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

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

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

    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.

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

    Animation: Solubility Animation

    In an animation, students will have an opportunity to visualize on the particulate level how solubility works. Examples of ionic compounds and a polar covalent compound show how when water is attracted to charged parts, they dissolve, and when they're not attracted to charged parts they stay solid. **This video has no audio**

  • Chemical Change, Intermolecular Forces, Polarity, Polymers, Molecular Structure, Intermolecular Forces, Scientific Method, Monomer | Middle School

    Lesson Plan: Watch the Baby! Superabsorbent Polymer

    In this lesson, students will learn about how polymers, specifically superabsorbent polymers, work. Through lab activities, students will investigate polymer properties.

  • Mixtures, Intermolecular Forces, Intermolecular Forces | Middle School, High School

    Lesson Plan: Fuel Line Antifreeze

    In this lesson students will explore the role of a gasoline additive, fuel line antifreeze (generally methanol or 2‑propanol), in reducing the potential of water to block fuel lines in freezing weather. Students will prepare test tube models of water-contaminated fuel tanks and explore the effect of adding different types of fuel line antifreeze. This lesson can be used to bolster concepts about miscibility, density, intermolecular forces, phase changes (freezing), and colligative properties (freezing point depression).

  • Physical Change, Intermolecular Forces, Polarity, Physical Change, Intermolecular Forces, Matter | Middle School

    Lesson Plan: Sandy Beaches—A Foray into ‘Magic’ Sand

    In this lesson, students will investigate the properties of magic sand and learn about the concept of hydrophobic and hydrophilic molecules. It also introduced students to the field of nanotechnology.

  • Observations, Physical Properties, Mixtures, Intermolecular Forces, Polarity, Intermolecular Forces, Mixture | High School, Elementary School, Middle School

    Lab: Salad Dressing Science: Emulsions

    In this lab, students mix polar and nonpolar substances and then add various emulsifiers to encourage the mixing of the two substances. They use ingredients in salad dressing to relate science to real life scenarios.
