Tell thechildren that when they wash their hands at a sink theywill need to turn off the water faucet without havingdirect contact with the handle. T o do this they will use aclean, dry paper towel to cover the handle beforetouching it (this prevents the transfer of germs from thehandle back to the hands). 4 Before starting the next activity, get cooking oil(enough for each child to have a dime-sizedamount), and a shakable container of cinnamon spice.
A: Copper is classified as a metal on the periodic table and is therefore not classified according to family in the manner that plants and animals are. Copper is red-colored. It is malleable, ductile, and a good conductor of heat and electricity.
Copper is a metal that consists of a lattice of atoms, and you can imagine it like so: In 1 cm^3 piece of copper, there are about 10^23 of those little blue balls we call atoms. In each of those atoms, there are outer shells where electrons flow freely and, when bonded together with other atoms, join the free electrons of the other atoms. What we get is a so-called sea of electrons that flow from atom to atom, and it is precisely this that makes the copper conductive.
