  Solubility, Solute & Solvent, Intermolecular Forces | Middle School, High School

  Activity: Advanced Modeling of the Dissolving Phenomenon Mark as Favorite (29 Favorites)

  In this activity students build a model of sodium chloride based on their own knowledge of ionic compounds. Then they construct a model of the interactions between water and their salt model to develop an understanding of what caused the salt to dissolve. After refining their models based upon class discussions and critiques, students then construct a model of the interaction between salt and a different solvent, alcohol. Using their models, students make predictions as to which solvent (water or alcohol) would be better at dissolving the salt. Finally students design an experiment to test their prediction. As an extension, students are asked to use their solubility models to explain why calcium carbonate will not dissolve in water, even though it is also an ionic compound.

  Physical Change, Chemical Change, Matter, Mixtures, Mixtures | Elementary School

  Activity: Chemistry in the Kitchen! Mark as Favorite (8 Favorites)

  In this activity, students will describe the steps required to complete a recipe of their choosing. They will identify any physical and chemical changes that occur throughout the process.

• 

  Molarity, Concentration, Molality | High School

  Activity: Particle Level Molarity Mark as Favorite (93 Favorites)

  In this activity, students are introduced to molarity at the particle level. Students will activate their prior knowledge by demonstrating their understanding of concentration by preparing several Kool-Aid drinks, and then applying that information at the particle level to various models.

• 

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

  Activity: Solubility & Solutions Mark as Favorite (22 Favorites)

  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.

• 

  Observations, Mixtures, Density, Physical Properties, Mixtures | Elementary School

  Activity: Color-Works in a Jar Mark as Favorite (2 Favorites)

  Students will be using three ingredients to create a liquid color-works mixture in a jar. This is a fun chemistry project to do with young elementary students around the 4th of July or New Year’s Eve to get the children excited about fireworks.

• 

  Ionic Bonding, Naming Compounds, Precipitate, Ions, Molecular Formula | Middle School

  Activity: Bond with a Classmate Mark as Favorite (38 Favorites)

  In this activity, students are assigned an ion and form bonds with their classmates, recording the formula and name of the compound they created.

• 

  Balancing Equations, Conservation of Mass, Conservation of Matter, Conservation of Matter, Chemical Change, Chemical Change, Conservation of Mass, Polyatomic Ions, Precipitate | Middle School, High School

  Activity: Simulation Activity: Balancing Chemical Equations Mark as Favorite (100 Favorites)

  In this activity, students will learn how to count atoms and how to balance chemical equations using a simulation and games from PhET Interactive Simulations.
