Classroom Resources: Solutions
26 – 36 of 36 Classroom Resources
Mixtures, Solubility, Intermolecular Forces, Polarity, Solute & Solvent, Intermolecular Forces, 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, Precipitate, Solute & Solvent, Saturated/Unsaturated/Supersaturated | Elementary School, Middle School, High School
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!
Observations, Separating Mixtures, Solubility, Concentration, Precipitate, Identifying an Unknown, Molarity, Net Ionic Equation, Balancing Equations, Percent Yield, Stoichiometry, Limiting Reactant, Mole Concept, Dimensional Analysis, Graphing | High School
In this lab, students use molarity concepts to review limiting reactant concepts mathematically, conceptually, and graphically. They can then carry out a follow up investigation to identify an unknown using concepts learned in the first investigation.
Solubility, Chemical Change, Precipitate, Net Ionic Equation, Balancing Equations, Chemical Change, Solubility Rules | High School
In this lab, students will mix ionic solutions to determine what combinations form precipitates.
Observations, Physical Properties, Mixtures, Solubility, Intermolecular Forces, Polarity, Identifying an Unknown, Intermolecular Forces, Chemical Properties, Intramolecular Forces, Mixtures | High School
In this lesson, students determine whether unknown substances are polar, nonpolar, or ionic by testing their solubilities.
Density, Physical Properties, Mixtures, Solubility, Freezing Point, Polarity, Phase Changes, Intermolecular Forces, Colligative Properties, Intermolecular Forces, Freezing Point Depression, Mixtures | 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).
Mixtures, Solubility, Reaction Rate, Saturated/Unsaturated/Supersaturated | High School
In this lab, students observe how particle size, solvent temperature, and agitation affect rate of solution.
Physical Properties, Mixtures, Solubility, Melting Point, Intermolecular Forces, Freezing Point, Polarity, Molecular Structure, Solute & Solvent, Intermolecular Forces, Boiling Point, Intramolecular Forces, Graphing, Mixtures, Lewis Structures | 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 | Middle School, High School
In this lab, students will prepare a solution to observe a physical change.
Solubility, Covalent Bonding, Precipitate, Ionic Bonding, Molecular Structure, Solute & Solvent, Saturated/Unsaturated/Supersaturated | Middle School, High School
In this lab, students create a snow globe by taking advantage of benzoic acid’s solubility properties in hot water.
Solubility, Concentration, Acid Base Reactions, Titrations, Indicators, pH | High School
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.
