Journal Entry:
 Five gummy bears have been placed overnight in five different aqueous sugar solutions. Each solution contains a different amount of dissolved sugar.

1. Which solution do you think has the greatest amount of sugar in it? Explain your reasoning.

2. What do you think caused the bears to change in size?

Learning Intentions

• We will learn how to calculate molarity of a solution.
• We will learn how to make a saturated solution and determine its molarity
•  We will learn how solutes and solvents move into and out of substances in solution.

Closing Task:

You can determine the molarity of a solution

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)
