The "Starting Science" series is designed to introduce students to some of the important skills associated with a hands on approach to the subject. In completing this series of thematic investigations children are required to utilize skills such as observing, classifying, recording, predicting, sequencing, comparing and contrasting, identifying, and labelling.

To give background to each activity page, sets of teachers’ notes have been provided so that the page itself is able to become a supporting activity for the lesson, rather than the lesson itself. However, while suggestions have been made, teachers will quickly see how they can modify both teaching outlines and activity pages to suit the needs of their class.
The activities in this book, Book Two, revolve around the themes of:
* Electricity & Magnetism * Light & Sound * The Weather & its Effects * Forces & their Effects

* Human Effects on the Environment

Excerpt

Starting Points

  • Ask the children if they know what an insulator is.
  • Do they have insulation in their house? What purpose does it serve?
  • Point out that just as that type of insulation stops heat from travelling out through the roof of their house, so an electrical insulator stops electricity from travelling along the circuit.
  • Likewise the analogy of a bus or train conductor could be drawn - someone who allows you (electricity) to continue a journey.

Conductors and Insulators

Some materials allow electricity to travel through them. These are called conductors.

Materials which do not allow electricity to travel through them are called insulators.

Put a 4 next to the things you think will conduct electricity.

Put a 8 next to the things you think will not conduct electricity.

Use your circuit to check your predictions.
