Science – Changing materials
In 5B we have been looking at materials and their properties. Today we looked at insulators and conductors and what this means. We investigated different materials to test whether they were an insulator or a conductor. It all started with building a circuit using a cell, wires and a bulb. Next, we added different materials to our circuit using crocodile clips; if the bulb lit up then it was a conductor, if the bulb did not light up it was an insulator. After that, we ranked them from the brightest bulb to the dimmest bulb which told us which was the best conductor. In our table groups, we presented our findings to the rest of the class according to which conductor we thought would be best to use for some new floodlights at a football stadium.
