  • 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.

  • Solubility, pH, Molecular Structure, Buffers | High School

    Lab: Aspirin Tablets: Are they all the Same?

    In this lab, students will design an experiment to test the time and completeness of dissolution of various types of aspirin in different pH environments.

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

    Lab: What's the Solution?

    In this lab students will choose one factor that can affect the rate at which a solute will dissolve into solution –amount of stirring, temperature, or particle size, and will design a procedure that can be used to determine how it will affect rate of solution. Students will identify one of the factors above as the independent variable and will determine how it affects the solubility rate as supported by time required to dissolve the solute.

  • Solubility, Solute & Solvent | High School

    Demonstration: Root Beer Chemistry

    In this demonstration, students will understand the factors affecting solubility of both a solid and a gas in a liquid through the process of making root beer.

  • 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**

  • Solubility, Precipitate, Solute & Solvent | Middle School, Elementary School, High School

    Lab: Winter Crystals

    In this lab, students will create a supersaturated solution by dissolving borax in boiling water. They will create a snowflake using pipe cleaner to suspend in the solution, which will serve as a nucleation site for crystallization as the solution cools and remains undistributed overnight. This lab gives students an opportunity to experience the exciting crystallization process and become more familiar with an engaging chemistry spectacle!

  • Solubility, Intermolecular Forces | High School

    Lab: Solubility & Compound Type

    In this lesson, students determine whether unknown substances are polar, nonpolar, or ionic by testing their solubilities.

  • Solubility, Solubility | High School

    Lab: Rate of Solution

    In this lab, students observe how particle size, solvent temperature, and agitation affect rate of solution.

  • Solubility, Intermolecular Forces, Intermolecular Forces | High School

    Lab: Physical Properties (High School)

    In this lesson, students investigate how intermolecular forces effect physical properties by investigating substances’ melting points as well as solubility.

  • Solubility, Physical Change, Solute & Solvent | High School, Middle School

    Lab: Chemistree

    In this lab, students will prepare a solution to observe a physical change.

  • Solubility | Middle School, High School

    Lab: Benzoic Acid Blizzard in a Bottle

    In this lab, students create a snow globe by taking advantage of benzoic acid’s solubility properties in hot water.

  • Solubility, Acid Base Reactions, Intermolecular Forces, Titrations, Indicators | High School

    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.
