  • Solubility, Solute & Solvent, Precipitate, Covalent Bonding, Ionic Bonding, Molecular Structure, Saturated/Unsaturated/Supersaturated | Middle School, High School

    Lab: Benzoic Acid Blizzard in a Bottle

    In this lab, students create a snow globe by taking advantage of benzoic acid’s solubility properties in hot water.

  • Physical Properties, Mixtures, Molecular Structure, Mixtures | Elementary School, Middle School, High School

    Demonstration: Analyzing Mixtures

    In this demonstration, the teacher will create a sequence of mixtures in a single test tube. Water, oil, food coloring and soap will be used in this demonstration to introduce the concepts of heterogeneous and homogeneous solutions as well as the idea of miscibility. Students will also have the opportunity to analyze the properties, such as surface tension of each component used.

  • Identifying an Unknown, Net Ionic Equation, Stoichiometry, Percent Composition, Molar Mass, Error Analysis | High School

    Lab: Analysis of Carbonate Compounds

    In this lab, students calculate the molar masses of three unknown carbonate compounds by measuring the amount of product (CO2) produced by a reaction with hydrochloric acid.

  • Observations, Density, Mixtures, Physical Change, Chemical Change, Chemical Change, Acid Base Reactions, Mixtures | 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, Concentration, Intermolecular Forces, Titrations, Indicators, Acid Base Reactions, 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.

  • Observations, Physical Change, Inferences, Physical Change, Solute & Solvent, Identifying an Unknown, Chemical Change | 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.

  • Concentration, Chemical Change, Chemical Change, Molarity, Balancing Equations, Stoichiometry, Limiting Reactant, Chemical Change, Titrations, Indicators, Measurements, Acid Base Reactions, Graphing, Error Analysis, Error Analysis, Equivalence Point | High School

    Lab: Acid-Base Mole Ratio

    In this lab, students study several concepts, including acid-base reactions, limiting reactants, and stoichiometry, by observing the contained reaction of acetic acid (diluted vinegar) with sodium hydrogen carbonate (baking soda) in an unconventional, cost effective titration.

  • Concentration, Molarity, Stoichiometry, Limiting Reactant, Indicators, Mole Concept, Dimensional Analysis, Measurements, Acid Base Reactions, pH | High School

    Lab: Acid/Base Stoichiometry

    In this lab, students experience a limiting reactant and can physically see the difference in amounts of product generated. They also see which reactant is in excess.

  • Concentration, Molarity, Titrations, Indicators, Strong vs Weak, Measurements, Acid Base Reactions, Equivalence Point, pH | High School

    Lab: Acid Base Reactions

    In this lab, students will witness a reaction between an acid and base. One will be strong, and the other may be weak or strong--it's up to them to determine.

  • Separating Mixtures, Mixtures, Physical Change, Physical Change, Phase Changes, Introduction, Solute & Solvent, Interdisciplinary, Distillation, Mixtures | Elementary School

    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).

  • Mixtures, Solute & Solvent, Concentration, Molarity, Mole Concept, Dimensional Analysis, Measurements | High School

    Lab: Molarity of a Solution

    In this lab, students calculate concentrations of and perform dilutions of Kool-Aid and juice solutions.

  • Precipitate, Naming Compounds, Ionic Bonding, Molecular Formula, Ions | Middle School

    Activity: Bond with a Classmate

    In this activity, students are assigned an ion and form bonds with their classmates, recording the formula and name of the compound they created.

  • Observations, Density, Mixtures, Inferences, Mixtures | Middle School, High School

    Demonstration: Density Tubes

    In this demonstration, students will have the opportunity to observe and analyze the density of a solution. Students will interpret their observations as they compare the density of the solution with plastic components.

  • Conservation of Matter, Precipitate, Conservation of Mass, Polyatomic Ions, Chemical Change, Balancing Equations, Conservation of Mass, Chemical Change, Conservation of Matter | Middle School, High School

    Activity: Simulation Activity: Balancing Chemical Equations

    In this activity, students will learn how to count atoms and how to balance chemical equations using a simulation and games from PhET Interactive Simulations.
