Making switches

• Our scientists have been busy making a range of
  switches for their circuits. However, they have
  been in a rush and mixed up their results. Can
  you complete their table and fill in the missing
  gaps?

Making the bulb bright

• Which of the people do you agree with?

If I increase the voltage of the batteries the
bulb will be brighter.
If I add more bulbs the bulbs will be brighter.
If I add more components to my circuit the bulb
will become dimmer.

Your challenge!

• Your head teacher is a little worried that no-one
  would know if someone broke in through one of the
  classroom windows. Can you make an alarm that
  would work when a window is opened?
