Key Concepts for Learning:

Students will understand the property of solubility by comparing the solubility of different solutes.

Lesson Design:

Students have measured the solubility of salt: 15g per 50mL water. Students will measure the solubility of citric acid and compare it to the solubility of salt to determine high and low solubility.

Student Quotes:

“Why is it (citric acid) taking so long to dissolve?” Dakota

“This takes FORE’VER!” Julia

“I need a machine to shake it.” Faitala

“Shake it real good!” Kienan

“This is never going to saturate.” Sean & Rachel

“I think we have to keep doing it ‘til it take up the full volume of the bottle.” Anthony
