Activity: Simulation Activity: The Effect of Solutes on Boiling and Freezing Point Mark as Favorite (43 Favorites)
In this activity, students will use a colligative properties simulation to investigate the effects of different solutes, and different amounts of those solutes, on the boiling point and freezing point of a solution. Students will see particle-level animations of boiling and freezing with different types and amounts of solutes, as well as graphical representations of the results of each trial.

Solubility Rules, Solubility, Ionic Bonding, Predicting Products | High School
Activity: Solubility Rules Dice Game Mark as Favorite (46 Favorites)
In this activity, students will use ion dice to form a number of different ionic compounds. Based on the resulting ionic compound, they will use a solubility chart to determine if it is soluble or insoluble. This game will allow students to become more familiar with ionic compounds and solubility rules.

Activity: Ingenious: How Science Is Fixing Recycling's Grossest Problem Video Questions Mark as Favorite (4 Favorites)
In this activity, students will answer questions while watching the video, How Science is Fixing Recycling’s Grossest Problem, from the Ingenious series produced by the American Chemical Society. Each episode investigates a different topic related to how leading-edge chemistry is taking on the world’s most urgent issues to advance everyone’s quality of life and secure our shared future. This episode investigates the stinky problems associated with polypropylene recycling. Current polypropylene recycling techniques are more down-cycling than re-cycling, but a new technique, called dissolution recycling, is changing all that.

Solubility, Intermolecular Forces, Molarity | High School
Activity: Solutions Escape Room Mark as Favorite (81 Favorites)
In this activity, students will review concepts covered in a solutions unit. They will complete problems in order to determine codes that will allow them to advance through stages of a Google Form, which is set up as an escape room. This activity is designed to be used at the end of a unit, or as an alternate to an exam, particularly in a virtual environment.

Ionic Bonding, Naming Compounds, Molecular Formula, Ions, Ionic Radius, Solubility, Melting Point, Physical Properties | High School
Activity: My Name is Bond, Ionic Bond Mark as Favorite (74 Favorites)
In this lesson, students will demonstrate their knowledge of ionic bond strength using a “brackets” activity. Pairs of students start the activity playing a game of “Ionic Compound War” to build eight compounds. Then then transfer the compounds to a “bracket” and use their knowledge of ionic bonding, along with a solubility chart, to predict the strongest and weakest bond between four pairs of ionic substances.

Solute & Solvent, Intermolecular Forces, Solubility | Middle School, High School
Activity: Basic Modeling of the Dissolving Phenomenon Mark as Favorite (54 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.

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.

Solute & Solvent, Molarity, Tyndall Effect, Concentration, Stoichiometry, Dimensional Analysis, Mole Concept | High School
Activity: Solubility & Solutions Mark as Favorite (22 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.
