Combine the Power Add-On Set to the Mechanisms Base Set and watch as your students bring their models to life! With the addition of the motor, battery box, and connecting leads, your students can build four new models and solve two additional problem-solving tasks. Building instructions for the new models are included. Activities are included in the Mechanisms Activity Pack.

If you purchased the Mechanisms Activity Pack prior to August 2007, call us and we’ll send the Power Add-On activities at no charge.

This set previously appeared as, and is the same as, the Science & Technology Power Add-On Set.
