table showing density values of individual specimens.
