Classroom Resources: Solutions

26 – 41 of 41 Classroom Resources

• 

  Solubility, Solute & Solvent, Reaction Rate, Physical Change | Elementary School

  Lab: M&M's Solution

  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.

• 

  Solubility, Solute & Solvent, Mixtures, Intermolecular Forces, Intermolecular Forces, Polarity, Molecular Geometry | Elementary School, Middle School, High School

  Animation: Solubility Animation

  This animation explores how ionic and molecular compounds dissolve (or don’t) in water. Students 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. **This video has no audio**

• 

  Solubility, Solute & Solvent, Precipitate, Saturated/Unsaturated/Supersaturated | High School, Elementary School, Middle School

  Lab: Winter Crystals

  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, Mixtures, Solubility, Percent Composition | Middle School

  Lab: The Perfect Kool-Aid Concentration

  In this lab, the students will investigate how the concentration of a solution affects its properties such as color and taste.

• 

  Colligative Properties, Specific Heat, Freezing Point Depression, Solute & Solvent, Concentration, Heat, Temperature, Calorimetry, Error Analysis | High School

  Lesson Plan: The Hot and Cold of it All

  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.

• 

  Solute & Solvent, Chemical Change, Solubility, Chemical Bond | Middle School

  Lab: A Sticky Situation

  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, Molarity, Tyndall Effect, Concentration, Stoichiometry, Dimensional Analysis, Mole Concept | High School

  Activity: Solubility & Solutions

  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.

• 

  Freezing Point, Solubility, Solute & Solvent, Phase Changes, Freezing Point Depression, Freezing Point, Physical Change, Physical Properties | Elementary School

  Lesson Plan: Salting Roads in Winter

  In this lesson, students investigate how the freezing point of water changes when salt is added.

• 

  Intermolecular Forces, Solute & Solvent, Scientific Method | High School

  Lab: Exploring Intermolecular Forces

  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.

• 

  Intermolecular Forces, Solubility, Intermolecular Forces, Intramolecular Forces, Polarity, Lewis Structures, Molecular Structure, Solute & Solvent, Mixtures, Melting Point, Freezing Point, Boiling Point, Physical Properties, Graphing, Mixtures | High School

  Lab: Physical Properties (High School)

  In this lesson, students investigate how intermolecular forces effect physical properties by investigating substances’ melting points as well as solubility.

• 

  Solubility, Solute & Solvent, Physical Change, Molecular Motion, Phase Changes, Reaction Rate | Elementary School

  Lesson Plan: Particles in Motion

  In this lesson, students learn that particles that make up matter are in constant motion.

• 

  Exothermic & Endothermic, Physical Change, Heat, Temperature, Observations, Intermolecular Forces, Solute & Solvent, Saturated/Unsaturated/Supersaturated | High School, Middle School

  Lesson Plan: Particle Modeling of Hand Warmers

  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.

• 

  Solute & Solvent, Physical Change, Solubility | Middle School, High School

  Lab: Chemistree

  In this lab, students will prepare a solution to observe a physical change.

• 

  Physical Change, Chemical Change, Solute & Solvent, Observations, Inferences, Physical Change, Identifying an Unknown | Elementary School

  Lesson Plan: Alien Invasion?

  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.

• 

  Mixtures, Physical Change, Physical Change, Solute & Solvent, Phase Changes, Distillation, Introduction, Separating Mixtures, Interdisciplinary, Mixtures | Elementary School

  Lesson Plan: Now I Can Drink the Water!
