  Lesson Plan: Fuel Line Antifreeze Mark as Favorite (14 Favorites)

  In this lesson students will explore the role of a gasoline additive, fuel line antifreeze (generally methanol or 2‑propanol), in reducing the potential of water to block fuel lines in freezing weather. Students will prepare test tube models of water-contaminated fuel tanks and explore the effect of adding different types of fuel line antifreeze. This lesson can be used to bolster concepts about miscibility, density, intermolecular forces, phase changes (freezing), and colligative properties (freezing point depression).

  Lesson Plan: Salting Roads in Winter Mark as Favorite (3 Favorites)

  In this lesson, students investigate how the freezing point of water changes when salt is added. Many students know that water freezes at 0°C, and many believe that all substances freeze at 0°C. The investigations in this lesson help students understand why salt is spread on roads in cold and snowy conditions.

  Lab: Physical Properties (High School) Mark as Favorite (29 Favorites)

  In this lesson, students investigate how intermolecular forces effect physical properties by investigating substances’ melting points as well as solubility.

• 

  Solubility, Solute & Solvent, Molecular Motion, Phase Changes, Reaction Rate | Elementary School

  Lesson Plan: Particles in Motion Mark as Favorite (1 Favorite)

  In this lesson, students learn that particles that make up matter are in constant motion.

  Solute & Solvent, Physical Change, Solubility | Middle School, High School

  Lab: Chemistree Mark as Favorite (18 Favorites)

  In this lab, students will prepare a solution to observe a physical change.

• 

  Solubility, Acid Base Reactions, Titrations, Indicators, Concentration, pH | High School

  Lab: Alka-Seltzer & Gas Solubility Mark as Favorite (18 Favorites)

  In this lab, students will use a reaction to investigate temperature and the solubility of carbon dioxide and will use a neutralization reaction and an indicator to verify the amount of carbon dioxide produced at each temperature.

• 

  Solubility, Saturated/Unsaturated/Supersaturated, Mixtures, Reaction Rate | High School

  Lab: Rate of Solution Mark as Favorite (22 Favorites)

  In this lab, students observe how particle size, solvent temperature, and agitation affect rate of solution.
