Light the paper from the alcohol flame and toss it up into the air. Bring in samples of a few elements, particularly metals and some nonmetals such as sulfur, iodine, chlorine, and bromine.
If you wish, illustrate the relative chemical inactivity of helium by inhaling a bit and speaking in a squeaky voice. Obtain and display a lead pig used for transport of radiochemicals. Spend a little time differentiating metals and nonmetals as to luster, ductility, malleability, and conductivity. What characteristic of metals that makes them conductive? As a special project, have a student draw a graph of atomic weight versus discovery date of elements. Balloons can be inflated and tied together to represent p orbitals.
An s orbital can be illustrated by putting a penny into a balloon, inflating the balloon and tying it, and then moving the balloon in a circular motion so that the penny spins around the inside of the balloon. Obtain laser pointers in blue and red colors.
