Summary
The mole is a very large number used to measure the number of very small objects in chemistry. Using the mole to describe the number of a macroscopic object is not practical.

• HS-PS1-7: Use mathematical representations to support the claim that atoms, and therefore mass, are conserved during a chemical reaction.
Learning Goals/Student Objectives
Educational Goals: Reinforce the magnitude of a mole while simultaneously providing a visual for the size atoms must be when moles of atoms occupy very little space

Student Objectives:
Students will…
• Use the concept of the mole to determine the depth that one mole of rice would cover the surface of the earth if evenly spread over the planet's surface. This illustrates the magnitude of the size of a mole of rice.
