Oompa Loompa’s plea for help

As part of Willow’s Charlie and the Chocolate Factory themed science unit, the children tried to help the Oompa Loompa’s boost the conductivity of Wonka Vision.

The children had to test different metals to see which was the best electrical conductor. Mike TeaVee would then be able to see a chocolate bar be transported from the invention room to his television.

In groups, the children built a stand for the lightbulb and circuit and tested different metals using a light meter. Results did differ. Some found platinum the best electrical conductor, others found copper to be effective.

Unfortunately, Mike TeaVee didn’t wait for the Oompa Loompa’s to conclude testing and jumped into the Wonka Vision machine. He ended up the size of a pencil and on the way to the stretching room in his mum’s pocket.

Great experiment Willow Class!
