Students will be asked to make observations about two different salt water samples to determine if a sample that contains undissolved salt is still considered a solution.

  • 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.

  • Observations, Physical Properties, Mixtures, Solute & Solvent, Mixture | Middle School

    Lesson Plan: How Fast Does it Flow?

    In this lesson students explore the viscosity of different mixtures. They measure viscosity of different mixtures and then have the opportunity to design a mixture to attain a particular viscosity. Students will relate their lab experience to the application of viscosity in the real-world as they consider the differences in viscosity between different types of paints.

  • Separating Mixtures, Physical Properties, Mixtures, Solute & Solvent | Middle School, Elementary School

    Lab: What Does Ironman Eat for Breakfast?

  • Separating Mixtures, Mixtures, Molecular Structure, Solute & Solvent | High School

    Lesson Plan: What Type of Mixture is Paint?

    In this lesson students will use simple laboratory tests to characterize differences between solutions, colloids, and suspensions. They will then apply those tests to paints to classify them as specific types of mixtures.
