This is a very simple set of instructions for building a model of an s-atomic orbital using craft store supplies. It is a good visual aide to use when describing three-dimensional boundary surface diagrams. This model will compliment nicely our p-orbital and d-orbital models described in other links.
Materials
A styrofoam ball approximately 4 inches in diameter.
A 3 inch length of 1/8 in. dowel rod.
A 4 inch length of 1x4 board.
Sandpaper and glue
Drill and 1/8 in. bit
Drill a vertical hole in the center of the 1x4 board. Sand the board smooth. Sharpen one end of the
dowel and glue it, sharp end up, in the hole.
Add a few drops of glue to the peg and push the styrofoam ball on it until it touches the base.
Be sure to get the ball centered. Add a label and your s-orbital model is ready for display.
