Science lab

Today we had a incursion, we went to the senior school to the science lab and did a experiment the experiment was…see if different materials were metal or not. We had a little kit were we clipped the materials and see if the little light bulb would light up, if it did this is called conducting electricity. On the paper we had to write the results there were questions and here were a few.  Can you polish it, is it magnetic, does it conduct electricity, is it heavy for its size, does the material make a rings sound when you hit it with a hard object, does the material conduct heat and is the material strong. There were also different materials wood, plastic, tin, aluminium, nickel,  rubber, copper, and cardboard. 

Here are the results.
