Classroom Resources: Solutions
26 – 37 of 37 Classroom Resources
Solubility, Precipitate, Solute & Solvent, Saturated/Unsaturated/Supersaturated | High School, Elementary School, Middle 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!
Concentration, Solute & Solvent, Molarity, Stoichiometry, Mole Concept, Dimensional Analysis, Tyndall Effect | High School
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.
Solute & Solvent, Intermolecular Forces, 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.
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.
Mixtures, Solubility, Percent Composition, Concentration, Solute & Solvent | Middle School
In this lab, the students will investigate how the concentration of a solution affects its properties such as color and taste.
Solubility, Physical Change, Solute & Solvent | Middle School, High School
In this lab, students will prepare a solution to observe a physical change.
Solubility, Chemical Change, Solute & Solvent, 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.
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.
Observations, Chemical Change, Physical Change, Inferences, Physical Change, Identifying an Unknown, Solute & Solvent | Elementary School
In this lesson, students will explore both physical and chemical changes as they try to help the Department of Homeland Security analyze and identify materials found in a mysterious capsule. Students will examine and observe an unknown object (a frozen water balloon) as it changes (melts). They then mix combinations of everyday substances to observe chemical changes.
Separating Mixtures, Mixtures, Physical Change, Physical Change, Phase Changes, Introduction, Interdisciplinary, Distillation, Solute & Solvent, Mixtures | Elementary School
In this lesson, students review important concepts of the water cycle and then design, test, and evaluate a working model of a desalination plant (a distiller).
Solubility, Physical Change, Phase Changes, Reaction Rate, Solute & Solvent, Molecular Motion | Elementary School
In this lesson, students learn that particles that make up matter are in constant motion.
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.
