Classroom Resources: Solutions
26 – 44 of 44 Classroom Resources
Solubility, Solute & Solvent | Middle School, High School
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
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.
Solubility, Reaction Rate, Solute & Solvent, Physical Change | Elementary School
In this lab, students will investigate dissolving using M&M’s and will determine whether dissolving happens faster without assistance, or with the assistance of the tongue and teeth.
Mixtures, Solubility, Solute & Solvent, Intermolecular Forces, Polarity, 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, Solute & Solvent, Precipitate, 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, Precipitate, Chemical Change, 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.
Mixtures, Solubility, Solute & Solvent, Concentration, Percent Composition | Middle School
In this lab, the students will investigate how the concentration of a solution affects its properties such as color and taste.
Solubility, Solute & Solvent, Chemical Change, Chemical Bond | Middle School
In this lab, students will try to separate plastic spoons that have been attached together with different adhesive materials using a variety of solvents.
Separating Mixtures, Mixtures, Solubility, Phase Changes, Physical Change | Middle School
In this lab, students will perform a step by step process of mixing and separating substances based on their states and solubility in order to solve a problem.
Observations, Physical Properties, Mixtures, Solubility, Identifying an Unknown, Intermolecular Forces, Polarity, Intermolecular Forces, Chemical Properties, Mixtures, Intramolecular Forces | 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, Phase Changes, Polarity, 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).
Physical Properties, Solubility, Freezing Point, Phase Changes, Physical Change, Solute & Solvent, Freezing Point Depression, Freezing Point | Elementary School
In this lesson, students investigate how the freezing point of water changes when salt is added.
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, Freezing Point, Solute & Solvent, Intermolecular Forces, Polarity, Molecular Structure, Intermolecular Forces, Boiling Point, Lewis Structures, Mixtures, Intramolecular Forces, Graphing | High School
In this lesson, students investigate how intermolecular forces effect physical properties by investigating substances’ melting points as well as solubility.
