51 – 57 of 57 Classroom Resources
Concentration, Molarity, Balancing Equations, Stoichiometry, Mole Concept, Dimensional Analysis, Saturated/Unsaturated/Supersaturated | High School
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.
Mixtures, Concentration, Solute & Solvent, Molarity, Mole Concept, Dimensional Analysis, Measurements | High School
In this lab, students calculate concentrations of and perform dilutions of Kool-Aid and juice solutions.
Concentration, Solute & Solvent, Molarity, Stoichiometry, Mole Concept, Dimensional Analysis, Tyndall Effect | High School
In this inquiry activity, students investigate types of solutions, identifying the solute and solvent, and classifying each solution. They them solve stoichiometry problems involving solutions of different concentrations.
Chemical Change, Reaction Rate, Catalysts, Balancing Equations, Percent Yield, Stoichiometry, Chemical Change, Dimensional Analysis, Measurements, Scientific Method, Error Analysis, Experimental Design, Error Analysis | High School
In this lesson students will be introduced to catalysts while expanding their knowledge of chemical reactions and stoichiometry. They will first learn about catalytic converters and then be challenged to create the best “catalytic converter” of hydrogen peroxide to oxygen gas in an inquiry-based activity.
Percent Composition, Percent Composition, Mole Concept, Dimensional Analysis | High School
In this lab, students will be introduced to the concept of percent composition. Students will determine the amount of sweetener in various brands of gum by determining the mass difference of the gum before and after it is chewed.
Molecular Formula, Law of Definite Proportions, Stoichiometry, Classification of Reactions, Mole Concept, Dimensional Analysis | High School
In this lab, students will recognize that oxygen has mass and that heating can involve and increase in mass as an element reacts to become an oxide
Density, Review, Accuracy, Dimensional Analysis, Measurements, Accuracy, Experimental Design, Error Analysis | High School, Middle School
In this lab, students will find the density of a bowling ball to determine whether it will sink or float in water.
