• 

  Solubility, Intermolecular Forces, Molarity | High School

  Activity: Solutions Escape Room Mark as Favorite (81 Favorites)

  In this activity, students will review concepts covered in a solutions unit. They will complete problems in order to determine codes that will allow them to advance through stages of a Google Form, which is set up as an escape room. This activity is designed to be used at the end of a unit, or as an alternate to an exam, particularly in a virtual environment.

  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.

• 

  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.

• 

  Ionic Bonding, Naming Compounds, Molecular Formula, Ions, Ionic Radius, Solubility, Melting Point, Physical Properties | High School

  Activity: My Name is Bond, Ionic Bond Mark as Favorite (74 Favorites)

  In this lesson, students will demonstrate their knowledge of ionic bond strength using a “brackets” activity. Pairs of students start the activity playing a game of “Ionic Compound War” to build eight compounds. Then then transfer the compounds to a “bracket” and use their knowledge of ionic bonding, along with a solubility chart, to predict the strongest and weakest bond between four pairs of ionic substances.

• 

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

  Activity: Basic Modeling of the Dissolving Phenomenon Mark as Favorite (54 Favorites)

  In this activity, students explore the process of salt dissolving in water using cut-outs of ions and water molecules to model interactions between them. They then use their model to make a prediction about the relative solubility of salt in isopropyl alcohol compared to the solubility in water and design an experiment to test their prediction.

  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.

• 

  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.
