Choosing materials for making loops?(Activity)



Finding materials which conduct more or less well


What the activity is for

Here the aim is to introduce the idea that materials are better or worse for making electrical loops, and that we might usefully remember which are which by labelling these materials. those which are good for making loops we might call conductors and those which are not so good we might call insulators.


What the activity is for

  • a set of simple test circuits containing a bulb and a battery, as well as the terminals in which to place the test item
  • a collection of suitable test materials

  • What happens during this activity

    Introduce the activity as a way of deciding which materials might be good for building electrical loops. If the bulb comes on then an material might well be put in the more suitable collection, otherwise the material should be placed in the less suitable collection.

    Some discussion about the kinds of materials you have in each block is likely to reveal that many of those label conductors are metals: take care though–perhaps not all.

    Teacher Tip: Try to avoid the suggestion that the distinction between in insulators and conductors is absolute.
