• 

  Physical Change, Mixtures, Observations | High School, Middle School

  Activity: Magic Bubble Mark as Favorite (7 Favorites)

  In this lesson, students will create and interpret particle diagrams that represent elements and compounds at the molecular level. They will also describe the process of dissolving and create particle diagrams that represent mixtures at the molecular level.

• 

  Chemical Change, Observations, Acids & Bases, Chemical Change, Mixtures | Elementary School, Middle School, High School

  Demonstration: Inflating a Balloon with Chemistry Mark as Favorite (29 Favorites)

  In this demonstration, the teacher will perform a reaction between acetic acid (vinegar) and sodium bicarbonate (baking soda) in order to inflate a balloon and to introduce the concept of a chemical reaction to students. Students will observe the reaction, and identify indicators of chemical change as well as discuss the different types of matter that are involved.

• 

  Density, Observations, Inferences, Mixtures, Mixtures | Middle School, High School

  Demonstration: Density Tubes Mark as Favorite (3 Favorites)

  In this demonstration, students will have the opportunity to observe and analyze the density of a solution. Students will interpret their observations as they compare the density of the solution with plastic components.

• 

  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 (165 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.

• 

  Culminating Project, Review, Physical Properties, Chemical Properties, Periodic Table, History, Interdisciplinary, Electron Configuration, Subatomic Particles, Isotopes, Atomic Mass | High School, Middle School

  Project: 21st Century Elements Mark as Favorite (40 Favorites)

  In this project, students will learn the importance of the elements in our lives. The students will research one chosen element and create a website, a digital comic strip, or a video to explain the important properties of the element as well as why the element is so important to our lives.

• 

  Molecular Motion, Density, Physical Properties, Density, Gas Laws, Ideal Gas, Temperature, Pressure, Volume | Middle School, High School

  Simulation: Density Mark as Favorite (14 Favorites)

  The simulation for the September 2015 issue allows students to investigate the effect of changing variables on both the volume and the density of a solid, a liquid, and a gas sample. Students will analyze the different states of matter at the particle level as well as quantitatively.

  Density, Molecular Motion | Middle School, High School

  Activity: Simulation Activity: Density Simulation Mark as Favorite (29 Favorites)

  In this simulation, students will investigate the effect of changing variables on both the volume and the density of a solid, a liquid and a gas sample. Students will analyze the different states of matter at the particle level as well as quantitatively. This lesson accompanies the simulation from the September 2015 issue of Chemistry Solutions.

• 

  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 (99 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.
