Here you will find detailed instructions for constructing BristleBots, simple robots run by miniscule vibration motors. There is no lesson plan, just a procedure for producing these fun little contraptions. They could be used as an...

Students experience how to construct a simple electromagnet based motor. In groups they explore what a component is and construct a circuit that can rotate the orientation of the magnet by turning the switch on and off. Electromagnetic...

Students investigate the concepts of magnetism and its properties. They construct a magnet and test foods for iron content. Then students define the use of a motor and make their own electric motor while working in small groups. Then...

Students demonstrate that motors work on two different voltages. They connect a single-phase AC motor to run on different voltages.
