• 

  Density, Concentration, Solute & Solvent | High School

  Lab: Test Tube Challenge Mark as Favorite (47 Favorites)

  In this lab, students will be challenged to create a density column, consisting of three distinct layers of sugar-water solution. This is an inquiry lab, where the students must apply their understanding of density and concentration in order to devise a successful plan for creating the column correctly.

• 

  Molarity, Concentration, Mixtures, Solute & Solvent, Dimensional Analysis, Mole Concept, Measurements | High School

  Lab: Molarity of a Solution Mark as Favorite (44 Favorites)

  In this lab, students calculate concentrations of and perform dilutions of Kool-Aid and juice solutions.

• 

  Acid Rain, Acid Base Reactions, Chemical Change, Chemical Change, Indicators, Equivalence Point, pH, Concentration, Molarity | High School

  Lab: Seeing the Effects of Acid Rain Mark as Favorite (18 Favorites)

  In this lesson, students will prepare an environment and make acid rain to see how the acid rain effects the items in the environment.

• 

  Identifying an Unknown, Culminating Project, Classification of Reactions, Experimental Design, Scientific Method, Interdisciplinary, Review, Balancing Equations, Stoichiometry, Concentration, Molarity | High School

  Lab: The Culminating Unknown Mark as Favorite (35 Favorites)

  In this lab, students identify an unknown from a list of 12 possible compounds by designing a procedure and using evidence to prove their claim. They must draw from knowledge gained throughout the year to properly develop a procedure to identify the unknown.

• 

  Molarity, Concentration, Saturated/Unsaturated/Supersaturated, Mole Concept, Dimensional Analysis, Stoichiometry, Balancing Equations | High School

  Lab: Kool-Aid Mark as Favorite (81 Favorites)

  In this lab, students calculate grams of Kool-Aid powder required to make 3 different solutions of Kool-Aid (using the molar mass of sugar) with the following concentrations: 0.2 M, 0.5 M, and 1.0 M. Determine the concentration of properly prepared Kool-Aid through a taste test.

• 

  Molarity, Concentration, Mole Concept | High School

  Demonstration: What Is a 1 Molar Solution? Mark as Favorite (37 Favorites)

  In this demonstration, students will determine the molarity of several different solutions demonstrated by the teacher.

• 

  Solubility, Solute & Solvent, Concentration, Pressure, Temperature | High School

  Demonstration: Exploring Gas Solubility Mark as Favorite (14 Favorites)

  In this demonstration, students will explore how changes in pressure and temperature affect the solubility of a gas in an aqueous solution. In addition, students will have the opportunity in a post-demonstration reflection activity to practice using data (in this case their demonstration observations) to make evidence based claims.

• 

  Concentration, Solute & Solvent, Chemical Change | Elementary School, Middle School

  Demonstration: Soft Eggs Mark as Favorite (2 Favorites)

  In this demonstration, students will first observe a reaction between vinegar (acetic acid) and an egg shell (calcium carbonate) to produce a naked egg. Using these eggs, student will analyze how certain substances can move through a membrane and also determine if the membrane is affected.
