Classroom Resources: Solutions
26 – 38 of 38 Classroom Resources
Solute & Solvent, Concentration, Colligative Properties, Calorimetry, Heat, Specific Heat, Temperature, Freezing Point Depression, Error Analysis | High School
In this lesson students will analyze the effectiveness of different brands of antifreeze/coolants and their ability to protect an engine in cold climates. Students will conduct a lab investigation to examine the freezing point depression in samples that have been diluted with distilled water. Students will also determine the specific heat capacities of antifreeze/coolant products as compared to pure water and explain how it relates to thermal energy transfer in the internal combustion engine.
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.
Solute & Solvent, Concentration, 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.
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.
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, 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.
Solubility, Reaction Rate, Physical Change, Phase Changes, Solute & Solvent, Molecular Motion | Elementary School
In this lesson, students learn that particles that make up matter are in constant motion.
Observations, Physical Change, Solute & Solvent, Intermolecular Forces, Exothermic & Endothermic, Heat, Temperature, Saturated/Unsaturated/Supersaturated | Middle School, High 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.
Solubility, Physical Change, Solute & Solvent | Middle School, High School
In this lab, students will prepare a solution to observe a physical change.
Solubility, Solute & Solvent, Precipitate, Covalent Bonding, Ionic Bonding, Molecular Structure, 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.
Observations, Physical Change, Inferences, Physical Change, Solute & Solvent, Identifying an Unknown, Chemical Change | 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, Solute & Solvent, Interdisciplinary, Distillation, 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).
Mixtures, Solute & Solvent, Concentration, Molarity, Mole Concept, Dimensional Analysis, Measurements | High School
In this lab, students calculate concentrations of and perform dilutions of Kool-Aid and juice solutions.
