  Mixtures, Physical Properties, Molecular Structure, Mixtures | Elementary School, Middle School, High School

  Demonstration: Analyzing Mixtures Mark as Favorite (36 Favorites)

  In this demonstration, the teacher will create a sequence of mixtures in a single test tube. Water, oil, food coloring and soap will be used in this demonstration to introduce the concepts of heterogeneous and homogeneous solutions as well as the idea of miscibility. Students will also have the opportunity to analyze the properties, such as surface tension of each component used.

• 

  Percent Composition, Identifying an Unknown, Net Ionic Equation, Stoichiometry, Error Analysis, Molar Mass | High School

  Lab: Analysis of Carbonate Compounds Mark as Favorite (56 Favorites)

  In this lab, students calculate the molar masses of three unknown carbonate compounds by measuring the amount of product (CO2) produced by a reaction with hydrochloric acid.

• 

  Molecular Formula, History, Functional Groups, Covalent Bonding, Molecular Structure | High School

  Activity: Napoleon's Buttons Writing Assignment Mark as Favorite (25 Favorites)

  In this activity, students read Penny Le Couteur and Jay Burreson’s book Napoleon’s Buttons: How 17 Molecules Changed History. They discuss the book in class and complete a written assignment based on the chemistry and history highlighted in the book.

• 

  Naming Compounds, Covalent Bonding | High School

  Lesson Plan: Naming Covalent Compounds Mark as Favorite (86 Favorites)

  In this lesson, students engage their literacy skills to interpret tables and answer a series of guiding questions to discover the rules of naming and formula writing for simple covalent compounds.

  Naming Compounds | High School

  Activity: Naming Compounds Mark as Favorite (48 Favorites)

  From this reference, students will gain a better understanding of how to name compounds.

• 

  Molecular Formula, Atomic Mass, Molar Mass | High School

  Activity: Molecule Building Tournament Mark as Favorite (12 Favorites)

  In this activity, students determine molecular formulas given formula masses and a limited number of atoms.

• 

  Gas Laws, Molar Mass, Density, Temperature, Pressure, Volume, Ideal Gas, Physical Change, Observations, Density, Identifying an Unknown, Error Analysis | High School

  Lab: Molar Mass of Dry Ice Mark as Favorite (12 Favorites)

  In this lab, students will use gas laws to calculate the molar mass of dry ice and then use the information to identify the compound that makes up this substance.

• 

  Periodic Table, Physical Properties, Identifying an Unknown, Ionization Energy, Atomic Radius, Electronegativity | High School

  Activity: Mendeleev's Periodic Table Mark as Favorite (50 Favorites)

  In this activity, students will use their knowledge of Periodic Trends to analyze and identify unknown elements and organize them correctly in the Periodic Table.

• 

  Molecular Formula, Ionic Bonding, Covalent Bonding, Molecular Geometry, Naming Compounds, Lewis Structures, Periodic Table, Valence Electrons, Lewis Dot Diagrams, Ions, Subatomic Particles | High School, Middle School

  Simulation: Ionic & Covalent Bonding Mark as Favorite (160 Favorites)

  In the September 2016 simulation, students investigate both ionic and covalent bonding. Students will have the opportunity to interact with many possible combinations of atoms and will be tasked with determining the type of bond and the number of atom needed to form each. Students will become familiar with the molecular formula, as well as the naming system for each type of bond and geometric shape, when applicable.

• 

  Intermolecular Forces, Polarity, Molecular Motion, Intermolecular Forces, Molecular Motion, Physical Change | High School

  Simulation: Comparing Attractive Forces Mark as Favorite (38 Favorites)

  In the November 2014 issue, students explore the different attractive foreces between pairs of molecules by dragging the "star" image. In the accompanying activity, students investigate different types of intermolecular forces (London dispersion and dipole-dipole). In the analysis that follows the investigation, they relate IMFs (including hydrogen bonding) to physical properties (boiling point and solubility).
