  Freezing Point Depression, Heat, Phase Changes, Molecular Motion | Middle School, High School

  Lab: Sweet, Salty and Cold as Ice Mark as Favorite (33 Favorites)

  In this lab, students conduct a micro-scale investigation to explore how various solutes affect the freezing point of water. Because of the small volume of liquid used, results are visible within minutes. Students observe what happens to the liquids as they are cooled and use their observations to infer what is going on at the particle level. They will use the results to explain the familiar phenomena of why we salt our roads and sidewalks in the winter and why freshwater lakes and ponds freeze over more easily than saltwater oceans in the winter.

  Heat, Temperature, Specific Heat, Observations, Molecular Motion | High School, Middle School

  Activity: What Makes Something Feel Warm Mark as Favorite (58 Favorites)

  In this lesson students actively engage in thinking about energy issues in chemistry and the nature of energy (thermal) transfer. The idea that temperature is a measure of heat content will be challenged, and students will be given the opportunity to collect data that will allow them to clearly see that different materials transfer energy at different rates.

• 

  Molecular Motion, Physical Properties | Middle School, High School

  Activity: Categorizing States of Matter Mark as Favorite (101 Favorites)

  In this activity students will analyze both written statements and images that describe the properties of a solid, liquid or gas. Students will determine which state of matter the description best describes and categorize it accordingly.

• 

  Phase Changes, Molecular Motion | Middle School, High School

  Activity: Simulation Activity: States of Matter and Phase Changes Mark as Favorite (68 Favorites)

  In this simulation, students will participate in a 10 question quiz. Some questions will challenge students to analyze data to identify the correct state of matter for a specific sample, and then connect the chosen state with an animated particle diagram. In addition, students will examine the behavior of particles in an animated sample as they undergo a phase change, and must correctly identify the change that occurs.

• 

  Molecular Motion, Molecular Motion | High School

  Activity: The Molecule Dance Mark as Favorite (14 Favorites)

  In this activity, students will explain bond and molecular movements by mimicking molecular motion with their own movements.

• 

  Temperature, Molecular Motion, Observations, Inferences | High School, Middle School

  Demonstration: What is Temperature? Mark as Favorite (62 Favorites)

  In this demonstration, students will observe food dye mixing with water at different temperatures.

• 

  Pressure, Gas Laws, Kinetic Molecular Theory, Temperature, Volume, Molecular Motion, Intermolecular Forces | High School, Middle School

  Lab: Gas Pressure Mark as Favorite (41 Favorites)

  In this lab, students will understand what causes pressure in a container and the variables that affect pressure (volume, temperature, number of moles) by mimicking molecular motion of gases.
