Learning Intentions

• We will learn how to determine large amounts of small objects.
•  We will learn how to calculate percent error.

Closing Task:

 You can calculate the number of objects using mass and sample size and calculate percent error.

Content Standards being covered:

Student understands what the letters and numbers stand for in a compound formula, can use those letter and numbers to determine how many of each type of element there are in a formula.

Student can create mathematical representations of chemical reactions and use them to make calculations about products and reactants.

Students can use mathematical representations to support the claim that atoms, and therefore mass, are conserved during a chemical reaction. (HS-PS1-7 and CCC Energy and Matter)
