Classroom Resources: Solutions
1 – 17 of 17 Classroom Resources
Solubility, Solubility Rules, Solute & Solvent, Intermolecular Forces, Chemical Bond, Ionic Bonding, Covalent Bonding, Polarity, Intermolecular Forces, Intramolecular Forces | High School, Middle School
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.
Solubility, Intermolecular Forces, Molarity | High School
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.
Solubility, Intermolecular Forces, Mixtures, Separating Mixtures | High School
In this lab, students will separate the component pigments of a water-soluble black marker using paper chromatography.
Mixtures, Solute & Solvent, Intermolecular Forces, Intermolecular Forces, Molecular Structure, Polymers, Electromagnetic Spectrum | Middle School, High School
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, Covalent Bonding, Polarity, Intermolecular Forces | High School
In this activity, students will learn about solubility, saturation, polarity, and intermolecular forces through chromatography techniques.
Solubility, Solute & Solvent, Molarity, Solubility Rules, Net Ionic Equation, Intermolecular Forces, Beer's Law | High School
The AACT high school classroom resource library and multimedia collection has everything you need to put together a unit plan for your classroom: lessons, activities, labs, projects, videos, simulations, and animations. We constructed a unit plan using AACT resources that is designed to teach Aqueous Solutions to your students.
Solubility, Solute & Solvent, Intermolecular Forces | Middle School, High School
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
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.
Intermolecular Forces, Intermolecular Forces, Physical Change | High School
In this demonstration, students observe and compare the properties of surface tension, beading, evaporation, and miscibility for water and acetone.
Mixtures, Solute & Solvent, Intermolecular Forces, Intermolecular Forces, Molecular Formula, Molecular Structure, Polymers, Electromagnetic Spectrum | Middle School, High School
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.
Scientific Method, Observations, Inferences, Intermolecular Forces, Mixtures | High School
In this lab, students will investigate the addition of detergent to a mixture of whole milk and food coloring. Students will attempt to explain the cause of their observations. Also, students will have the opportunity to manipulate the experiment and determine how other variables may impact the results.
Solubility, Solute & Solvent, Mixtures, Intermolecular Forces, Intermolecular Forces, Polarity, Molecular Geometry | Elementary School, Middle School, High School
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, Intermolecular Forces, Intermolecular Forces, Mixtures, Intramolecular Forces, Polarity, Observations, Physical Properties, Chemical Properties, Identifying an Unknown, Mixtures | High School
In this lesson, students determine whether unknown substances are polar, nonpolar, or ionic by testing their solubilities.
Intermolecular Forces, Mixtures, Intermolecular Forces, Colligative Properties, Freezing Point Depression, Solubility, Polarity, Phase Changes, Freezing Point, Density, Mixtures, Physical Properties | High School
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).
Polarity, Mixtures, Intermolecular Forces, Intermolecular Forces, Physical Properties, Observations, Mixtures | Middle School, Elementary School, High School
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.
Intermolecular Forces, Solute & Solvent, Scientific Method | High School
In this lab, students will investigate the idea that “like dissolves like” by discovering which liquids are best suited for dissolving various substances. This can serve as a great inquiry lab prior to teaching intermolecular forces.
Exothermic & Endothermic, Physical Change, Heat, Temperature, Observations, Intermolecular Forces, Solute & Solvent, Saturated/Unsaturated/Supersaturated | High School, Middle School
In this lesson, students will create a particulate model of matter that explains energy changes and transfer during a physical process, such as the crystallization of a solid from a supersaturated solution.
