Network Olympic Festival

We had a chance to practise our sports skills and develop our Olympic values of respect, friendship and excellence... and it was great fun too!

Being switched on!!

Today we learnt all about using switches in electric circuits, what materials act as conductors of electricity and what materials act as insulators.
We used home-made switches with paper clips, screws, safety pins and aluminium foil. We also tested to see if rubber, coins, paper, wood, plastic and keys would conduct or insulate.

This switch was made using a folded peice of card, covered top and bottom, with aluminium foil!

IT WORKED!!! (can you see the bulb is lit?)

This switch was made using safety pins to complete the circuit across two screws that the crocodile clips were attached to. This also worked as a conductor. We tried replacing the safety pin with rubber, wood, paper or plastic and the bulb did not light up. They were insulators.


Our results were:
Conductors                                                    Insulators
Coins                                                               Rubber
Keys                                                                Wood
Safety pins                                                      Plastic
                                                                        Paper

                                                                      

Making connections!

Here we are at work using a selection of electrical components to tackle the challenge

 "Can you make the bulb light up?"

When the connections were all made and the circuits complete the bulbs lit up.
