• 

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

  Activity: T-Shirt Chromatography

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

• 

  Classification of Reactions, Balancing Equations, Solubility Rules, Activity Series | High School

  Activity: Simulation Activity: Predicting Products

  In this simulation, students will reference an activity series and a solubility chart to accurately predict the products of single replacement and double replacement chemical reactions. Associated particle diagrams will be displayed to help students better comprehend the reaction at the particulate level. Students will also be asked to balance the chemical equation. The simulation is designed as a five question quiz for students to use multiple times.

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

  Activity: Advanced Modeling of the Dissolving Phenomenon

  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.

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

  Activity: Basic Modeling of the Dissolving Phenomenon

  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.

  Physical Change, Chemical Change, Matter, Mixtures, Mixtures | Elementary School

  Activity: Chemistry in the Kitchen!

  In this activity, students will describe the steps required to complete a recipe of their choosing. They will identify any physical and chemical changes that occur throughout the process.

• 

  Molarity, Concentration, Molality | High School

  Activity: Particle Level Molarity

  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.

  Video: What is Paint? Video

  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

  Video: What are Pigments? Video

  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.

• 

  Physical Properties, Matter, Physical Change, Interdisciplinary, Separating Mixtures, Mixtures | Elementary School

  Activity: Creating Finger-Paint from Rocks

  In this activity, the students will explore the physical properties of different rocks. Students will have the opportunity to physically change the rocks, and make them part of a mixture in order to create finger paint.

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

  Animation: Solubility Animation

  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

  Animation: Net Ionic Equations Animation

  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**
