Electricity Week Class 4

Last week, Class 4 enjoyed our Science themed week based on electricity. During the course of the week, as Scientists, pupils:

  • Explored different types of circuits
  • Investigated different components in a circuit
  • Created our own circuits using a range of materials
  • Explored different types of switches in a circuit, such as pressure switches and toggle switches
  • Created and tested our own switches, using them to control various components in a circuit
  • Solved problems applying our knowledge of circuits. 

On Friday, Class 4 were set with the challenge: ‘Can you protect the crown jewels?’ Their mission, which they chose to accept, was to create an alarm system to protect the crown jewels in the tower of London. The alarm systems had to have audio and visual alerts, in order to help the guards to detect any attempt to steal them. Furthermore, the alarm had to provide three point protection: entry to the Jewel House; entry to the Jewel Room; and moving the Jewels.

Some pupils had to construct a circuit that activated when the Jewel House is entered. They had to consider whether the alarm was activated by a door, a window or another point of entry. Their alarm had to activate a warning light in the Guard Room and an audible warning around the Tower. It also had to be turned off by the Yeoman Warders in the Guard Room.

Other pupils had to construct a circuit that activated when the Jewel Room was entered. They were told that there were no windows in the Jewel Room, only a door. Their  alarm had to activate a warning light in the Guard Room and a continuous audible alarm around the Tower and in the Warders’ barracks. The Yeoman Warders had to be able to turn off the alarm in the Guard Room.

The last group had to construct a circuit that activated when the Jewel Box was opened or moved. The alarm had to activate two warnings lights in the Guard Room and a continuous audible alarm around the Tower and in the Warders’ barracks.

Pupils thoroughly enjoyed the opportunity to use the fantastic resources that were loaned to us, courtesy of the Ogden Trust, to carry out scientific investigations and to problem solve. It was certainly challenging – however, the pupils worked brilliantly together and showed some real creativity with their designs.  

Well done Class 4!
