  • Solubility, Solute & Solvent, Intermolecular Forces, Covalent Bonding, Polarity, Intermolecular Forces | High School

    Access is an AACT member benefit. Activity: T-Shirt Chromatography Mark as Favorite (45 Favorites)

    In this activity, students will learn about solubility, saturation, polarity, and intermolecular forces through chromatography techniques.

  • Solute & Solvent, Intermolecular Forces, Solubility | Middle School, High School

    Access is an AACT member benefit. Activity: Basic Modeling of the Dissolving Phenomenon Mark as Favorite (49 Favorites)

    In this activity, students explore the process of salt dissolving in water using cut-outs of ions and water molecules to model interactions between them. They then use their model to make a prediction about the relative solubility of salt in isopropyl alcohol compared to the solubility in water and design an experiment to test their prediction.

  • Solubility, Solute & Solvent, Intermolecular Forces | Middle School, High School

    Access is an AACT member benefit. Activity: Advanced Modeling of the Dissolving Phenomenon Mark as Favorite (29 Favorites)

    In this activity students build a model of sodium chloride based on their own knowledge of ionic compounds. Then they construct a model of the interactions between water and their salt model to develop an understanding of what caused the salt to dissolve. After refining their models based upon class discussions and critiques, students then construct a model of the interaction between salt and a different solvent, alcohol. Using their models, students make predictions as to which solvent (water or alcohol) would be better at dissolving the salt. Finally students design an experiment to test their prediction. As an extension, students are asked to use their solubility models to explain why calcium carbonate will not dissolve in water, even though it is also an ionic compound.

  • Molarity, Concentration, Molality | High School

    Access is an AACT member benefit. Activity: Particle Level Molarity Mark as Favorite (83 Favorites)

    In this activity, students are introduced to molarity at the particle level. Students will activate their prior knowledge by demonstrating their understanding of concentration by preparing several Kool-Aid drinks, and then applying that information at the particle level to various models.

  • Mixtures, Solute & Solvent, Intermolecular Forces, Intermolecular Forces, Molecular Formula, Molecular Structure, Polymers, Electromagnetic Spectrum | Middle School, High School

    Access is an AACT member benefit. Video: What is Paint? Video Mark as Favorite (17 Favorites)

    This video investigates the composition of paint, while analyzing the fundamental chemistry principles of its main components. Students will learn about the differences between three common paint types, water colors, oil-based and acrylic paint as well as the chemistry of each.

  • Electromagnetic Spectrum, Molecular Structure, Mixtures | Middle School, High School

    Access is an AACT member benefit. Video: What are Pigments? Video Mark as Favorite (14 Favorites)

    This video discusses the chemistry of pigment molecules and how they are used to give paints their specific color. Students will learn about the importance of a pigment’s molecular structure, how they are physically suspended to create a paint color, as well as how they interact with light.

  • Solubility, Solute & Solvent, Mixtures, Intermolecular Forces, Intermolecular Forces, Polarity, Molecular Geometry | Elementary School, Middle School, High School

    Access is an AACT member benefit. Animation: Solubility Animation Mark as Favorite (76 Favorites)

    This animation explores how ionic and molecular compounds dissolve (or don’t) in water. Students will see that if an ionic compound such as salt dissolves, the ions dissociate, whereas the molecules in a molecular compound such as sugar remain intact but are separated from one another by water molecules. They will also see that some ionic compounds such as chalk do not dissolve, and the cations and anions remain stuck together. **This video has no audio**

  • Balancing Equations, Precipitate, Solubility Rules | High School

    Access is an AACT member benefit. Animation: Net Ionic Equations Animation Mark as Favorite (60 Favorites)

    This animation explores what happens in a precipitate reaction on the particulate level. Students will see why writing a net ionic equation accurately represents what happens in these scenarios. An example of diluting a soluble solid, mixing two aqueous reactants that yield aqueous products, and mixing two aqueous reactants that yield a precipitate are part of this animation. **This video has no audio**

  • Solute & Solvent, Molarity, Tyndall Effect, Concentration, Stoichiometry, Dimensional Analysis, Mole Concept | High School

    Access is an AACT member benefit. Activity: Solubility & Solutions Mark as Favorite (21 Favorites)

    In this inquiry activity, students investigate types of solutions, identifying the solute and solvent, and classifying each solution. They them solve stoichiometry problems involving solutions of different concentrations.

  • 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 Mark as Favorite (85 Favorites)

    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.
