1 – 5 of 5 Classroom Resources

• New

  

  Equilibrium, Le Châtelier's Principle, Predicting Products, Percent Composition, Acids & Bases, Acid Base Reactions | High School

  Lesson Plan: Crest Toothpaste Mark as Favorite (3 Favorites)

  In this lesson, students will learn about the development of Crest fluoridated toothpaste by reading an article and engaging in related activities. The activities help promote literacy in the science classroom. Parts of this lesson could be used as plans for a substitute teacher.

• 

  Titrations, Indicators, Acid Base Reactions, Stoichiometry, Percent Composition | High School

  Lab: The Egg-straordinary Issue Mark as Favorite (87 Favorites)

  In this lab students will determine the percent composition of calcium carbonate contained in an eggshell by using a back titration in order to address a farmer’s concerns about his hen’s fragile eggs. Two versions of the student lab are included, a scripted version, and an inquiry version.

• 

  Percent Composition, Identifying an Unknown, Net Ionic Equation, Stoichiometry, Error Analysis, Molar Mass | High School

  Lab: Analysis of Carbonate Compounds Mark as Favorite (66 Favorites)

  In this lab, students calculate the molar masses of three unknown carbonate compounds by measuring the amount of product (CO2) produced by a reaction with hydrochloric acid.

• 

  Percent Composition, Mole Concept, Identifying an Unknown, Emission Spectrum, Empirical Formula, Percent Composition | High School

  Lesson Plan: Chemical Analysis of Martian Rocks Mark as Favorite (122 Favorites)

  In this lesson, students are challenged to analyze the spectral graphs obtained by the Curiosity Mars Rover. Based on their examination students will determine the component elements of each sample, as well as the relative abundance of each element. With this information the student will complete calculations to find the empirical formula and identify the composition of the unknown rock. Finally students will complete research to see if these rocks are actually like those on Earth.

• 

  Stoichiometry, Limiting Reactant, Percent Composition, Lewis Structures, Percent Composition | High School

  Lab: Untouchable Key Escape Room Mark as Favorite (120 Favorites)

  In this lab, students are presented with a key wrapped in aluminum foil a quantity of solid copper (II) chloride, a balance, distilled water and a selection of standard laboratory glassware and equipment. Without using their hands to touch the key, students must react the key with a copper (II) chloride solution in order to free the key and use it to escape from the chemistry classroom!
