Relevant Standards
Standard 3.3 The student will investigate and
understand that objects are made of materials
that can be described by their physical
properties. Key concepts include a) objects are
made of one or more materials b) materials are
composed of parts that are too small to be seen
without magnification c) physical properties
remain the same as the material is reduced in
size.
4
Relevant Standards
Standard 5.4 The student will investigate and
understand that matter is anything that has mass,
takes up space, and occurs as a solid, liquid, or
gas. Key concepts include a) atoms, elements,
molecules, and compounds b) mixtures including
solutions and c) the effect of heat on the
states of matter.

Atomic Dimensions
Approximately how many atoms of copper are
present in a 3-g pre-1982 penny?
atomic weight of copper
63.546 g (for every mole of copper atoms)
One mole of anything is equivalent to 6.02 X 1023
? Cu atoms is approximately 3 X 1022

Atomic Dimensions
How high would a stack of pennies be if it
contained 3 X 1022 pre-1982 pennies?
The height of one penny is approximately 1 mm.
The stack would be 3 X 1022 mm high.
What is this height in miles?
The average distance to the moon is approximately
240,000 mi.
There are approximately 7 X 109 people in this
world.
