Do you have mole problems? If so, call Avogadro at 602-2140. The lesson starts with pupils working independently to solve for molar mass of ionic compounds. Then they learn to solve for percent composition and later perform an...

Building off young chemists' knowledge of the states of matter, kinetic molecular theory is the focus of the unit. Eight days of lessons including multiple demonstrations, one lab experiment, directed instruction, and worksheets,...

How many calculations can you think of that include moles? Chances are, plenty! Show young chemists the uses of the multifaceted mole with thought-provoking puzzles. Individuals identify and associate the outcomes of molar quantities...

By the end of this section, you will be able to state the ideal gas law in terms of molecules and in terms of moles; use the ideal gas law to calculate pressure change, temperature change, volume change, or the number of molecules or...

[Free Registration/Login Required] In the mole carnival, students count the number of atoms and particles in different objects found at the carnival. As students work to find the number of particles, they practice counting particles by...

The world's roundest object helps solve the longest running problem in measurement- how to define the kilogram. A kilogram isn't what it used to be. Literally. The name, weight, and definition of a kilogram has been changing constantly...

This is a glossary of terms and definitions used in Chapter 13: Temperature, Kinetic Theory, and the Gas Laws from the AP Physics online text.
