Solubility, Solubility Rules, Solute & Solvent, Intermolecular Forces, Chemical Bond, Ionic Bonding, Covalent Bonding, Polarity, Intermolecular Forces, Intramolecular Forces | High School, Middle School
Activity: Animation Activity: Solubility
In this activity, students will use an animation to visualize how ionic and molecular compounds dissolve (or don’t) in water. They 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.

Colligative Properties, Boiling Point Elevation, Freezing Point Depression, Concentration, Solute & Solvent, Boiling Point, Freezing Point, Phase Changes, Molecular Motion, Graphing, Physical Properties, Heat, Temperature | High School, Middle School
Activity: Simulation Activity: The Effect of Solutes on Boiling and Freezing Point
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.

Physical Properties, Covalent Bonding, Electronegativity, Polarity, Molecular Geometry, Intermolecular Forces, Solubility | Middle School, High School
Activity: The Chemistry of Water Video Questions
In this lesson, students will watch a video and answer questions about how the molecular geometry and polarity of water give rise to many of its unusual physical properties, including its relatively high boiling point and its ability to dissolve some substances but not others.
-
Concentration, Physical Properties, Chemical Properties, pH | Middle School
Activity: Would You Drink it?
In this activity, students are provided with data regarding the water quality at multiple locations throughout a city. Students will determine which location should be prioritized for cleaning of contaminates. Students will utilize Claim Evidence and Reasoning (CER) to develop a claim that is supported by the data provided.

Electromagnetic Spectrum, Molecular Structure, Mixtures | Middle School, High School
Activity: What are Pigments? Video Questions
In this activity, students will watch a video and answer related questions about the chemistry of pigment molecules and how they are used to give paints their specific color. During the video, 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.

Mixtures, Solute & Solvent, Intermolecular Forces, Intermolecular Forces, Molecular Structure, Polymers, Electromagnetic Spectrum | Middle School, High School
Activity: What is Paint? Video Questions
In this activity, students will watch a video and answer related questions about the composition of paint. During the video, 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.

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.

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