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

    Access is an AACT member benefit. 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.

  • Mixtures, Chemical Change, Physical Change, Observations, Density, Acid Base Reactions, Chemical Change, Mixtures | Elementary School

    Access is an AACT member benefit. 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.

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

    Access is an AACT member benefit. 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.

  • Solubility, Acid Base Reactions, Titrations, Indicators, Concentration, pH | High School

    Access is an AACT member benefit. 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

    Access is an AACT member benefit. 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.

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

    Access is an AACT member benefit. 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.

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

    Access is an AACT member benefit. 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.

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

    Access is an AACT member benefit. 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.

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

    Access is an AACT member benefit. 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, Concentration, Mixtures, Solute & Solvent, Dimensional Analysis, Mole Concept, Measurements | High School

    Access is an AACT member benefit. Lab: Molarity of a Solution

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

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

    Access is an AACT member benefit. 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.

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

    Access is an AACT member benefit. 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.

  • Balancing Equations, Conservation of Mass, Conservation of Matter, Conservation of Matter, Chemical Change, Chemical Change, Conservation of Mass, Polyatomic Ions, Precipitate | 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.
