National Science Learning Network: Design and Technology Resources

These materials, from the National Science Learning Network, look at electronics, electricity, robotics and control. A range of activities include teachers' notes as well as student activity sheets.

Topics on electricity are aimed to give support and guidance to teachers through articles on:

*current

*resistance

*voltage

There are also a range of activities which help students to look at generating and controlling movement.

In these, students make devices that include:

*an electric racer

*a screw thread linear actuator

*a muscle wire actuator

*a rotating arm actuator
