Percent Composition, Identifying an Unknown, Net Ionic Equation, Atomic Mass | High School
Lab: Analysis of Carbonate Compounds
In this lab, students identify three unknown substances by measuring the amount of product (CO2) produced by a reaction with hydrochloric acid.
-
Mixtures, Mixture, Chemical Change, Physical Change, Observations, Density, Acid Base Reactions, Chemical Change | Elementary School
Lab: Analyzing a Lava Lamp
In this lab, students create a mixture of oil, water and food coloring, and then add an Alka-Seltzer tablet, to create a homemade lava lamp. Student will record their observations during each step of the process and answer follow-up questions about the chemical and physical changes that took place.
-
Solubility, Acid Base Reactions, Titrations, Indicators, Intermolecular Forces, Concentration, pH | High School
Lab: Alka-Seltzer & Gas Solubility
In this lab, students will use a reaction to investigate temperature and the solubility of carbon dioxide and will use a neutralization reaction and an indicator to verify the amount of carbon dioxide produced at each temperature.
-
Physical Change, Chemical Change, Solute & Solvent, Observations, Inferences, Physical Change, Identifying an Unknown | Elementary School
Lesson Plan: Alien Invasion?
In this lesson, students will explore both physical and chemical changes as they try to help the Department of Homeland Security analyze and identify materials found in a mysterious capsule. Students will examine and observe an unknown object (a frozen water balloon) as it changes (melts). They then mix combinations of everyday substances to observe chemical changes.

Lesson Plan: Now I Can Drink the Water!
In this lesson, students review important concepts of the water cycle and then design, test, and evaluate a working model of a desalination plant (a distiller).
-
Molarity | High School
Lab: Molarity of a Solution
In this lab, students calculate concentrations of and perform dilutions of Kool-Aid and juice solutions.
